1Preliminary notes:
2
31) The majority of code in the VirtualBox Open Source Edition (OSE) is
4copyrighted by Oracle Corporation. This code is combined with third-party code
5that was originally released under licenses which the Free Software Foundation
6considers incompatible with the GPL, such as the Apache License 2.0, the OpenSSL
7license, the Mozilla Public License (MPL) and the Slirp license. (Please see the
8VirtualBox User Manual for a complete list of third-party code and their
9licenses.) As a special exception to the terms and conditions of the GPL listed
10below, Oracle gives you explicit permission to combine its GPL code contained in
11VirtualBox OSE with third-party code under the aforementioned licenses. You may
12copy and distribute such a combination provided that you adhere to the terms and
13conditions of all of the GPL and the licenses of the third-party code; in
14particular, you must include the source code of the entire combination insofar
15as the GPL requires distribution of source code.
16
172) The GPL listed below does not bind software which uses VirtualBox services by
18merely linking to VirtualBox libraries so long as all VirtualBox interfaces used
19by that software are multi-licensed. A VirtualBox interface is deemed
20multi-licensed if it is declared in a VirtualBox header file that is licensed
21under both the GPL version 2 (below) *and* the Common Development and
22Distribution License Version 1.0 (CDDL), as it comes in the "COPYING.CDDL" file.
23In other words, calling such a multi-licensed interface is merely considered
24normal use of VirtualBox and does not turn the calling code into a derived work
25of VirtualBox. In particular, this applies to code that wants to extend
26VirtualBox by way of the Extension Pack mechanism declared in the ExtPack.h
27header file.
28
293) Whoever creates or distributes a derived work based on VirtualBox OSE is not
30obligated to grant the above exceptions for such a version. The GPL allows for
31releasing a modified version without the above exception; in addition, Oracle
32hereby also allows you to release a modified version which carries forward these
33exceptions.

40 GNU GENERAL PUBLIC LICENSE
41 Version 2, June 1991
42
43 Copyright (C) 1989, 1991 Free Software Foundation, Inc.
44 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
45 Everyone is permitted to copy and distribute verbatim copies
46 of this license document, but changing it is not allowed.
47
48 Preamble
49
50 The licenses for most software are designed to take away your
51freedom to share and change it. By contrast, the GNU General Public
52License is intended to guarantee your freedom to share and change free
53software--to make sure the software is free for all its users. This
54General Public License applies to most of the Free Software
55Foundation's software and to any other program whose authors commit to
56using it. (Some other Free Software Foundation software is covered by
57the GNU Library General Public License instead.) You can apply it to
58your programs, too.
59
60 When we speak of free software, we are referring to freedom, not
61price. Our General Public Licenses are designed to make sure that you
62have the freedom to distribute copies of free software (and charge for
63this service if you wish), that you receive source code or can get it
64if you want it, that you can change the software or use pieces of it
65in new free programs; and that you know you can do these things.
66
67 To protect your rights, we need to make restrictions that forbid
68anyone to deny you these rights or to ask you to surrender the rights.
69These restrictions translate to certain responsibilities for you if you
70distribute copies of the software, or if you modify it.
71
72 For example, if you distribute copies of such a program, whether
73gratis or for a fee, you must give the recipients all the rights that
74you have. You must make sure that they, too, receive or can get the
75source code. And you must show them these terms so they know their
76rights.
77
78 We protect your rights with two steps: (1) copyright the software, and
79(2) offer you this license which gives you legal permission to copy,
80distribute and/or modify the software.
81
82 Also, for each author's protection and ours, we want to make certain
83that everyone understands that there is no warranty for this free
84software. If the software is modified by someone else and passed on, we
85want its recipients to know that what they have is not the original, so
86that any problems introduced by others will not reflect on the original
87authors' reputations.
88
89 Finally, any free program is threatened constantly by software
90patents. We wish to avoid the danger that redistributors of a free
91program will individually obtain patent licenses, in effect making the
92program proprietary. To prevent this, we have made it clear that any
93patent must be licensed for everyone's free use or not licensed at all.
94
95 The precise terms and conditions for copying, distribution and
96modification follow.
97
98 GNU GENERAL PUBLIC LICENSE
99 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
100
101 0. This License applies to any program or other work which contains
102a notice placed by the copyright holder saying it may be distributed
103under the terms of this General Public License. The "Program", below,
104refers to any such program or work, and a "work based on the Program"
105means either the Program or any derivative work under copyright law:
106that is to say, a work containing the Program or a portion of it,
107either verbatim or with modifications and/or translated into another
108language. (Hereinafter, translation is included without limitation in
109the term "modification".) Each licensee is addressed as "you".
110
111Activities other than copying, distribution and modification are not
112covered by this License; they are outside its scope. The act of
113running the Program is not restricted, and the output from the Program
114is covered only if its contents constitute a work based on the
115Program (independent of having been made by running the Program).
116Whether that is true depends on what the Program does.
117
118 1. You may copy and distribute verbatim copies of the Program's
119source code as you receive it, in any medium, provided that you
120conspicuously and appropriately publish on each copy an appropriate
121copyright notice and disclaimer of warranty; keep intact all the
122notices that refer to this License and to the absence of any warranty;
123and give any other recipients of the Program a copy of this License
124along with the Program.
125
126You may charge a fee for the physical act of transferring a copy, and
127you may at your option offer warranty protection in exchange for a fee.
128
129 2. You may modify your copy or copies of the Program or any portion
130of it, thus forming a work based on the Program, and copy and
131distribute such modifications or work under the terms of Section 1
132above, provided that you also meet all of these conditions:
133
134 a) You must cause the modified files to carry prominent notices
135 stating that you changed the files and the date of any change.
136
137 b) You must cause any work that you distribute or publish, that in
138 whole or in part contains or is derived from the Program or any
139 part thereof, to be licensed as a whole at no charge to all third
140 parties under the terms of this License.
141
142 c) If the modified program normally reads commands interactively
143 when run, you must cause it, when started running for such
144 interactive use in the most ordinary way, to print or display an
145 announcement including an appropriate copyright notice and a
146 notice that there is no warranty (or else, saying that you provide
147 a warranty) and that users may redistribute the program under
148 these conditions, and telling the user how to view a copy of this
149 License. (Exception: if the Program itself is interactive but
150 does not normally print such an announcement, your work based on
151 the Program is not required to print an announcement.)
152
153These requirements apply to the modified work as a whole. If
154identifiable sections of that work are not derived from the Program,
155and can be reasonably considered independent and separate works in
156themselves, then this License, and its terms, do not apply to those
157sections when you distribute them as separate works. But when you
158distribute the same sections as part of a whole which is a work based
159on the Program, the distribution of the whole must be on the terms of
160this License, whose permissions for other licensees extend to the
161entire whole, and thus to each and every part regardless of who wrote it.
162
163Thus, it is not the intent of this section to claim rights or contest
164your rights to work written entirely by you; rather, the intent is to
165exercise the right to control the distribution of derivative or
166collective works based on the Program.
167
168In addition, mere aggregation of another work not based on the Program
169with the Program (or with a work based on the Program) on a volume of
170a storage or distribution medium does not bring the other work under
171the scope of this License.
172
173 3. You may copy and distribute the Program (or a work based on it,
174under Section 2) in object code or executable form under the terms of
175Sections 1 and 2 above provided that you also do one of the following:
176
177 a) Accompany it with the complete corresponding machine-readable
178 source code, which must be distributed under the terms of Sections
179 1 and 2 above on a medium customarily used for software interchange; or,
180
181 b) Accompany it with a written offer, valid for at least three
182 years, to give any third party, for a charge no more than your
183 cost of physically performing source distribution, a complete
184 machine-readable copy of the corresponding source code, to be
185 distributed under the terms of Sections 1 and 2 above on a medium
186 customarily used for software interchange; or,
187
188 c) Accompany it with the information you received as to the offer
189 to distribute corresponding source code. (This alternative is
190 allowed only for noncommercial distribution and only if you
191 received the program in object code or executable form with such
192 an offer, in accord with Subsection b above.)
193
194The source code for a work means the preferred form of the work for
195making modifications to it. For an executable work, complete source
196code means all the source code for all modules it contains, plus any
197associated interface definition files, plus the scripts used to
198control compilation and installation of the executable. However, as a
199special exception, the source code distributed need not include
200anything that is normally distributed (in either source or binary
201form) with the major components (compiler, kernel, and so on) of the
202operating system on which the executable runs, unless that component
203itself accompanies the executable.
204
205If distribution of executable or object code is made by offering
206access to copy from a designated place, then offering equivalent
207access to copy the source code from the same place counts as
208distribution of the source code, even though third parties are not
209compelled to copy the source along with the object code.
210
211 4. You may not copy, modify, sublicense, or distribute the Program
212except as expressly provided under this License. Any attempt
213otherwise to copy, modify, sublicense or distribute the Program is
214void, and will automatically terminate your rights under this License.
215However, parties who have received copies, or rights, from you under
216this License will not have their licenses terminated so long as such
217parties remain in full compliance.
218
219 5. You are not required to accept this License, since you have not
220signed it. However, nothing else grants you permission to modify or
221distribute the Program or its derivative works. These actions are
222prohibited by law if you do not accept this License. Therefore, by
223modifying or distributing the Program (or any work based on the
224Program), you indicate your acceptance of this License to do so, and
225all its terms and conditions for copying, distributing or modifying
226the Program or works based on it.
227
228 6. Each time you redistribute the Program (or any work based on the
229Program), the recipient automatically receives a license from the
230original licensor to copy, distribute or modify the Program subject to
231these terms and conditions. You may not impose any further
232restrictions on the recipients' exercise of the rights granted herein.
233You are not responsible for enforcing compliance by third parties to
234this License.
235
236 7. If, as a consequence of a court judgment or allegation of patent
237infringement or for any other reason (not limited to patent issues),
238conditions are imposed on you (whether by court order, agreement or
239otherwise) that contradict the conditions of this License, they do not
240excuse you from the conditions of this License. If you cannot
241distribute so as to satisfy simultaneously your obligations under this
242License and any other pertinent obligations, then as a consequence you
243may not distribute the Program at all. For example, if a patent
244license would not permit royalty-free redistribution of the Program by
245all those who receive copies directly or indirectly through you, then
246the only way you could satisfy both it and this License would be to
247refrain entirely from distribution of the Program.
248
249If any portion of this section is held invalid or unenforceable under
250any particular circumstance, the balance of the section is intended to
251apply and the section as a whole is intended to apply in other
252circumstances.
253
254It is not the purpose of this section to induce you to infringe any
255patents or other property right claims or to contest validity of any
256such claims; this section has the sole purpose of protecting the
257integrity of the free software distribution system, which is
258implemented by public license practices. Many people have made
259generous contributions to the wide range of software distributed
260through that system in reliance on consistent application of that
261system; it is up to the author/donor to decide if he or she is willing
262to distribute software through any other system and a licensee cannot
263impose that choice.
264
265This section is intended to make thoroughly clear what is believed to
266be a consequence of the rest of this License.
267
268 8. If the distribution and/or use of the Program is restricted in
269certain countries either by patents or by copyrighted interfaces, the
270original copyright holder who places the Program under this License
271may add an explicit geographical distribution limitation excluding
272those countries, so that distribution is permitted only in or among
273countries not thus excluded. In such case, this License incorporates
274the limitation as if written in the body of this License.
275
276 9. The Free Software Foundation may publish revised and/or new versions
277of the General Public License from time to time. Such new versions will
278be similar in spirit to the present version, but may differ in detail to
279address new problems or concerns.
280
281Each version is given a distinguishing version number. If the Program
282specifies a version number of this License which applies to it and "any
283later version", you have the option of following the terms and conditions
284either of that version or of any later version published by the Free
285Software Foundation. If the Program does not specify a version number of
286this License, you may choose any version ever published by the Free Software
287Foundation.
288
289 10. If you wish to incorporate parts of the Program into other free
290programs whose distribution conditions are different, write to the author
291to ask for permission. For software which is copyrighted by the Free
292Software Foundation, write to the Free Software Foundation; we sometimes
293make exceptions for this. Our decision will be guided by the two goals
294of preserving the free status of all derivatives of our free software and
295of promoting the sharing and reuse of software generally.
296
297 NO WARRANTY
298
299 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
300FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
301OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
302PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
303OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
304MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
305TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
306PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
307REPAIR OR CORRECTION.
308
309 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
310WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
311REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
312INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
313OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
314TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
315YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
316PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
317POSSIBILITY OF SUCH DAMAGES.
318
319 END OF TERMS AND CONDITIONS
320
321 How to Apply These Terms to Your New Programs
322
323 If you develop a new program, and you want it to be of the greatest
324possible use to the public, the best way to achieve this is to make it
325free software which everyone can redistribute and change under these terms.
326
327 To do so, attach the following notices to the program. It is safest
328to attach them to the start of each source file to most effectively
329convey the exclusion of warranty; and each file should have at least
330the "copyright" line and a pointer to where the full notice is found.
331
332 <one line to give the program's name and a brief idea of what it does.>
333 Copyright (C) <year> <name of author>
334
335 This program is free software; you can redistribute it and/or modify
336 it under the terms of the GNU General Public License as published by
337 the Free Software Foundation; either version 2 of the License, or
338 (at your option) any later version.
339
340 This program is distributed in the hope that it will be useful,
341 but WITHOUT ANY WARRANTY; without even the implied warranty of
342 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
343 GNU General Public License for more details.
344
345 You should have received a copy of the GNU General Public License
346 along with this program; if not, write to the Free Software
347 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
348
349
350Also add information on how to contact you by electronic and paper mail.
351
352If the program is interactive, make it output a short notice like this
353when it starts in an interactive mode:
354
355 Gnomovision version 69, Copyright (C) year name of author
356 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
357 This is free software, and you are welcome to redistribute it
358 under certain conditions; type `show c' for details.
359
360The hypothetical commands `show w' and `show c' should show the appropriate
361parts of the General Public License. Of course, the commands you use may
362be called something other than `show w' and `show c'; they could even be
363mouse-clicks or menu items--whatever suits your program.
364
365You should also get your employer (if you work as a programmer) or your
366school, if any, to sign a "copyright disclaimer" for the program, if
367necessary. Here is a sample; alter the names:
368
369 Yoyodyne, Inc., hereby disclaims all copyright interest in the program
370 `Gnomovision' (which makes passes at compilers) written by James Hacker.
371
372 <signature of Ty Coon>, 1 April 1989
373 Ty Coon, President of Vice
374
375This General Public License does not permit incorporating your program into
376proprietary programs. If your program is a subroutine library, you may
377consider it more useful to permit linking proprietary applications with the
378library. If this is what you want to do, use the GNU Lesser General
379Public License instead of this License.
