37	/* Shared Folders Host Service.
38	*
39	* Shared Folders map a host file system to guest logical filesystem.
40	* A mapping represents 'host name'<->'guest name' translation and a root
41	* identifier to be used to access this mapping.
42	* Examples: "C:\WINNT"<->"F:", "C:\WINNT\System32"<->"/mnt/host/system32".
43	*
44	* Therefore, host name and guest name are strings interpreted
45	* only by host service and guest client respectively. Host name is
46	* passed to guest only for informational purpose. Guest may for example
47	* display the string or construct volume label out of the string.
48	*
49	* Root identifiers are unique for whole guest life,
50	* that is until next guest reset/fresh start.
51	* 32 bit value incremented for each new mapping is used.
52	*
53	* Mapping strings are taken from VM XML configuration on VM startup.
54	* The service DLL takes mappings during initialization. There is
55	* also API for changing mappings at runtime.
56	*
57	* Current mappings and root identifiers are saved when VM is saved.
58	*
59	* Guest may use any of these mappings. Full path information
60	* about an object on a mapping consists of the root indentifier and
61	* a full path of object.
62	*
63	* Guest IFS connects to the service and calls SHFL_FN_QUERY_MAP
64	* function which returns current mappings. For guest convenience,
65	* removed mappings also returned with REMOVED flag and new mappings
66	* are marked with NEW flag.
67	*
68	* To access host file system guest just forwards file system calls
69	* to the service, and specifies full paths or handles for objects.
