19	*
20	* The VM Information subservice provides heaps of useful information about the
21	* VM via guest properties.
22	*
23	* Guest properties is a limited database maintained by the HGCM GuestProperties
24	* service in cooperation with the Main API (VBoxSVC). Properties have a name
25	* (ours are path like), a string value, and a nanosecond timestamp (unix
26	* epoch). The timestamp lets the user see how recent the information is. As
27	* an laternative to polling on changes, it is also possible to wait on changes
28	* via the Main API or VBoxManage on the host side and VBoxControl in the guest.
29	*
30	* The namespace "/VirtualBox/" is reserved for value provided by VirtualBox.
31	* This service provides all the information under "/VirtualBox/GuestInfo/".
32	*
33	*
34	* @section sec_vgsvc_vminfo_beacons Beacons
35	*
36	* The subservice does not write properties unless there are changes. So, in
37	* order for the host side to know that information is up to date despite an
38	* oldish timestamp we define a couple of values that are always updated and can
39	* reliably used to figure how old the information actually is.
40	*
41	* For the networking part "/VirtualBox/GuestInfo/Net/Count" is the value to
42	* watch out for.
43	*
44	* For the login part, it's possible that we intended to use
45	* "/VirtualBox/GuestInfo/OS/LoggedInUsers" for this, however it is not defined
46	* correctly and current does NOT work as a beacon.
47	*
