65	<desc>
66	Welcome to the <b>VirtualBox Main API documentation</b>. This documentation
67	describes the so-called <i>VirtualBox Main API</i> which comprises all public
68	COM interfaces and components provided by the VirtualBox server and by the
69	VirtualBox client library.
70
71	VirtualBox employs a client-server design, meaning that whenever any part of
72	VirtualBox is running -- be it the Qt GUI, the VBoxManage command-line
73	interface or any virtual machine --, a dedicated server process named
74	VBoxSVC runs in the background. This allows multiple processes working with
75	VirtualBox to cooperate without conflicts. These processes communicate to each
76	other using inter-process communication facilities provided by the COM
77	implementation of the host computer.
78
79	On Windows platforms, the VirtualBox Main API uses Microsoft COM, a native COM
80	implementation. On all other platforms, Mozilla XPCOM, an open-source COM
81	implementation, is used.
82
83	All the parts that a typical VirtualBox user interacts with (the Qt GUI,
84	the VBoxManage command-line interface and the VBoxVRDP server) are technically
85	front-ends to the Main API and only use the interfaces that are documented
86	in this Main API documentation. This ensures that, with any given release
87	version of VirtualBox, all capabilities of the product that could be useful
88	to an external client program are always exposed by way of this API.
89
90	The VirtualBox Main API (also called the <i>VirtualBox COM library</i>)
91	contains two public component classes:
92	<tt>%VirtualBox.VirtualBox</tt> and <tt>%VirtualBox.Session</tt>, which
93	implement IVirtualBox and ISession interfaces respectively. These two classes
94	are of supreme importance and will be needed in order for any front-end
95	program to do anything useful. It is recommended to read the documentation of
96	the mentioned interfaces first.
97
98	The <tt>%VirtualBox.VirtualBox</tt> class is a singleton. This means that
99	there can be only one object of this class on the local machine at any given
100	time. This object is a parent of many other objects in the VirtualBox COM
101	library and lives in the VBoxSVC process. In fact, when you create an instance
102	of the <tt>VirtualBox.VirtualBox</tt>, the COM subsystem checks if the VBoxSVC
103	process is already running, starts it if not, and returns you a reference to
104	the <tt>VirtualBox</tt> object created in this process. When the last reference
105	to this object is released, the VBoxSVC process ends (with a 5 second delay to
106	protect from too frequent restarts).
107
108	The <tt>%VirtualBox.Session</tt> class is a regular component. You can create
109	as many <tt>Session</tt> objects as you need but all of them will live in a
110	process which issues the object instantiation call. <tt>Session</tt> objects
111	represent virtual machine sessions which are used to configure virtual
112	machines and control their execution.

238	<desc>
239	This section describes all VirtualBox-specific COM result codes that may
240	be returned by methods of VirtualBox COM interfaces in addition to
241	standard COM result codes.
242
243	Note that along with the result code, every VirtualBox method returns
244	extended error information through the IVirtualBoxErrorInfo interface on
245	failure. This interface is a preferred way to present the error to the end
246	user because it contains a human readable description of the error. Raw
247	result codes, both standard and described in this section, are intended to
248	be used by programs to analyze the reason of a failure and select an
249	appropriate course of action without involving the end user (for example,
250	retry the operation later or make a different call).
251
252	The standard COM result codes that may originate from our methods include:
253
254	<table>
255	<tr><td>E_INVALIDARG</td>
256	<td>
257	Returned when the value of the method's argument is not within the range
258	of valid values. This should not be confused with situations when the
259	value is within the range but simply doesn't suit the current object
260	state and there is a possibility that it will be accepted later (in such
261	cases VirtualBox-specific codes are returned, for example,
262	<link to="VBOX_E_OBJECT_NOT_FOUND"/>).
263	</td>
264	</tr>
265	<tr><td>E_POINTER</td>
266	<td>
267	Returned if a memory pointer for the output argument is invalid (for
268	example, @c null). Note that when pointers representing input
269	arguments (such as strings) are invalid, E_INVALIDARG is returned.
270	</td>
271	</tr>
272	<tr><td>E_ACCESSDENIED</td>
273	<td>
274	Returned when the called object is not ready. Since the lifetime of a
275	public COM object cannot be fully controlled by the implementation,
276	VirtualBox maintains the readiness state for all objects it creates and
277	returns this code in response to any method call on the object that was
278	deactivated by VirtualBox and is not functioning any more.
279	</td>
280	</tr>
281	<tr><td>E_OUTOFMEMORY</td>
282	<td>
283	Returned when a memory allocation operation fails.
284	</td>

478	Virtual machine execution state.
479
480	This enumeration represents possible values of the <link
481	to="IMachine::state"/> attribute.
482
483	Below is the basic virtual machine state diagram. It shows how the state
484	changes during virtual machine execution. The text in square braces shows
485	a method of the IConsole interface that performs the given state
486	transition.
487
488	<pre>
489	+---------[powerDown()] <- Stuck <--[failure]-+
490	V \|
491	+-> PoweredOff --+-->[powerUp()]--> Starting --+ \| +-----[resume()]-----+
492	\| \| \| \| V \|
493	\| Aborted -----+ +--> Running --[pause()]--> Paused
494	\| \| ^ \| ^ \|
495	\| Saved -----------[powerUp()]--> Restoring -+ \| \| \| \|
496	\| ^ \| \| \| \|
497	\| \| +-----------------------------------------+-\|-------------------+ +
498	\| \| \| \| \|
499	\| \| +-- Saving <--------[takeSnapshot()]<-------+---------------------+
500	\| \| \| \|
501	\| +-------- Saving <--------[saveState()]<----------+---------------------+
502	\| \| \|
503	+-------------- Stopping -------[powerDown()]<----------+---------------------+
504	</pre>
505
506	Note that states to the right from PoweredOff, Aborted and Saved in the
507	above diagram are called <i>online VM states</i>. These states
508	represent the virtual machine which is being executed in a dedicated
509	process (usually with a GUI window attached to it where you can see the
510	activity of the virtual machine and interact with it). There are two
511	special pseudo-states, FirstOnline and LastOnline, that can be used in
512	relational expressions to detect if the given machine state is online or
513	not:
514
515	<pre>
516	if (machine.GetState() >= MachineState_FirstOnline &&
517	machine.GetState() <= MachineState_LastOnline)
518	{
519	...the machine is being executed...
520	}
521	</pre>
522
523	When the virtual machine is in one of the online VM states (that is, being
524	executed), only a few machine settings can be modified. Methods working
525	with such settings contain an explicit note about that. An attempt to
526	change any oter setting or perform a modifying operation during this time
527	will result in the <link to="VBOX_E_INVALID_VM_STATE"/> error.
528
529	All online states except Running, Paused and Stuck are transitional: they
530	represent temporary conditions of the virtual machine that will last as
531	long as the operation that initiated such a condition.
532
533	The Stuck state is a special case. It means that execution of the machine
534	has reached the "Guru Meditation" condition. This condition indicates an
535	internal VMM (virtual machine manager) failure which may happen as a
536	result of either an unhandled low-level virtual hardware exception or one
537	of the recompiler exceptions (such as the <i>too-many-traps</i>
538	condition).
539
540	Note also that any online VM state may transit to the Aborted state. This
541	happens if the process that is executing the virtual machine terminates
542	unexpectedly (for example, crashes). Other than that, the Aborted state is
543	equivalent to PoweredOff.
544
545	There are also a few additional state diagrams that do not deal with
546	virtual machine execution and therefore are shown separately. The states
547	shown on these diagrams are called <i>offline VM states</i> (this includes
548	PoweredOff, Aborted and Saved too).
549
550	The first diagram shows what happens when a lengthy setup operation is
551	being executed (such as <link to="IMachine::attachDevice"/>).
552
553	<pre>
554	+----------------------------------(same state as before the call)------+
555	\| \|
556	+-> PoweredOff --+ \|
557	\| \| \|
558	\|-> Aborted -----+-->[lengthy VM configuration call] --> SettingUp -----+
559	\| \|
560	+-> Saved -------+
561	</pre>
562
563	The next two diagrams demonstrate the process of taking a snapshot of a
564	powered off virtual machine and performing one of the "discard..."
565	operations, respectively.
566
567	<pre>
568	+----------------------------------(same state as before the call)------+
569	\| \|
570	+-> PoweredOff --+ \|
571	\| +-->[takeSnapshot()] -------------------> Saving ------+
572	+-> Aborted -----+
573
574	+-> PoweredOff --+
575	\| \|
576	\| Aborted -----+-->[discardSnapshot() ]-------------> Discarding --+
577	\| \| [discardCurrentState()] \|
578	+-> Saved -------+ [discardCurrentSnapshotAndState()] \|
579	\| \|
580	+---(Saved if restored from an online snapshot, PoweredOff otherwise)---+
581	</pre>
582
583	Note that the Saving state is present in both the offline state group and
584	online state group. Currently, the only way to determine what group is
585	assumed in a particular case is to remember the previous machine state: if
586	it was Running or Paused, then Saving is an online state, otherwise it is
587	an offline state. This inconsistency may be removed in one of the future
588	versions of VirtualBox by adding a new state.
589
590	<note internal="yes">
591	For whoever decides to touch this enum: In order to keep the
592	comparisons involving FirstOnline and LastOnline pseudo-states valid,
593	the numeric values of these states must be correspondingly updated if
594	needed: for any online VM state, the condition
595	<tt>FirstOnline <= state <= LastOnline</tt> must be
596	@c true. The same relates to transient states for which
597	the condition <tt>FirstOnline <= state <= LastOnline</tt> must be
598	@c true.

1007	uuid="4b86d186-407e-4f9e-8be8-e50061be8725"

1011	<desc>
1012	The IVirtualBoxErrorInfo interface represents extended error information.
1013
1014	Extended error information can be set by VirtualBox components after
1015	unsuccessful or partially successful method invocation. This information
1016	can be retrieved by the calling party as an IVirtualBoxErrorInfo object
1017	and then shown to the client in addition to the plain 32-bit result code.
1018
1019	In MS COM, this interface extends the IErrorInfo interface,
1020	in XPCOM, it extends the nsIException interface. In both cases,
1021	it provides a set of common attributes to retrieve error
1022	information.
1023
1024	Sometimes invocation of some component's method may involve methods of
1025	other components that may also fail (independently of this method's
1026	failure), or a series of non-fatal errors may precede a fatal error that
1027	causes method failure. In cases like that, it may be desirable to preserve
1028	information about all errors happened during method invocation and deliver
1029	it to the caller. The <link to="#next"/> attribute is intended
1030	specifically for this purpose and allows to represent a chain of errors
1031	through a single IVirtualBoxErrorInfo object set after method invocation.

1033	Note that errors are stored to a chain in the reverse order, i.e. the
1034	initial error object you query right after method invocation is the last
1035	error set by the callee, the object it points to in the @a next attribute
1036	is the previous error and so on, up to the first error (which is the last

1609	<method name="createMachine">
1610	<desc>
1611	Creates a new virtual machine.
1612
1613	The new machine is created unregistered, with the initial configuration
1614	set according to the specified guest OS type. A typical sequence of
1615	actions to create a new virtual machine is as follows:
1616
1617	<ol>
1618	<li>
1619	Call this method to have a new machine created. The returned machine
1620	object will be "mutable" allowing to change any machine property.
1621	</li>
1622
1623	<li>
1624	Configure the machine using the appropriate attributes and methods.
1625	</li>
1626
1627	<li>
1628	Call <link to="IMachine::saveSettings" /> to write the settings
1629	to the machine's XML settings file. The configuration of the newly
1630	created machine will not be saved to disk until this method is
1631	called.
1632	</li>
1633
1634	<li>
1635	Call <link to="#registerMachine" /> to add the machine to the list
1636	of machines known to VirtualBox.
1637	</li>
1638	</ol>
1639
1640	You should specify valid name for the newly created machine when calling
1641	this method. See the <link to="IMachine::name"/> attribute description
1642	for more details about the machine name.
1643
1644	The specified guest OS type identifier must match an ID of one of known
1645	guest OS types listed in the <link to="IVirtualBox::guestOSTypes"/>
1646	array.
1647
1648	Every machine has a <i>settings file</i> that is used to store
1649	the machine configuration. This file is stored in a directory called the
1650	<i>machine settings subfolder</i>. Both the settings subfolder and file
1651	will have a name that corresponds to the name of the virtual machine.
1652	You can specify where to create the machine setting subfolder using the
1653	@a baseFolder argument. The base folder can be absolute (full path) or
1654	relative to the <link to="IVirtualBox::homeFolder">VirtualBox home
1655	directory</link>.
1656
1657	If @a baseFolder is a @c null or empty string (which is recommended), the
1658	<link to="ISystemProperties::defaultMachineFolder">default machine
1659	settings folder</link> will be used as a base folder for the created
1660	machine. Otherwise the given base folder will be used. In either case,
1661	the full path to the resulting settings file has the following
1662	structure:
1663	<pre>
1664	<base_folder>/<machine_name>/<machine_name>.xml
1665	</pre>
1666
1667	Note that if the resulting settings file already exists, this method
1668	will fail with <link to="VBOX_E_FILE_ERROR"/>.
1669
1670	Optionally, you may specify an UUID of to assign to the created machine.
1671	However, this is not recommended and you should normally pass an empty
1672	(@c null) UUID to this method so that a new UUID will be automatically
1673	generated for every created machine. You can use UUID
1674	00000000-0000-0000-0000-000000000000 as @c null value.
1675
1676	<note>
1677	There is no way to change the name of the settings file or
1678	subfolder of the created machine directly.

2452	<method name="openSession">
2453	<desc>
2454	Opens a new direct session with the given virtual machine.
2455
2456	A direct session acts as a local lock on the given VM.
2457	There can be only one direct session open at a time for every
2458	virtual machine, protecting the VM from being manipulated by
2459	conflicting actions from different processes. Only after a
2460	direct session has been opened, one can change all VM settings
2461	and execute the VM in the process space of the session object.
2462
2463	Sessions therefore can be compared to mutex semaphores that
2464	lock a given VM for modification and execution.
2465	See <link to="ISession">ISession</link> for details.
2466
2467	<note>Unless you are writing a new VM frontend, you will not
2468	want to execute a VM in the current process. To spawn a new
2469	process that executes a VM, use
2470	<link to="IVirtualBox::openRemoteSession" />
2471	instead.</note>
2472
2473	Upon successful return, the session object can be used to
2474	get access to the machine and to the VM console.
2475
2476	In VirtualBox terminology, the machine becomes "mutable" after
2477	a session has been opened. Note that the "mutable" machine
2478	object, on which you may invoke IMachine methods to change its
2479	settings, will be a different object from the immutable IMachine
2480	objects returned by various IVirtualBox methods. To obtain a
2481	mutable IMachine object (upon which you can invoke settings methods),
2482	use the <link to="ISession::machine" /> attribute.
2483
2484	One must always call <link to="ISession::close" /> to release the
2485	lock on the machine, or the machine's state will eventually be
2486	set to "Aborted".
2487
2488	In other words, to change settings on a machine, the following
2489	sequence is typically performed:
2490
2491	<ol>
2492	<li>Call this method (openSession) to have a machine locked for
2493	the current session.</li>
2494

2496
2497	<li>Change the settings of the machine.</li>
2498
2499	<li>Call <link to="IMachine::saveSettings" />.</li>

2537	<method name="openRemoteSession">
2538	<desc>
2539	Spawns a new process that executes a virtual machine (called a
2540	"remote session").
2541
2542	Opening a remote session causes the VirtualBox server to start a new
2543	process that opens a direct session with the given VM. As a result, the
2544	VM is locked by that direct session in the new process, preventing
2545	conflicting changes from other processes. Since sessions act as locks
2546	that prevent conflicting changes, one cannot open a remote session
2547	for a VM that already has another open session (direct or remote), or
2548	is currently in the process of opening one (see <link
2549	to="IMachine::sessionState"/>).
2550
2551	While the remote session still provides some level of control over the
2552	VM execution to the caller (using the <link to="IConsole" /> interface),
2553	not all VM settings are available for modification within the remote
2554	session context.
2555
2556	This operation can take some time (a new VM is started in a new process,
2557	for which memory and other resources need to be set up). Because of this,
2558	an <link to="IProgress" /> is returned to allow the caller to wait for this
2559	asynchronous operation to be completed. Until then, the remote session
2560	object remains in the closed state, and accessing the machine or its
2561	console through it is invalid. It is recommended to use
2562	<link to="IProgress::waitForCompletion" /> or similar calls to wait for
2563	completion.
2564
2565	As with all <link to="ISession" /> objects, it is recommended to call
2566	<link to="ISession::close" /> on the local session object once openRemoteSession()
2567	has been called. However, the session's state (see <link to="ISession::state" />)
2568	will not return to "Closed" until the remote session has also closed (i.e.
2569	until the VM is no longer running). In that case, however, the state of
2570	the session will automatically change back to "Closed".
2571
2572	Currently supported session types (values of the @a type
2573	argument) are:
2574	<ul>
2575	<li><tt>"gui"</tt>: VirtualBox Qt GUI session</li>
2576	<li><tt>"vrdp"</tt>: VirtualBox VRDP Server session</li>
2577	<li><tt>"sdl"</tt>: VirtualBox SDL GUI session</li>
2578	</ul>
2579
2580	The @a environment argument is a string containing definitions of
2581	environment variables in the following format:
2582	@code
2583	NAME[=VALUE]\n
2584	NAME[=VALUE]\n
2585	...
2586	@endcode
2587	where <tt>\\n</tt> is the new line character. These environment
2588	variables will be appended to the environment of the VirtualBox server
2589	process. If an environment variable exists both in the server process
2590	and in this list, the value from this list takes precedence over the
2591	server's variable. If the value of the environment variable is
2592	omitted, this variable will be removed from the resulting environment.
2593	If the environment string is @c null or empty, the server environment
2594	is inherited by the started process as is.

2727	<desc>
2728	Blocks the caller until any of the properties represented by the
2729	@a what argument changes the value or until the given timeout interval
2730	expires.
2731
2732	The @a what argument is a comma separated list of property masks that
2733	describe properties the caller is interested in. The property mask is
2734	a string in the following format:
2735
2736	<pre>
2737	[[group.]subgroup.]name
2738	</pre>
2739
2740	where @c name is the property name and @c group, @c subgroup are zero
2741	or more property group specifiers. Each element (group or name) in
2742	the property mask may be either a Latin string or an asterisk symbol
2743	(@c "*") which is used to match any string for the given element. A
2744	property mask that doesn't contain asterisk symbols represents a
2745	single fully qualified property name.
2746
2747	Groups in the fully qualified property name go from more generic (the
2748	left-most part) to more specific (the right-most part). The first
2749	element is usually a name of the object the property belongs to. The
2750	second element may be either a property name, or a child object name,
2751	or an index if the preceding element names an object which is one of
2752	many objects of the same type. This way, property names form a
2753	hierarchy of properties. Here are some examples of property names:
2754
2755	<table>
2756	<tr>
2757	<td><tt>VirtualBox.version</tt></td>
2758	<td><link to="IVirtualBox::version"/> property</td>
2759	</tr>
2760	<tr>
2761	<td><tt>Machine.<UUID>.name</tt></td>
2762	<td><link to="IMachine::name"/> property of the machine with the
2763	given UUID</td>
2764	</tr>
2765	</table>
2766
2767	Most property names directly correspond to the properties of objects
2768	(components) provided by the VirtualBox library and may be used to
2769	track changes to these properties. However, there may be
2770	pseudo-property names that don't correspond to any existing object's
2771	property directly, as well as there may be object properties that
2772	don't have a corresponding property name that is understood by this
2773	method, and therefore changes to such properties cannot be
2774	tracked. See individual object's property descriptions to get a
2775	fully qualified property name that can be used with this method (if
2776	any).
2777
2778	There is a special property mask @c "*" (i.e. a string consisting of a
2779	single asterisk symbol) that can be used to match all properties.
2780	Below are more examples of property masks:
2781
2782	<table>
2783	<tr>
2784	<td><tt>VirtualBox.*</tt></td>
2785	<td>Track all properties of the VirtualBox object</td>
2786	</tr>
2787	<tr>
2788	<td><tt>Machine.*.name</tt></td>
2789	<td>Track changes to the <link to="IMachine::name"/> property of
2790	all registered virtual machines</td>

3033	<desc>
3034	Represents a platform-independent appliance in OVF format. An instance of this is returned
3035	by <link to="IVirtualBox::createAppliance" />, which can then be used to import and export
3036	appliances with VirtualBox.
3037
3038	The OVF standard suggests two different physical file formats:
3039
3040	<ol>
3041	<li>If the OVF is distributed as a set of files, then @a file must be a fully qualified
3042	path name to an existing OVF descriptor file with an <tt>.ovf</tt> file extension. If
3043	this descriptor file references other files, as OVF appliances distributed as a set of
3044	files most likely do, those files must be in the same directory as the descriptor file.</li>
3045
3046	<li>If the OVF is distributed as a single file, it must be in TAR format and have the
3047	<tt>.ova</tt> file extension. This TAR file must then contain at least the OVF descriptor
3048	files and optionally other files.
3049
3050	At this time, VirtualBox does not not yet support the packed (TAR) variant; support will
3051	be added with a later version.</li>
3052	</ol>
3053
3054	<b>Importing</b> an OVF appliance into VirtualBox as instances of
3055	<link to="IMachine" /> involves the following sequence of API calls:
3056
3057	<ol>
3058	<li>Call <link to="IVirtualBox::createAppliance" />. This will create an empty IAppliance object.
3059	</li>
3060
3061	<li>On the new object, call <link to="#read" /> with the full path of the OVF file you
3062	would like to import. So long as this file is syntactically valid, this will succeed
3063	and return an instance of IAppliance that contains the parsed data from the OVF file.
3064	</li>
3065
3066	<li>Next, call <link to="#interpret" />, which analyzes the OVF data and sets up the
3067	contents of the IAppliance attributes accordingly. These can be inspected by a
3068	VirtualBox front-end such as the GUI, and the suggestions can be displayed to the
3069	user. In particular, the <link to="#virtualSystemDescriptions" /> array contains
3070	instances of <link to="IVirtualSystemDescription" /> which represent the virtual
3071	systems in the OVF, which in turn describe the virtual hardware prescribed by the
3072	OVF (network and hardware adapters, virtual disk images, memory size and so on).
3073	The GUI can then give the user the option to confirm and/or change these suggestions.
3074	</li>
3075
3076	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
3077	virtual system to override the suggestions made by the interpret() routine.
3078	</li>
3079
3080	<li>Finally, call <link to="#importMachines" /> to create virtual machines in
3081	VirtualBox as instances of <link to="IMachine" /> that match the information in the
3082	virtual system descriptions.
3083	</li>
3084	</ol>
3085
3086	<b>Exporting</b> VirtualBox machines into an OVF appliance involves the following steps:
3087
3088	<ol>
3089	<li>As with importing, first call <link to="IVirtualBox::createAppliance" /> to create
3090	an empty IAppliance object.
3091	</li>
3092
3093	<li>For each machine you would like to export, call <link to="IMachine::export" />
3094	with the IAppliance object you just created. This creates an instance of
3095	<link to="IVirtualSystemDescription" /> inside the appliance.
3096	</li>
3097
3098	<li>If desired, call <link to="IVirtualSystemDescription::setFinalValues" /> for each
3099	virtual system to override the suggestions made by the export() routine.
3100	</li>
3101
3102	<li>Finally, call <link to="#write" /> with a path specification to have the OVF
3103	file written.</li>
3104	</ol>

3107
3108	<attribute name="path" type="wstring" readonly="yes">

3120	disk information, with the information fields separated by tab (\\t) characters.
3121
3122	The caller should be prepared for additional fields being appended to
3123	this string in future versions of VirtualBox and therefore check for
3124	the number of tabs in the strings returned.

3138	"http://www.vmware.com/specifications/vmdk.html#sparse")</li>
3139
3140	<li>Reference (where to find the disk image, typically a file name; if empty,
3141	then the disk should be created on import)</li>
3142
3143	<li>Image size (optional unsigned integer indicating the size of the image,
3144	which need not necessarily be the same as the values specified above, since
3145	the image may be compressed or sparse; -1 if not specified)</li>
3146
3147	<li>Chunk size (optional unsigned integer if the image is split into chunks;
3148	presently unsupported and always -1)</li>
3149
3150	<li>Compression (optional string equalling "gzip" if the image is gzip-compressed)</li>

3336	The list below identifies the value sets that are possible depending on the
3337	<link to="VirtualSystemDescriptionType" /> enum value in the array item in aTypes[]. In each case,
3338	the array item with the same index in aOvfValues[] will contain the original value as contained
3339	in the OVF file (just for informational purposes), and the corresponding item in aVBoxValues[]
3340	will contain a suggested value to be used for VirtualBox. Depending on the description type,
3341	the aExtraConfigValues[] array item may also be used.
3342
3343	<ul>
3344	<li>
3345	"OS": the guest operating system type. There must be exactly one such array item on import. The
3346	corresponding item in aVBoxValues[] contains the suggested guest operating system for VirtualBox.
3347	This will be one of the values listed in <link to="IVirtualBox::guestOSTypes" />. The corresponding
3348	item in aOvfValues[] will contain a numerical value that described the operating system in the OVF.
3349	</li>
3350	<li>
3351	"Name": the name to give to the new virtual machine. There can be at most one such array item;
3352	if none is present on import, then an automatic name will be created from the operating system
3353	type. The correponding item im aOvfValues[] will contain the suggested virtual machine name
3354	from the OVF file, and aVBoxValues[] will contain a suggestion for a unique VirtualBox
3355	<link to="IMachine" /> name that does not exist yet.
3356	</li>
3357	<li>
3358	"Description": an arbitrary description.
3359	</li>
3360	<li>
3361	"License": the EULA section from the OVF, if present. It is the responsibility of the calling
3362	code to display such a license for agreement; the Main API does not enforce any such policy.
3363	</li>
3364	<li>
3365	Miscellaneous: reserved for future use.
3366	</li>
3367	<li>
3368	"CPU": the number of CPUs. There can be at most one such item, which will presently be ignored.
3369	</li>
3370	<li>
3371	"Memory": the amount of guest RAM, in bytes. There can be at most one such array item; if none
3372	is present on import, then VirtualBox will set a meaningful default based on the operating system
3373	type.
3374	</li>
3375	<li>
3376	"HarddiskControllerIDE": an IDE hard disk controller. There can be at most one such item. This
3377	has no value in aOvfValues[] or aVBoxValues[].
3378	The matching item in the aRefs[] array will contain an integer that items of the "Harddisk"
3379	type can use to specify which hard disk controller a virtual disk should be connected to.
3380	</li>
3381	<li>
3382	"HarddiskControllerSATA": an SATA hard disk controller. There can be at most one such item. This
3383	has no value in aOvfValues[] or aVBoxValues[].
3384	The matching item in the aRefs[] array will be used as with IDE controllers (see above).
3385	</li>
3386	<li>
3387	"HarddiskControllerSCSI": a SCSI hard disk controller. There can be at most one such item.
3388	The items in aOvfValues[] and aVBoxValues[] will either be "LsiLogic" or "BusLogic".
3389	The matching item in the aRefs[] array will be used as with IDE controllers (see above).
3390	</li>
3391	<li>
3392	"HardDiskImage": a virtual hard disk, most probably as a reference to an image file. There can be an
3393	arbitrary number of these items, one for each virtual disk image that accompanies the OVF.
3394
3395	The array item in aOvfValues[] will contain the file specification from the OVF file (without
3396	a path since the image file should be in the same location as the OVF file itself), whereas the
3397	item in aVBoxValues[] will contain a qualified path specification to where VirtualBox uses the
3398	hard disk image. This means that on import the image will be copied and converted from the
3399	"ovf" location to the "vbox" location; on export, this will be handled the other way round.
3400	On import, the target image will also be registered with VirtualBox.
3401
3402	The matching item in the aExtraConfigValues[] array must contain a string of the following
3403	format: "controller=<index>;channel=<c>"
3404	In this string, <index> must be an integer specifying the hard disk controller to connect
3405	the image to. That number must be the index of an array item with one of the hard disk controller
3406	types (HarddiskControllerSCSI, HarddiskControllerSATA, HarddiskControllerIDE).
3407	In addition, <c> must specify the channel to use on that controller. For IDE controllers,
3408	this can range from 0-3 (which VirtualBox will interpret as primary master, primary slave, secondary master and
3409	secondary slave. For SATA and SCSI controllers, the channel can range from 0-29.
3410	</li>
3411	<li>
3412	"NetworkAdapter": a network adapter. The array item in aVBoxValues[] will specify the hardware
3413	for the network adapter, whereas the array item in aExtraConfigValues[] will have a string
3414	of the "type=<X>" format, where <X> must be either "NAT" or "Bridged".
3415	</li>
3416	<li>
3417	"USBController": a USB controller. There can be at most one such item. If and only if such an
3418	item ispresent, USB support will be enabled for the new virtual machine.
3419	</li>
3420	<li>
3421	"SoundCard": a sound card. There can be at most one such item. If and only if such an item is
3422	present, sound support will be enabled for the new virtual machine. Note that the virtual
3423	machine in VirtualBox will always be presented with the standard VirtualBox soundcard, which
3424	may be different from the virtual soundcard expected by the appliance.

4007	<desc>
4008	The IMachine interface represents a virtual machine, or guest, created
4009	in VirtualBox.
4010
4011	This interface is used in two contexts. First of all, a collection of
4012	objects implementing this interface is stored in the
4013	<link to="IVirtualBox::machines"/> attribute which lists all the virtual
4014	machines that are currently registered with this VirtualBox
4015	installation. Also, once a session has been opened for the given virtual
4016	machine (e.g. the virtual machine is running), the machine object
4017	associated with the open session can be queried from the session object;
4018	see <link to="ISession"/> for details.
4019
4020	The main role of this interface is to expose the settings of the virtual
4021	machine and provide methods to change various aspects of the virtual
4022	machine's configuration. For machine objects stored in the
4023	<link to="IVirtualBox::machines"/> collection, all attributes are
4024	read-only unless explicitly stated otherwise in individual attribute
4025	and method descriptions. In order to change a machine setting, a session
4026	for this machine must be opened using one of
4027	<link to="IVirtualBox::openSession"/>,
4028	<link to="IVirtualBox::openRemoteSession"/> or
4029	<link to="IVirtualBox::openExistingSession"/> methods. After the
4030	session has been successfully opened, a mutable machine object needs to
4031	be queried from the session object and then the desired settings changes
4032	can be applied to the returned object using IMachine attributes and
4033	methods. See the <link to="ISession"/> interface description for more
4034	information about sessions.
4035
4036	Note that IMachine does not provide methods to control virtual machine
4037	execution (such as start the machine, or power it down) -- these methods
4038	are grouped in a separate interface called <link to="IConsole" />.

4047	<attribute name="accessible" type="boolean" readonly="yes">
4048	<desc>
4049	Whether this virtual machine is currently accessible or not.
4050
4051	A machine is always deemed accessible unless it is registered <i>and</i>
4052	its settings file cannot be read or parsed (either because the file itself
4053	is unavailable or has invalid XML contents).
4054
4055	Every time this property is read, the accessibility state of
4056	this machine is re-evaluated. If the returned value is @c false,
4057	the <link to="#accessError"/> property may be used to get the
4058	detailed error information describing the reason of
4059	inaccessibility, including XML error messages.
4060
4061	When the machine is inaccessible, only the following properties
4062	can be used on it:
4063	<ul>
4064	<li><link to="#parent"/></li>
4065	<li><link to="#id"/></li>
4066	<li><link to="#settingsFilePath"/></li>
4067	<li><link to="#accessible"/></li>
4068	<li><link to="#accessError"/></li>
4069	</ul>
4070
4071	An attempt to access any other property or method will return
4072	an error.
4073
4074	The only possible action you can perform on an inaccessible
4075	machine is to unregister it using the
4076	<link to="IVirtualBox::unregisterMachine"/> call (or, to check
4077	for the accessibility state once more by querying this
4078	property).
4079
4080	<note>
4081	In the current implementation, once this property returns
4082	@c true, the machine will never become inaccessible
4083	later, even if its settings file cannot be successfully
4084	read/written any more (at least, until the VirtualBox
4085	server is restarted). This limitation may be removed in
4086	future releases.

4098	machine is currently unaccessible). Otherwise, a @c null

4111	change the value of this property, the settings file will be
4112	renamed once you call <link to="#saveSettings"/> to confirm the
4113	change. The containing subdirectory will be also renamed, but

4115	itself prior to changing this property (for backward compatibility
4116	with previous API releases). The above implies the following
4117	limitations:
4118	<ul>
4119	<li>The machine name cannot be empty.</li>
4120	<li>The machine name can contain only characters that are valid
4121	file name characters according to the rules of the file
4122	system used to store VirtualBox configuration.</li>
4123	<li>You cannot have two or more machines with the same name
4124	if they use the same subdirectory for storing the machine
4125	settings files.</li>
4126	<li>You cannot change the name of the machine if it is running,
4127	or if any file in the directory containing the settings file
4128	is being used by another running machine or by any other
4129	process in the host operating system at a time when
4130	<link to="#saveSettings"/> is called.
4131	</li>
4132	</ul>
4133	If any of the above limitations are hit, <link to="#saveSettings"/>
4134	will return an appropriate error message explaining the exact
4135	reason and the changes you made to this machine will not be
4136	saved.
4137	<note>
4138	For "legacy" machines created using the
4139	<link to="IVirtualBox::createLegacyMachine"/> call,
4140	the above naming limitations do not apply because the
4141	machine name does not affect the settings file name.
4142	The settings file name remains the same as it was specified
4143	during machine creation and never changes.

4568	for changing the media while the machine is running.
4569
4570	For the IDE bus, the @a controllerPort parameter can be either
4571	@c 0 or @c 1, to specify the primary or secondary IDE controller,
4572	respectively. For each of these, @a device can then be either @c 0 or @c 1,
4573	to specify the master or the slave device, respectively. (In the
4574	default configuration of virtual machines, the secondary master is
4575	used for a CD/DVD drive.)
4576
4577	For an SATA controller, @a controllerPort must be a number ranging
4578	from @c 0 to @c 29. For a SCSI controller, @a controllerPort must
4579	be a number ranging from @c 0 to @c 15.
4580
4581	For both SCSI and SATA, the @a device parameter is unused and must
4582	be @c 0.
4583
4584	For fixed media such as hard disks, the given medium cannot be NULL. It may
4585	be NULL for removable media such as DVDs and floppies.

4587	After calling this returns successfully, a new instance of
4588	<link to="IMediumAttachment"/> will appear in the machine's list of medium
4589	attachments (<link to="IMachine::mediumAttachments"/>).

5420	This interface is used by a client of the Main API that need to
5421	be notified of events. For example, a graphical user interface
5422	can use this to learn about machine state changes so they can
5423	update the list of virtual machines without having to rely
5424	on polling.
5425
5426	Whenever relevant events occur in VirtualBox, the callbacks in
5427	objects of this interface are called. In order for this to be
5428	useful, a client needs to create its own subclass that implements
5429	this interface in which the methods for the relevant callbacks
5430	are overridden. An instance of this subclass interface can then
5431	be passed to <link to="IConsole::registerCallback" />.

5473	The @a shape buffer contains a 1-bpp (bits per pixel) AND mask
5474	followed by a 32-bpp XOR (color) mask.
5475
5476	For pointers without alpha channel the XOR mask pixels are 32
5477	bit values: (lsb)BGR0(msb). For pointers with alpha channel
5478	the XOR mask consists of (lsb)BGRA(msb) 32 bit values.
5479
5480	An AND mask is used for pointers with alpha channel, so if the
5481	callback does not support alpha, the pointer could be
5482	displayed as a normal color pointer.
5483
5484	The AND mask is a 1-bpp bitmap with byte aligned scanlines. The
5485	size of the AND mask therefore is <tt>cbAnd = (width + 7) / 8 *
5486	height</tt>. The padding bits at the end of each scanline are
5487	undefined.
5488
5489	The XOR mask follows the AND mask on the next 4-byte aligned
5490	offset: <tt>uint8_t *pXor = pAnd + (cbAnd + 3) & ~3</tt>.
5491	Bytes in the gap between the AND and the XOR mask are undefined.
5492	The XOR mask scanlines have no gap between them and the size of
5493	the XOR mask is: <tt>cXor = width * 4 * height</tt>.

6468	<method name="discardSnapshot">
6469	<desc>
6470	Starts discarding the specified snapshot asynchronously.
6471	See <link to="ISnapshot" /> for an introduction to snapshots.
6472
6473	The execution state
6474	and settings of the associated machine stored in the snapshot
6475	will be deleted. The contents of all differencing media of
6476	this snapshot will be merged with the contents of their
6477	dependent child media to keep the disks valid (in other
6478	words, all changes represented by media being discarded
6479	will be propagated to their child medium). After that, this
6480	snapshot's differencing medium will be deleted. The parent
6481	of this snapshot will become a new parent for all its child
6482	snapshots.
6483
6484	If the discarded snapshot is the current one, its parent
6485	snapshot will become a new current snapshot. The current machine
6486	state is not directly affected in this case, except that
6487	currently attached differencing media based on media
6488	of the discarded snapshot will be also merged as described
6489	above.
6490
6491	If the discarded snapshot is the first one (the root snapshot)
6492	and it has exactly one child snapshot, this child snapshot will
6493	become the first snapshot after discarding. If there are no
6494	children at all (i.e. the first snapshot is the only snapshot of
6495	the machine), both the current and the first snapshot of the
6496	machine will be set to @c null. In all other cases, the first
6497	snapshot cannot be discarded.
6498
6499	You cannot discard the snapshot if it
6500	stores <link to="MediumType_Normal">normal</link> (non-differencing)
6501	media that have differencing media based on them. Snapshots of
6502	such kind can be discarded only when every normal medium has either
6503	no children at all or exactly one child. In the former case, the normal
6504	medium simply becomes unused (i.e. not attached to any VM). In the
6505	latter case, it receives all the changes stored in the child medium,
6506	and then it replaces the child medium in the configuration of the
6507	corresponding snapshot or machine.
6508
6509	Also, you cannot discard the snapshot if it stores media
6510	(of any type) having differencing child media that belong
6511	to other machines. Such snapshots can be only discarded after
6512	you discard all snapshots of other machines containing "foreign"
6513	child disks, or detach these "foreign" child disks from machines
6514	they are attached to.
6515
6516	One particular example of the snapshot storing normal media
6517	is the first snapshot of a virtual machine that had normal media
6518	attached when taking the snapshot. Be careful when
6519	discarding such snapshots because this implicitly commits
6520	changes (made since the snapshot being discarded has been taken)
6521	to normal media (as described above), which may be not what
6522	you want.
6523
6524	The virtual machine is put to
6525	the <link to="MachineState_Discarding">Discarding</link> state until
6526	the discard operation is completed.
6527
6528	<note>
6529	The machine must not be running, otherwise the operation
6530	will fail.
6531	</note>
6532
6533	<note>
6534	Child media of all normal media of the discarded snapshot
6535	must be accessible (see <link to="IMedium::state"/>) for this
6536	operation to succeed. In particular, this means that all virtual
6537	machines, whose media are directly or indirectly based on the
6538	media of discarded snapshot, must be powered off.
6539	</note>
6540	<note>
6541	Merging medium contents can be very time and disk space
6542	consuming, if these disks are big in size and have many
6543	children. However, if the snapshot being discarded is the last
6544	(head) snapshot on the branch, the operation will be rather
6545	quick.
6546	</note>
6547	<note>
6548	Note that discarding the current snapshot
6549	will implicitly call <link to="IMachine::saveSettings"/> to
6550	make all current machine settings permanent.

6607
6608	As a result, the machine will be fully restored from the

6610	snapshot and the current machine state will be discarded.

7389	(<link to="IMediumFormat::id"/>) used in other API calls like
7390	<link to="IVirtualBox::createHardDisk"/> to refer to a particular

7411	Identifier of the default medium format used by VirtualBox.
7412
7413	The medium format set by this attribute is used by VirtualBox
7414	when the medium format was not specified explicitly. One example is
7415	<link to="IVirtualBox::createHardDisk"/> with the empty
7416	format argument. A more complex example is implicit creation of
7417	differencing media when taking a snapshot of a virtual machine:
7418	this operation will try to use a format of the parent medium first
7419	and if this format does not support differencing media the default
7420	format specified by this argument will be used.
7421
7422	The list of supported medium formats may be obtained by the

7473
7474	As opposed to <link to="ISystemProperties::remoteDisplayAuthLibrary" />,
7475	there is no per-VM setting for this, as the webservice is a global
7476	resource (if it is running). Only for this setting (for the webservice),
7477	setting this value to a literal <tt>"null"</tt> string disables authentication,

7480
7481	The initial value of this property is <tt>"VRDPAuth"</tt>,

7734	The IProgress interface is used to track and control
7735	asynchronous tasks within VirtualBox.
7736
7737	An instance of this is returned every time VirtualBox starts
7738	an asynchronous task (in other words, a separate thread) which
7739	continues to run after a method call returns. For example,
7740	<link to="IConsole::saveState" />, which saves the state of
7741	a running virtual machine, can take a long time to complete.
7742	To be able to display a progress bar, a user interface such as
7743	the VirtualBox graphical user interface can use the IProgress
7744	object returned by that method.
7745
7746	Note that IProgress is a "read-only" interface in the sense
7747	that only the VirtualBox internals behind the Main API can
7748	create and manipulate progress objects, whereas client code
7749	can only use the IProgress object to monitor a task's
7750	progress and, if <link to="#cancelable" /> is @c true,
7751	cancel the task by calling <link to="#cancel" />.
7752
7753	A task represented by IProgress consists of either one or
7754	several sub-operations that run sequentially, one by one (see
7755	<link to="#operation" /> and <link to="#operationCount" />).
7756	Every operation is identified by a number (starting from 0)
7757	and has a separate description.
7758
7759	You can find the individual percentage of completion of the current
7760	operation in <link to="#operationPercent" /> and the
7761	percentage of completion of the task as a whole
7762	in <link to="#percent" />.
7763
7764	Similarly, you can wait for the completion of a particular
7765	operation via <link to="#waitForOperationCompletion" /> or

7767	<link to="#waitForCompletion" />.

7926	<interface
7927	name="ISnapshot" extends="$unknown"
7928	uuid="1a2d0551-58a4-4107-857e-ef414fc42ffc"
7929	wsmap="managed"
7930	>
7931	<desc>
7932	The ISnapshot interface represents a snapshot of the virtual
7933	machine.
7934
7935	Together with the differencing media that are created
7936	when a snapshot is taken, a machine can be brought back to
7937	the exact state it was in when the snapshot was taken.
7938
7939	The ISnapshot interface has no methods, only attributes; snapshots
7940	are controlled through methods of the <link to="IConsole" /> interface
7941	which also manage the media associated with the snapshot.
7942	The following operations exist:
7943
7944	<ul>
7945	<li><link to="IConsole::takeSnapshot"/>: creates a new snapshot
7946	by creating new, empty differencing images for the machine's
7947	media and saving the VM settings and (if the VM is running)
7948	the current VM state in the snapshot.
7949
7950	The differencing images will then receive all data written to
7951	the machine's media, while their parent (base) images
7952	remain unmodified after the snapshot has been taken (see
7953	<link to="IMedium" /> for details about differencing images).
7954	This simplifies restoring a machine to the state of a snapshot:
7955	only the differencing images need to be deleted.
7956
7957	The current machine state is not changed by taking a snapshot.
7958	If the machine is running, it will resume execution after the
7959	snapshot has been taken.
7960	</li>
7961
7962	<li><link to="IConsole::discardCurrentState"/>: this goes back to
7963	a previous snapshot. This resets the machine's state to that of
7964	the previous snapshot by deleting the differencing image of each
7965	of the machine's media and setting the machine's settings
7966	and state to the state that was saved in the snapshot (if any).
7967
7968	This destroys the machine's current state.
7969	</li>
7970
7971	<li><link to="IConsole::discardSnapshot"/>: deletes a snapshot
7972	without affecting the current machine state.
7973
7974	This does not change the machine, but instead frees the resources
7975	allocated when the snapshot was taken: the settings and machine state
7976	is deleted (if any), and the snapshot's differencing image for each
7977	of the machine's media gets merged with its parent image.
7978
7979	Neither the current machine state nor other snapshots are affected
7980	by this operation, except that parent disk images will be modified
7981	to contain the disk data associated with the snapshot being deleted.
7982	</li>
7983
7984	<li><link to="IConsole::discardCurrentSnapshotAndState"/>:
7985	this completely reverts the virtual machine to the state it was in
7986	before the current snapshot has been taken. Effectively, this goes
7987	back to the state before the current snapshot, which might be
7988	an earlier snapshot.
7989
7990	The current state, as well as the current snapshot, are lost.
7991	</li>
7992	</ul>
7993
7994	Each snapshot contains the settings of the virtual machine (hardware
7995	configuration etc.). In addition, if the machine was running when the
7996	snapshot was taken (<link to="IMachine::state"/> is <link to="MachineState_Running"/>),
7997	the current VM state is saved in the snapshot (similarly to what happens
7998	when a VM's state is saved). The snapshot is then said to
7999	be <i>online</i> because when restoring it, the VM will be running.
8000
8001	If the machine is saved (<link to="MachineState_Saved"/>), the snapshot
8002	receives a copy of the execution state file (<link to="IMachine::stateFilePath"/>).
8003
8004	Otherwise, if the machine was not running (<link to="MachineState_PoweredOff"/>
8005	or <link to="MachineState_Aborted"/>), the snapshot is <i>offline</i>;
8006	it then contains a so-called "zero execution state", representing a
8007	machine that is powered off.
8008
8009	<h3>Snapshot branches and the "current" snapshot</h3>
8010
8011	Snapshots can be chained, whereby every next snapshot is based on the
8012	previous one. This chaining is related to medium branching
8013	(see the <link to="IMedium"/> description) in that every time
8014	a new snapshot is created, a new differencing medium is implicitly
8015	created for all normal media attached to the machine.
8016
8017	Each virtual machine has a "current snapshot", identified by
8018	<link to="IMachine::currentSnapshot"/>. Presently, this is always set
8019	to the last snapshot in the chain. In a future version of VirtualBox,
8020	it will be possible to reset a machine's current state to that of an
8021	earlier snapshot without discarding the current state so that it will be
8022	possible to create alternative snapshot paths in a snapshot tree.
8023
8024	In the current implementation, multiple snapshot branches within one
8025	virtual machine are not allowed. Every machine has a single branch,
8026	and <link to="IConsole::takeSnapshot"/> operation adds a new
8027	snapshot to the top of that branch.

8268	<desc>
8269	The IMedium interface represents virtual storage for a machine's
8270	hard disks, CD/DVD or floppy drives. It will typically represent
8271	a disk image on the host, for example a VDI or VMDK file representing
8272	a virtual hard disk, or an ISO or RAW file representing virtual
8273	removable media, but can also point to a network location (e.g.
8274	for iSCSI targets).
8275
8276	Instances of IMedium are connected to virtual machines by way of
8277	medium attachments (see <link to="IMediumAttachment" />), which link
8278	the storage medium to a particular device slot of a storage controller
8279	of the virtual machine.
8280	In the VirtualBox API, virtual storage is therefore always represented
8281	by the following chain of object links:
8282
8283	<ul>
8284	<li><link to="IMachine::storageControllers"/> contains an array of
8285	storage controllers (IDE, SATA, SCSI or a floppy controller;
8286	these are instances of <link to="IStorageController"/>).</li>
8287	<li><link to="IMachine::mediumAttachments"/> contains an array of
8288	medium attachments (instances of <link to="IMediumAttachment"/>),
8289	each containing the name of a storage controller from the above
8290	array, a port/device specification, and an instance of
8291	IMedium representing the medium storage (image file). For removable
8292	media, the storage medium is optional; a medium attachment with no
8293	medium represents a CD/DVD or floppy drive with no medium inserted.
8294	By contrast, hard disk attachments will always have an IMedium
8295	object attached.</li>
8296	<li>Each IMedium in turn points to a storage unit (such as a file on the host
8297	computer or a network resource) that holds actual data. The location of
8298	the storage unit is represented by the <link to="#location"/> attribute.
8299	The value of this attribute is medium type dependent.</li>
8300	</ul>
8301
8302	Existing media are opened using the following methods, depending on the
8303	media type:
8304	<ul>
8305	<li><link to="IVirtualBox::openHardDisk"/></li>
8306	<li><link to="IVirtualBox::openDVDImage"/></li>
8307	<li><link to="IVirtualBox::openFloppyImage"/></li>
8308	</ul>
8309
8310	New hard disk media can be created with the VirtualBox API using the
8311	<link to="IVirtualBox::createHardDisk"/> method.
8312
8313	CD/DVD and floppy images (ISO and RAW files) are usually created outside
8314	VirtualBox, e.g. by storing a copy of the real medium of the corresponding
8315	type in a regular file.
8316
8317	Only for CD/DVDs and floppies, an IMedium instance can also represent a host
8318	drive; in that case the <link to="#id" /> attribute contains the UUID of
8319	one of the drives in <link to="IHost::DVDDrives" /> or <link to="IHost::floppyDrives" />.
8320
8321	<h3>Known media</h3>
8322
8323	When an existing medium is opened for the first time, it is automatically
8324	remembered by the given VirtualBox installation or, in other words, becomes
8325	a <i>known medium</i>. Known media are stored in the media
8326	registry transparently maintained by VirtualBox and stored in settings
8327	files so that this registry is preserved when VirtualBox is not running.
8328
8329	Newly created virtual media are remembered only when the associated
8330	storage unit is actually created.
8331
8332	All known media can be enumerated using
8333	<link to="IVirtualBox::hardDisks"/>,
8334	<link to="IVirtualBox::DVDImages"/> and
8335	<link to="IVirtualBox::floppyImages"/> attributes. Individual media can be
8336	quickly found by UUID using <link to="IVirtualBox::getHardDisk"/>
8337	and similar methods or by location using
8338	<link to="IVirtualBox::findHardDisk"/> and similar methods.
8339
8340	Only known media can be attached to virtual machines.
8341
8342	Removing known media from the media registry is performed when the given
8343	medium is closed using the <link to="#close"/> method or when its
8344	associated storage unit is deleted.
8345
8346	<h3>Accessibility checks</h3>
8347
8348	The given medium (with the created storage unit) is considered to be
8349	<i>accessible</i> when its storage unit can be read. In that case, the
8350	<link to="#state"/> attribute has a value of "Created".
8351	When the storage unit cannot be read (for example, because it is located on
8352	a disconnected network resource, or was accidentally deleted outside VirtualBox),
8353	the medium is considered to be <i>inaccessible</i>, which is indicated by the
8354	"Inaccessible" state. The exact reason why the medium is inaccessible can be
8355	obtained by reading the <link to="#lastAccessError"/> attribute.
8356
8357	A new accessibility check is performed each time the <link to="#state"/>
8358	attribute is read. This check may take long time (several seconds or even
8359	minutes, depending on the storage unit location and format), and will
8360	block the calling thread until finished. For this reason, it is recommended
8361	to never read this attribute on the main UI thread to avoid making the UI
8362	unresponsive.
8363
8364	Note that when VirtualBox starts up (e.g. the VirtualBox object gets
8365	created for the first time), all known media are in the
8366	<link to="MediumState_Inaccessible"/> state but the value of the <link
8367	to="#lastAccessError"/> attribute is an empty string because no actual
8368	accessibility check is made on startup. This is done to make the
8369	VirtualBox object ready for serving requests as
8370	fast as possible and let the end-user application decide if it needs to
8371	check media accessibility right away or not.
8372
8373	<h3>Hard disk types</h3>
8374
8375	There are three types of hard disk images (see <link to="MediumType" />):
8376	"normal", "immutable" and "writethrough", represented by the
8377	<link to="#type"/> attribute. The type of the hard disk defines how the
8378	hard disk is attached to a virtual machine and what happens when a
8379	<link to="ISnapshot">snapshot</link> of the virtual machine with the
8380	attached hard disk is taken.
8381
8382	All hard disks can be also divided in two groups: <i>base</i> hard
8383	disks and <i>differencing</i> hard disks. A base hard disk contains all
8384	sectors of the hard disk data in its own storage and therefore can be
8385	used independently. On the contrary, a differencing hard disk is a
8386	"delta" to some other disk and contains only those sectors which differ
8387	from that other disk, which is then called a <i>parent</i>. The differencing
8388	hard disk is said to be <i>linked to</i> that parent.
8389	The parent may be itself a differencing image, thus forming a chain of
8390	linked hard disks. The last element in that chain
8391	must always be a base medium. Note that several differencing
8392	hard disks may be linked to the same parent hard disk.
8393
8394	Differencing hard disks can be distinguished from base hard disks by
8395	querying the <link to="#parent"/> attribute: base hard disks do not have
8396	parents they would depend on, so the value of this attribute is always
8397	@c null for them. Using this attribute, it is possible to walk up
8398	the hard disk tree (from the child hard disk to its parent). It is also
8399	possible to walk down the tree using the <link to="#children"/>
8400	attribute.
8401
8402	Note that the type of all differencing hard disks is
8403	<link to="MediumType_Normal" />; all other values are
8404	meaningless for them. Base hard disks may be of any type.
8405
8406	<h3>Creating hard disks</h3>
8407
8408	New base hard disks are created using
8409	<link to="IVirtualBox::createHardDisk"/>. Existing hard disks are
8410	opened using <link to="IVirtualBox::openHardDisk"/>. Differencing hard
8411	disks are usually implicitly created by VirtualBox when needed but may
8412	also be created explicitly using <link to="#createDiffStorage"/>.
8413
8414	After the hard disk is successfully created (including the storage unit)
8415	or opened, it becomes a known hard disk (remembered in the internal media
8416	registry). Known hard disks can be attached to a virtual machine, accessed
8417	through <link to="IVirtualBox::getHardDisk"/> and
8418	<link to="IVirtualBox::findHardDisk"/> methods or enumerated using the
8419	<link to="IVirtualBox::hardDisks"/> array (only for base hard disks).
8420
8421	The following methods, besides <link to="IMedium::close"/>,
8422	automatically remove the hard disk from the media registry:
8423	<ul>
8424	<li><link to="#deleteStorage"/></li>
8425	<li><link to="#mergeTo"/></li>
8426	</ul>
8427
8428	If the storage unit of the hard disk is a regular file in the host's
8429	file system then the rules stated in the description of the
8430	<link to="IMedium::location"/> attribute apply when setting its value. In
8431	addition, a plain file name without any path may be given, in which case
8432	the <link to="ISystemProperties::defaultHardDiskFolder"> default hard disk
8433	folder</link> will be prepended to it.
8434
8435	<h4>Automatic composition of the file name part</h4>
8436
8437	Another extension to the <link to="IMedium::location"/> attribute is that
8438	there is a possibility to cause VirtualBox to compose a unique value for
8439	the file name part of the location using the UUID of the hard disk. This
8440	applies only to hard disks in <link to="MediumState_NotCreated"/> state,
8441	e.g. before the storage unit is created, and works as follows. You set the
8442	value of the <link to="IMedium::location"/> attribute to a location
8443	specification which only contains the path specification but not the file
8444	name part and ends with either a forward slash or a backslash character.
8445	In response, VirtualBox will generate a new UUID for the hard disk and
8446	compose the file name using the following pattern:
8447	<pre>
8448	<path>/{<uuid>}.<ext>
8449	</pre>
8450	where <tt><path></tt> is the supplied path specification,
8451	<tt><uuid></tt> is the newly generated UUID and <tt><ext></tt>
8452	is the default extension for the storage format of this hard disk. After
8453	that, you may call any of the methods that create a new hard disk storage
8454	unit and they will use the generated UUID and file name.
8455
8456	<h3>Attaching Hard Disks</h3>
8457
8458	Hard disks are attached to virtual machines using the
8459	<link to="IMachine::attachDevice"/> method and detached using the
8460	<link to="IMachine::detachDevice"/> method. Depending on their
8461	<link to="#type"/>, hard disks are attached either
8462	<i>directly</i> or <i>indirectly</i>.
8463
8464	When a hard disk is being attached directly, it is associated with the
8465	virtual machine and used for hard disk operations when the machine is
8466	running. When a hard disk is being attached indirectly, a new differencing
8467	hard disk linked to it is implicitly created and this differencing hard
8468	disk is associated with the machine and used for hard disk operations.
8469	This also means that if <link to="IMachine::attachDevice"/> performs
8470	a direct attachment then the same hard disk will be returned in response
8471	to the subsequent <link to="IMachine::getMedium"/> call; however if
8472	an indirect attachment is performed then
8473	<link to="IMachine::getMedium"/> will return the implicitly created
8474	differencing hard disk, not the original one passed to <link
8475	to="IMachine::attachDevice"/>. In detail:
8476
8477	<ul>
8478	<li><b>Normal base</b> hard disks that do not have children (i.e.
8479	differencing hard disks linked to them) and that are not already
8480	attached to virtual machines in snapshots are attached <b>directly</b>.
8481	Otherwise, they are attached <b>indirectly</b> because having
8482	dependent children or being part of the snapshot makes it impossible
8483	to modify hard disk contents without breaking the integrity of the
8484	dependent party. The <link to="#readOnly"/> attribute allows to
8485	quickly determine the kind of the attachment for the given hard
8486	disk. Note that if a normal base hard disk is to be indirectly
8487	attached to a virtual machine with snapshots then a special
8488	procedure called <i>smart attachment</i> is performed (see below).</li>
8489	<li><b>Normal differencing</b> hard disks are like normal base hard disks:
8490	they are attached <b>directly</b> if they do not have children and are
8491	not attached to virtual machines in snapshots, and <b>indirectly</b>
8492	otherwise. Note that the smart attachment procedure is never performed
8493	for differencing hard disks.</li>
8494	<li><b>Immutable</b> hard disks are always attached <b>indirectly</b> because
8495	they are designed to be non-writable. If an immutable hard disk is
8496	attached to a virtual machine with snapshots then a special
8497	procedure called smart attachment is performed (see below).</li>
8498	<li><b>Writethrough</b> hard disks are always attached <b>directly</b>,
8499	also as designed. This also means that writethrough hard disks cannot
8500	have other hard disks linked to them at all.</li>
8501	</ul>
8502
8503	Note that the same hard disk, regardless of its type, may be attached to
8504	more than one virtual machine at a time. In this case, the machine that is
8505	started first gains exclusive access to the hard disk and attempts to
8506	start other machines having this hard disk attached will fail until the
8507	first machine is powered down.
8508
8509	Detaching hard disks is performed in a <i>deferred</i> fashion. This means
8510	that the given hard disk remains associated with the given machine after a
8511	successful <link to="IMachine::detachDevice"/> call until
8512	<link to="IMachine::saveSettings"/> is called to save all changes to
8513	machine settings to disk. This deferring is necessary to guarantee that
8514	the hard disk configuration may be restored at any time by a call to
8515	<link to="IMachine::discardSettings"/> before the settings
8516	are saved (committed).
8517
8518	Note that if <link to="IMachine::discardSettings"/> is called after
8519	indirectly attaching some hard disks to the machine but before a call to
8520	<link to="IMachine::saveSettings"/> is made, it will implicitly delete
8521	all differencing hard disks implicitly created by
8522	<link to="IMachine::attachDevice"/> for these indirect attachments.
8523	Such implicitly created hard disks will also be immediately deleted when
8524	detached explicitly using the <link to="IMachine::detachDevice"/>
8525	call if it is made before <link to="IMachine::saveSettings"/>. This
8526	implicit deletion is safe because newly created differencing hard
8527	disks do not contain any user data.
8528
8529	However, keep in mind that detaching differencing hard disks that were
8530	implicitly created by <link to="IMachine::attachDevice"/>
8531	before the last <link to="IMachine::saveSettings"/> call will
8532	<b>not</b> implicitly delete them as they may already contain some data
8533	(for example, as a result of virtual machine execution). If these hard
8534	disks are no more necessary, the caller can always delete them explicitly
8535	using <link to="#deleteStorage"/> after they are actually de-associated
8536	from this machine by the <link to="IMachine::saveSettings"/> call.
8537
8538	<h3>Smart Attachment</h3>
8539
8540	When normal base or immutable hard disks are indirectly attached to a
8541	virtual machine then some additional steps are performed to make sure the
8542	virtual machine will have the most recent "view" of the hard disk being
8543	attached. These steps include walking through the machine's snapshots
8544	starting from the current one and going through ancestors up to the first
8545	snapshot. Hard disks attached to the virtual machine in all
8546	of the encountered snapshots are checked whether they are descendants of
8547	the given normal base or immutable hard disk. The first found child (which
8548	is the differencing hard disk) will be used instead of the normal base or
8549	immutable hard disk as a parent for creating a new differencing hard disk
8550	that will be actually attached to the machine. And only if no descendants
8551	are found or if the virtual machine does not have any snapshots then the
8552	normal base or immutable hard disk will be used itself as a parent for
8553	this differencing hard disk.
8554
8555	It is easier to explain what smart attachment does using the
8556	following example:
8557	<pre>
8558	BEFORE attaching B.vdi: AFTER attaching B.vdi:
8559
8560	Snapshot 1 (B.vdi) Snapshot 1 (B.vdi)
8561	Snapshot 2 (D1->B.vdi) Snapshot 2 (D1->B.vdi)
8562	Snapshot 3 (D2->D1.vdi) Snapshot 3 (D2->D1.vdi)
8563	Snapshot 4 (none) Snapshot 4 (none)
8564	CurState (none) CurState (D3->D2.vdi)
8565
8566	NOT
8567	...
8568	CurState (D3->B.vdi)
8569	</pre>
8570	The first column is the virtual machine configuration before the base hard
8571	disk <tt>B.vdi</tt> is attached, the second column shows the machine after
8572	this hard disk is attached. Constructs like <tt>D1->B.vdi</tt> and similar
8573	mean that the hard disk that is actually attached to the machine is a
8574	differencing hard disk, <tt>D1.vdi</tt>, which is linked to (based on)
8575	another hard disk, <tt>B.vdi</tt>.
8576
8577	As we can see from the example, the hard disk <tt>B.vdi</tt> was detached
8578	from the machine before taking Snapshot 4. Later, after Snapshot 4 was
8579	taken, the user decides to attach <tt>B.vdi</tt> again. <tt>B.vdi</tt> has
8580	dependent child hard disks (<tt>D1.vdi</tt>, <tt>D2.vdi</tt>), therefore
8581	it cannot be attached directly and needs an indirect attachment (i.e.
8582	implicit creation of a new differencing hard disk). Due to the smart
8583	attachment procedure, the new differencing hard disk
8584	(<tt>D3.vdi</tt>) will be based on <tt>D2.vdi</tt>, not on
8585	<tt>B.vdi</tt> itself, since <tt>D2.vdi</tt> is the most recent view of
8586	<tt>B.vdi</tt> existing for this snapshot branch of the given virtual
8587	machine.
8588
8589	Note that if there is more than one descendant hard disk of the given base
8590	hard disk found in a snapshot, and there is an exact device, channel and
8591	bus match, then this exact match will be used. Otherwise, the youngest
8592	descendant will be picked up.
8593
8594	There is one more important aspect of the smart attachment procedure which
8595	is not related to snapshots at all. Before walking through the snapshots
8596	as described above, the backup copy of the current list of hard disk
8597	attachment is searched for descendants. This backup copy is created when
8598	the hard disk configuration is changed for the first time after the last
8599	<link to="IMachine::saveSettings"/> call and used by
8600	<link to="IMachine::discardSettings"/> to undo the recent hard disk
8601	changes. When such a descendant is found in this backup copy, it will be
8602	simply re-attached back, without creating a new differencing hard disk for
8603	it. This optimization is necessary to make it possible to re-attach the
8604	base or immutable hard disk to a different bus, channel or device slot
8605	without losing the contents of the differencing hard disk actually
8606	attached to the machine in place of it.
8607	</desc>
8608
8609	<attribute name="id" type="uuid" mod="string" readonly="yes">
8610	<desc>
8611	UUID of the medium. For a newly created medium, this value is a randomly
8612	generated UUID.
8613
8614	<note>
8615	For media in one of MediumState_NotCreated, MediumState_Creating or
8616	MediumState_Deleting states, the value of this property is undefined
8617	and will most likely be an empty UUID.

8628	attempt to get or set this attribute's value.

8632	(last known) value when <link to="#state"/> is <link

8634	to="MediumState_LockedWrite"/> because the value of this attribute is
8635	stored within the storage unit itself. Also note that changing the
8636	attribute value is not possible in such case, as well as when the
8637	medium is the <link to="MediumState_LockedRead"/> state.

8643	<desc>
8644	Current medium state. Inspect <link to="MediumState"/> values for details.
8645
8646	Reading this attribute may take a long time because an accessibility
8647	check of the storage unit is performed each time the attribute is read.
8648	This check may cause a significant delay if the storage unit of the
8649	given medium is, for example, a file located on a network share which is
8650	not currently accessible due to connectivity problems -- the call will
8651	not return until a timeout interval defined by the host OS for this
8652	operation expires.
8653
8654	If the last known state of the medium is <link to="MediumState_Created"/>
8655	and the accessibility check fails then the state would be set to
8656	<link to="MediumState_Inaccessible"/> and <link to="#lastAccessError"/>
8657	may be used to get more details about the failure. If the state of the
8658	medium is <link to="MediumState_LockedRead"/> or
8659	<link to="MediumState_LockedWrite"/> then it remains the same, and a
8660	non-empty value of <link to="#lastAccessError"/> will indicate a failed
8661	accessibility check in this case.
8662
8663	Note that not all medium states are applicable to all medium types.

8668	<desc>
8669	Location of the storage unit holding medium data.
8670
8671	The format of the location string is medium type specific. For medium
8672	types using regular files in a host's file system, the location
8673	string is the full file name.
8674
8675	Some medium types may support changing the storage unit location by
8676	simply changing the value of this property. If this operation is not
8677	supported, the implementation will return E_NOTIMPL in attempt to set
8678	this attribute's value.
8679
8680	When setting a value of the location attribute which is a regular file
8681	in the host's file system, the given file name may be either relative to
8682	the <link to="IVirtualBox::homeFolder">VirtualBox home folder</link> or
8683	absolute. Note that if the given location specification does not contain
8684	the file extension part then a proper default extension will be

8800	this hard disk such as its child hard disks or snapshots of virtual
8801	machines where this hard disk is attached to these machines. If there

8805	The value of this attribute can be used to determine the kind of the

8929	The read lock is shared: many clients can simultaneously lock the

8931	<link to="#lockWrite"/>) in which case an error is returned.
8932
8933	When the medium is locked for reading, it cannot be modified
8934	from within VirtualBox. This means that any method that changes
8935	the properties of this medium or contents of the storage unit
8936	will return an error (unless explicitly stated otherwise) and
8937	that an attempt to start a virtual machine that wants to modify

8940	When the virtual machine is started up, it locks for reading all
8941	media it uses in read-only mode. If some medium cannot be locked
8942	for reading, the startup procedure will fail.
8943
8944	The medium locked for reading must be unlocked using the <link

8946	can be nested and must be followed by the same number of paired

9340	<method name="mergeTo">
9341	<desc>
9342	Starts merging the contents of this hard disk and all intermediate
9343	differencing hard disks in the chain to the given target hard disk.
9344
9345	The target hard disk must be either a descendant of this hard disk or
9346	its ancestor (otherwise this method will immediately return a failure).
9347	It follows that there are two logical directions of the merge operation:
9348	from ancestor to descendant (<i>forward merge</i>) and from descendant to
9349	ancestor (<i>backward merge</i>). Let us consider the following hard disk
9350	chain:
9351
9352	<pre>Base <- Diff_1 <- Diff_2</pre>
9353
9354	Here, calling this method on the <tt>Base</tt> hard disk object with
9355	<tt>Diff_2</tt> as an argument will be a forward merge; calling it on
9356	<tt>Diff_2</tt> with <tt>Base</tt> as an argument will be a backward
9357	merge. Note that in both cases the contents of the resulting hard disk
9358	will be the same, the only difference is the hard disk object that takes
9359	the result of the merge operation. In case of the forward merge in the
9360	above example, the result will be written to <tt>Diff_2</tt>; in case of
9361	the backward merge, the result will be written to <tt>Base</tt>. In
9362	other words, the result of the operation is always stored in the target
9363	hard disk.
9364
9365	Upon successful operation completion, the storage units of all hard
9366	disks in the chain between this (source) hard disk and the target hard
9367	disk, including the source hard disk itself, will be automatically
9368	deleted and the relevant hard disk objects (including this hard disk)
9369	will become uninitialized. This means that any attempt to call any of
9370	their methods or attributes will fail with the
9371	<tt>"Object not ready" (E_ACCESSDENIED)</tt> error. Applied to the above
9372	example, the forward merge of <tt>Base</tt> to <tt>Diff_2</tt> will
9373	delete and uninitialize both <tt>Base</tt> and <tt>Diff_1</tt> hard
9374	disks. Note that <tt>Diff_2</tt> in this case will become a base hard
9375	disk itself since it will no longer be based on any other hard disk.
9376
9377	Considering the above, all of the following conditions must be met in
9378	order for the merge operation to succeed:
9379	<ul>
9380	<li>
9381	Neither this (source) hard disk nor any intermediate
9382	differencing hard disk in the chain between it and the target
9383	hard disk is attached to any virtual machine.
9384	</li>
9385	<li>
9386	Neither the source hard disk nor the target hard disk is an
9387	<link to="MediumType_Immutable"/> hard disk.
9388	</li>
9389	<li>
9390	The part of the hard disk tree from the source hard disk to the
9391	target hard disk is a linear chain, i.e. all hard disks in this
9392	chain have exactly one child which is the next hard disk in this
9393	chain. The only exception from this rule is the target hard disk in
9394	the forward merge operation; it is allowed to have any number of
9395	child hard disks because the merge operation will hot change its
9396	logical contents (as it is seen by the guest OS or by children).
9397	</li>
9398	<li>
9399	None of the involved hard disks are in
9400	<link to="MediumState_LockedRead"/> or
9401	<link to="MediumState_LockedWrite"/> state.
9402	</li>
9403	</ul>
9404
9405	<note>
9406	This (source) hard disk and all intermediates will be placed to <link
9407	to="MediumState_Deleting"/> state and the target hard disk will be
9408	placed to <link to="MediumState_LockedWrite"/> state and for the
9409	duration of this operation.

9430	big enough to hold the data or else the copy will be partial). Upon
9431	successful completion, the cloned hard disk will contain exactly the
9432	same sector data as the hard disk being cloned, except that in the
9433	first case a new UUID for the clone will be randomly generated, and in
9434	the second case the UUID will remain unchanged.
9435
9436	The @a parent argument defines which hard disk will be the parent
9437	of the clone. Passing a @c null reference indicates that the clone will
9438	be a base image, i.e. completely independent. It is possible to specify

10100
10101	There are two modes of working with the video buffer of the virtual
10102	machine. The <i>indirect</i> mode implies that the IFramebuffer
10103	implementation allocates a memory buffer for the requested display mode
10104	and provides it to the virtual machine. In <i>direct</i> mode, the
10105	IFramebuffer implementation uses the memory buffer allocated and owned
10106	by the virtual machine. This buffer represents the video memory of the
10107	emulated video adapter (so called <i>guest VRAM</i>). The direct mode is
10108	usually faster because the implementation gets a raw pointer to the
10109	guest VRAM buffer which it can directly use for visualizing the contents
10110	of the virtual display, as opposed to the indirect mode where the
10111	contents of guest VRAM are copied to the memory buffer provided by
10112	the implementation every time a display update occurs.
10113
10114	It is important to note that the direct mode is really fast only when
10115	the implementation uses the given guest VRAM buffer directly, for
10116	example, by blitting it to the window representing the virtual machine's
10117	display, which saves at least one copy operation comparing to the
10118	indirect mode. However, using the guest VRAM buffer directly is not
10119	always possible: the format and the color depth of this buffer may be
10120	not supported by the target window, or it may be unknown (opaque) as in
10121	case of text or non-linear multi-plane VGA video modes. In this case,
10122	the indirect mode (that is always available) should be used as a
10123	fallback: when the guest VRAM contents are copied to the
10124	implementation-provided memory buffer, color and format conversion is
10125	done automatically by the underlying code.
10126
10127	The @a pixelFormat parameter defines whether the direct mode is
10128	available or not. If @a pixelFormat is <link
10129	to="FramebufferPixelFormat_Opaque"/> then direct access to the guest
10130	VRAM buffer is not available -- the @a VRAM, @a bitsPerPixel and
10131	@a bytesPerLine parameters must be ignored and the implementation must use
10132	the indirect mode (where it provides its own buffer in one of the
10133	supported formats). In all other cases, @a pixelFormat together with
10134	@a bitsPerPixel and @a bytesPerLine define the format of the video memory
10135	buffer pointed to by the @a VRAM parameter and the implementation is
10136	free to choose which mode to use. To indicate that this frame buffer uses
10137	the direct mode, the implementation of the <link to="#usesGuestVRAM"/>
10138	attribute must return @c true and <link to="#address"/> must
10139	return exactly the same address that is passed in the @a VRAM parameter
10140	of this method; otherwise it is assumed that the indirect strategy is
10141	chosen.
10142
10143	The @a width and @a height parameters represent the size of the
10144	requested display mode in both modes. In case of indirect mode, the
10145	provided memory buffer should be big enough to store data of the given
10146	display mode. In case of direct mode, it is guaranteed that the given
10147	@a VRAM buffer contains enough space to represent the display mode of the
10148	given size. Note that this frame buffer's <link to="#width"/> and <link
10149	to="#height"/> attributes must return exactly the same values as
10150	passed to this method after the resize is completed (see below).
10151
10152	The @a finished output parameter determines if the implementation has
10153	finished resizing the frame buffer or not. If, for some reason, the
10154	resize cannot be finished immediately during this call, @a finished
10155	must be set to @c false, and the implementation must call
10156	<link to="IDisplay::resizeCompleted"/> after it has returned from
10157	this method as soon as possible. If @a finished is @c false, the
10158	machine will not call any frame buffer methods until
10159	<link to="IDisplay::resizeCompleted"/> is called.
10160
10161	Note that if the direct mode is chosen, the <link to="#bitsPerPixel"/>,
10162	<link to="#bytesPerLine"/> and <link to="#pixelFormat"/> attributes of
10163	this frame buffer must return exactly the same values as specified in the
10164	parameters of this method, after the resize is completed. If the
10165	indirect mode is chosen, these attributes must return values describing
10166	the format of the implementation's own memory buffer <link
10167	to="#address"/> points to. Note also that the <link to="#bitsPerPixel"/>
10168	value must always correlate with <link to="#pixelFormat"/>. Note that
10169	the <link to="#pixelFormat"/> attribute must never return <link
10170	to="FramebufferPixelFormat_Opaque"/> regardless of the selected mode.
10171
10172	<note>
10173	This method is called by the IDisplay object under the

10788	The ISerialPort interface represents the virtual serial port device.

10791	inside the virtual machine. This device communicates to the real
10792	serial port hardware in one of two modes: host pipe or host device.
10793
10794	In host pipe mode, the #path attribute specifies the path to the pipe on
10795	the host computer that represents a serial port. The #server attribute
10796	determines if this pipe is created by the virtual machine process at
10797	machine startup or it must already exist before starting machine
10798	execution.
10799
10800	In host device mode, the #path attribute specifies the name of the
10801	serial port device on the host computer.
10802
10803	There is also a third communication mode: the disconnected mode. In this
10804	mode, the guest OS running inside the virtual machine will be able to
10805	detect the serial port, but all port write operations will be discarded

11294	<desc>
11295	The IUSBDeviceFilter interface represents an USB device filter used
11296	to perform actions on a group of USB devices.
11297
11298	This type of filters is used by running virtual machines to
11299	automatically capture selected USB devices once they are physically
11300	attached to the host computer.
11301
11302	A USB device is matched to the given device filter if and only if all
11303	attributes of the device match the corresponding attributes of the
11304	filter (that is, attributes are joined together using the logical AND
11305	operation). On the other hand, all together, filters in the list of
11306	filters carry the semantics of the logical OR operation. So if it is
11307	desirable to create a match like "this vendor id OR this product id",
11308	one needs to create two filters and specify "any match" (see below)
11309	for unused attributes.
11310
11311	All filter attributes used for matching are strings. Each string
11312	is an expression representing a set of values of the corresponding
11313	device attribute, that will match the given filter. Currently, the
11314	following filtering expressions are supported:
11315
11316	<ul>
11317	<li><i>Interval filters</i>. Used to specify valid intervals for
11318	integer device attributes (Vendor ID, Product ID and Revision).
11319	The format of the string is:
11320
11321	<tt>int:((m)\|([m]-[n]))(,(m)\|([m]-[n]))*</tt>
11322
11323	where <tt>m</tt> and <tt>n</tt> are integer numbers, either in octal
11324	(starting from <tt>0</tt>), hexadecimal (starting from <tt>0x</tt>)
11325	or decimal (otherwise) form, so that <tt>m < n</tt>. If <tt>m</tt>
11326	is omitted before a dash (<tt>-</tt>), the minimum possible integer
11327	is assumed; if <tt>n</tt> is omitted after a dash, the maximum

11330	<li><i>Boolean filters</i>. Used to specify acceptable values for

11333	<tt>true\|false\|yes\|no\|0\|1</tt>
11334
11335	</li>
11336	<li><i>Exact match</i>. Used to specify a single value for the given
11337	device attribute. Any string that doesn't start with <tt>int:</tt>
11338	represents the exact match. String device attributes are compared to
11339	this string including case of symbols. Integer attributes are first
11340	converted to a string (see individual filter attributes) and then
11341	compared ignoring case.
11342
11343	</li>
11344	<li><i>Any match</i>. Any value of the corresponding device attribute
11345	will match the given filter. An empty or @c null string is
11346	used to construct this type of filtering expressions.
11347
11348	</li>
11349	</ul>
11350
11351	<note>
11352	On the Windows host platform, interval filters are not currently
11353	available. Also all string filter attributes
11354	(<link to="#manufacturer"/>, <link to="#product"/>,
11355	<link to="#serialNumber"/>) are ignored, so they behave as
11356	<i>any match</i> no matter what string expression is specified.

11464	USB device state. This enumeration represents all possible states
11465	of the USB device physically attached to the host computer regarding
11466	its state on the host computer and availability to guest computers
11467	(all currently running virtual machines).
11468
11469	Once a supported USB device is attached to the host, global USB
11470	filters (<link to="IHost::USBDeviceFilters"/>) are activated. They can
11471	either ignore the device, or put it to USBDeviceState_Held state, or do
11472	nothing. Unless the device is ignored by global filters, filters of all
11473	currently running guests (<link to="IUSBController::deviceFilters"/>) are
11474	activated that can put it to USBDeviceState_Captured state.
11475
11476	If the device was ignored by global filters, or didn't match
11477	any filters at all (including guest ones), it is handled by the host
11478	in a normal way. In this case, the device state is determined by
11479	the host and can be one of USBDeviceState_Unavailable, USBDeviceState_Busy
11480	or USBDeviceState_Available, depending on the current device usage.
11481
11482	Besides auto-capturing based on filters, the device can be manually
11483	captured by guests (<link to="IConsole::attachUSBDevice"/>) if its
11484	state is USBDeviceState_Busy, USBDeviceState_Available or
11485	USBDeviceState_Held.
11486
11487	<note>
11488	Due to differences in USB stack implementations in Linux and Win32,
11489	states USBDeviceState_Busy and USBDeviceState_vailable are applicable
11490	only to the Linux version of the product. This also means that (<link

11784	<desc>
11785	The ISharedFolder interface represents a folder in the host computer's
11786	file system accessible from the guest OS running inside a virtual
11787	machine using an associated logical name.
11788
11789	There are three types of shared folders:
11790	<ul>
11791	<li><i>Global</i> (<link to="IVirtualBox::sharedFolders"/>), shared
11792	folders available to all virtual machines.</li>
11793	<li><i>Permanent</i> (<link to="IMachine::sharedFolders"/>),
11794	VM-specific shared folders available to the given virtual machine at
11795	startup.</li>
11796	<li><i>Transient</i> (<link to="IConsole::sharedFolders"/>),
11797	VM-specific shared folders created in the session context (for
11798	example, when the virtual machine is running) and automatically
11799	discarded when the session is closed (the VM is powered off).</li>
11800	</ul>
11801
11802	Logical names of shared folders must be unique within the given scope
11803	(global, permanent or transient). However, they do not need to be unique
11804	across scopes. In this case, the definition of the shared folder in a
11805	more specific scope takes precedence over definitions in all other
11806	scopes. The order of precedence is (more specific to more general):
11807	<ol>
11808	<li>Transient definitions</li>
11809	<li>Permanent definitions</li>
11810	<li>Global definitions</li>
11811	</ol>
11812
11813	For example, if MyMachine has a shared folder named
11814	<tt>C_DRIVE</tt> (that points to <tt>C:\\</tt>), then creating a
11815	transient shared folder named <tt>C_DRIVE</tt> (that points
11816	to <tt>C:\\\\WINDOWS</tt>) will change the definition
11817	of <tt>C_DRIVE</tt> in the guest OS so
11818	that <tt>\\\\VBOXSVR\\C_DRIVE</tt> will give access
11819	to <tt>C:\\WINDOWS</tt> instead of <tt>C:\\</tt> on the host
11820	PC. Removing the transient shared folder <tt>C_DRIVE</tt> will restore
11821	the previous (permanent) definition of <tt>C_DRIVE</tt> that points
11822	to <tt>C:\\</tt> if it still exists.

12234	<desc>
12235	The ISession interface represents a serialization primitive for virtual
12236	machines.
12237
12238	With VirtualBox, every time one wishes to manipulate a virtual machine
12239	(e.g. change its settings or start execution), a session object is
12240	required. Such an object must be passed to one of the session methods
12241	that open the given session, which then initiates the machine manipulation.
12242
12243	A session serves several purposes: it identifies to the inter-process VirtualBox
12244	code which process is currently working with the virtual machine, and it ensures
12245	that there are no incompatible requests from several processes for the
12246	same virtual machine. Session objects can therefore be thought of as mutex
12247	semaphores that lock virtual machines to prevent conflicting accesses from
12248	several processes.
12249
12250	How sessions objects are used depends on whether you use the Main API
12251	via COM or via the webservice:
12252
12253	<ul>
12254	<li>When using the COM API directly, an object of the Session class from the
12255	VirtualBox type library needs to be created. In regular COM C++ client code,
12256	this can be done by calling <tt>createLocalObject()</tt>, a standard COM API.
12257	This object will then act as a local session object in further calls to open
12258	a session.
12259	</li>
12260
12261	<li>In the webservice, the session manager (IWebsessionManager) instead creates
12262	one session object automatically when <link to="IWebsessionManager::logon" />
12263	is called. A managed object reference to that session object can be retrieved by
12264	calling <link to="IWebsessionManager::getSessionObject" />. This session object
12265	reference can then be used to open sessions.
12266	</li>
12267	</ul>
12268
12269	Sessions are mainly used in two variations:
12270
12271	<ul>
12272	<li>
12273	To start a virtual machine in a separate process, one would call
12274	<link to="IVirtualBox::openRemoteSession"/>, which requires a session
12275	object as its first parameter. This session then identifies the caller
12276	and lets him control the started machine (for example, pause machine
12277	execution or power it down) as well as be notified about machine
12278	execution state changes.
12279	</li>
12280
12281	<li>To alter machine settings, or to start machine execution within the
12282	current process, one needs to open a direct session for the machine first by
12283	calling <link to="IVirtualBox::openSession"/>. While a direct session
12284	is open within one process, no any other process may open another direct
12285	session for the same machine. This prevents the machine from being changed
12286	by other processes while it is running or while the machine is being configured.
12287	</li>
12288	</ul>
12289
12290	One also can attach to an existing direct session already opened by
12291	another process (for example, in order to send a control request to the
12292	virtual machine such as the pause or the reset request). This is done by
12293	calling <link to="IVirtualBox::openExistingSession"/>.
12294
12295	<note>
12296	Unless you are trying to write a new VirtualBox front-end that
12297	performs direct machine execution (like the VirtualBox or VBoxSDL
12298	front-ends), don't call <link to="IConsole::powerUp"/> in a direct
12299	session opened by <link to="IVirtualBox::openSession"/> and use this
12300	session only to change virtual machine settings. If you simply want to
12301	start virtual machine execution using one of the existing front-ends
12302	(for example the VirtualBox GUI or headless server), simply use
12303	<link to="IVirtualBox::openRemoteSession"/>; these front-ends
12304	will power up the machine automatically for you.

12335	manipulate a virtual machine, the caller invoke
12336	ISession::close() when it's done doing so. Since sessions are
12337	serialization primitives much like ordinary mutexes, they are
12338	best used the same way: for each "open" call, there should be
12339	a matching "close" call, even when errors occur.
12340
12341	Otherwise, if a direct session for a machine opened with
12342	<link to="IVirtualBox::openSession"/> is not explicitly closed
12343	when the application terminates, the state of the machine will
12344	be set to <link to="MachineState_Aborted" /> on the server.
12345
12346	Generally, it is recommended to close all open sessions explicitly
12347	before terminating the application (regardless of the reason for
12348	the termination).
12349
12350	<note>
12351	Do not expect the session state (<link to="ISession::state" />
12352	to return to "Closed" immediately after you invoke
12353	ISession::close(), particularly if you have started a remote
12354	session to execute the VM in a new process. The session state will
12355	automatically return to "Closed" once the VM is no longer executing,
12356	which can of course take a very long time.

12724	The IPerformanceCollector interface represents a service that collects and
12725	stores performance metrics data.
12726
12727	Performance metrics are associated with objects of interfaces like IHost and
12728	IMachine. Each object has a distinct set of performance metrics.
12729	The set can be obtained with <link to="IPerformanceCollector::getMetrics"/>.
12730
12731	Metric data is collected at the specified intervals and is retained
12732	internally. The interval and the number of retained samples can be set
12733	with <link to="IPerformanceCollector::setupMetrics" />.
12734
12735	Metrics are organized hierarchically, with each level separated by a
12736	slash (/) character. Generally, the scheme for metric names is like this:
12737
12738	<tt>Category/Metric[/SubMetric][:aggregation]</tt>
12739
12740	"Category/Metric" together form the base metric name. A base metric is the
12741	smallest unit for which a sampling interval and the number of retained
12742	samples can be set. Only base metrics can be enabled and disabled. All
12743	sub-metrics are collected when their base metric is collected.
12744	Collected values for any set of sub-metrics can be queried with
12745	<link to="IPerformanceCollector::queryMetricsData" />.
12746
12747	For example "CPU/Load/User:avg"
12748	metric name stands for the "CPU" category, "Load" metric, "User" submetric,
12749	"average" aggregate. An aggregate function is computed over all retained
12750	data. Valid aggregate functions are:
12751
12752	<ul>
12753	<li>avg -- average</li>
12754	<li>min -- minimum</li>
12755	<li>max -- maximum</li>
12756	</ul>
12757
12758	When setting up
12759	metric parameters, querying metric data, enabling or disabling metrics
12760	wildcards can be used in metric names to specify a subset of metrics. For
12761	example, to select all CPU-related metrics use <tt>CPU/*</tt>, all
12762	averages can be queried using <tt>*:avg</tt> and so on. To query metric
12763	values without aggregates <tt>*:</tt> can be used.
12764
12765	The valid names for base metrics are:
12766
12767	<ul>
12768	<li>CPU/Load</li>
12769	<li>CPU/MHz</li>
12770	<li>RAM/Usage</li>
12771	</ul>
12772
12773	The general sequence for collecting and retrieving the metrics is:
12774	<ul>
12775	<li>
12776	Obtain an instance of IPerformanceCollector with
12777	<link to="IVirtualBox::performanceCollector" />
12778	</li>
12779	<li>
12780	Allocate and populate an array with references to objects the metrics
12781	will be collected for. Use references to IHost and IMachine objects.
12782	</li>
12783	<li>
12784	Allocate and populate an array with base metric names the data will be
12785	collected for.
12786	</li>
12787	<li>
12788	Call <link to="IPerformanceCollector::setupMetrics" />. From now on the
12789	metric data will be collected and stored.
12790	</li>
12791	<li>
12792	Wait for the data to get collected.
12793	</li>
12794	<li>
12795	Allocate and populate an array with references to objects the metric
12796	values will be queried for. You can re-use the object array used for
12797	setting base metrics.
12798	</li>
12799	<li>
12800	Allocate and populate an array with metric names the data will be
12801	collected for. Note that metric names differ from base metric names.
12802	</li>
12803	<li>
12804	Call <link to="IPerformanceCollector::queryMetricsData" />. The data that
12805	have been collected so far are returned. Note that the values are still
12806	retained internally and data collection continues.

12988	Data collection continues behind the scenes after call to
12989	@c queryMetricsData. The return data can be seen as the snapshot of
12990	the current state at the time of @c queryMetricsData call. The
12991	internally kept metric values are not cleared by the call. This makes
12992	possible querying different subsets of metrics or aggregates with
12993	subsequent calls. If periodic querying is needed it is highly
12994	suggested to query the values with @c interval*count period to avoid
12995	confusion. This way a completely new set of data values will be
12996	provided by each query.
