22/** @page pg_vm VM API
23 *
24 * This is the encapsulating bit. It provides the APIs that Main and VBoxBFE
25 * use to create a VMM instance for running a guest in. It also provides
26 * facilities for queuing request for execution in EMT (serialization purposes
27 * mostly) and for reporting error back to the VMM user (Main/VBoxBFE).
28 *
29 *
30 * @section sec_vm_design Design Critique / Things To Do
31 *
32 * In hindsight this component is a big design mistake, all this stuff really
33 * belongs in the VMM component. It just seemed like a kind of ok idea at a
34 * time when the VMM bit was a bit vague. 'VM' also happend to be the name of
35 * the per-VM instance structure (see vm.h), so it kind of made sense. However
36 * as it turned out, VMM(.cpp) is almost empty all it provides in ring-3 is some
37 * minor functionally and some "routing" services.
38 *
39 * Fixing this is just a matter of some more or less straight forward
40 * refactoring, the question is just when someone will get to it.
