19	*
20	* The configuration manager is a directory containing the VM configuration at
21	* run time. It works in a manner similar to the windows registry - it's like a
22	* file system hierarchy, but the files (values) live in a separate name space
23	* and can include the path separators.
24	*
25	* The configuration is normally created via a callback passed to VMR3Create()
26	* via the pfnCFGMConstructor parameter. To make testcase writing a bit simpler,
27	* we allow the callback to be NULL, in which case a simple default
28	* configuration will be created by CFGMR3ConstructDefaultTree(). The
29	* Console::configConstructor() method in Main/ConsoleImpl2.cpp creates the
30	* configuration from the XML.
31	*
32	* Devices, drivers, services and other PDM stuff are given their own subtree
33	* where they are protected from accessing information of any parents. This is
34	* is implemented via the CFGMR3SetRestrictedRoot() API.
35	*
36	* Data validation out over the basic primitives is left to the caller. The
37	* caller is in a better position to know the proper validation rules of the
38	* individual properties.
39	*
40	* @see grp_cfgm
41	*
42	*
43	* @section sec_cfgm_primitives Data Primitives
44	*
45	* CFGM supports the following data primitives:
46	* - Integers. Representation is unsigned 64-bit. Boolean, unsigned and
47	* small integers, and pointers are all represented using this primitive.
48	* - Zero terminated character strings. These are of course UTF-8.
49	* - Variable length byte strings. This can be used to get/put binary
50	* objects like for instance RTMAC.
