34	/* Shared Folders Host Service.
35	*
36	* Shared Folders map a host file system to guest logical filesystem.
37	* A mapping represents 'host name'<->'guest name' translation and a root
38	* identifier to be used to access this mapping.
39	* Examples: "C:\WINNT"<->"F:", "C:\WINNT\System32"<->"/mnt/host/system32".
40	*
41	* Therefore, host name and guest name are strings interpreted
42	* only by host service and guest client respectively. Host name is
43	* passed to guest only for informational purpose. Guest may for example
44	* display the string or construct volume label out of the string.
45	*
46	* Root identifiers are unique for whole guest life,
47	* that is until next guest reset/fresh start.
48	* 32 bit value incremented for each new mapping is used.
49	*
50	* Mapping strings are taken from VM XML configuration on VM startup.
51	* The service DLL takes mappings during initialization. There is
52	* also API for changing mappings at runtime.
53	*
54	* Current mappings and root identifiers are saved when VM is saved.
55	*
56	* Guest may use any of these mappings. Full path information
57	* about an object on a mapping consists of the root identifier and
58	* a full path of object.
59	*
60	* Guest IFS connects to the service and calls SHFL_FN_QUERY_MAP
61	* function which returns current mappings. For guest convenience,
62	* removed mappings also returned with REMOVED flag and new mappings
63	* are marked with NEW flag.
64	*
65	* To access host file system guest just forwards file system calls
66	* to the service, and specifies full paths or handles for objects.
