	19	*
	20	* This is the encapsulating bit. It provides the APIs that Main and VBoxBFE
	21	* use to create a VMM instance for running a guest in. It also provides
	22	* facilities for queuing request for execution in EMT (serialization purposes
	23	* mostly) and for reporting error back to the VMM user (Main/VBoxBFE).
	24	*
	25	*
	26	* @section sec_vm_design Design Critique / Things To Do
	27	*
	28	* In hindsight this component is a big design mistake, all this stuff really
	29	* belongs in the VMM component. It just seemed like a kind of ok idea at a
[33540]	30	* time when the VMM bit was a kind of vague. 'VM' also happened to be the name
[22986]	31	* of the per-VM instance structure (see vm.h), so it kind of made sense.
	32	* However as it turned out, VMM(.cpp) is almost empty all it provides in ring-3
	33	* is some minor functionally and some "routing" services.
[13667]	34	*
	35	* Fixing this is just a matter of some more or less straight forward
[22986]	36	* refactoring, the question is just when someone will get to it. Moving the EMT
	37	* would be a good start.
