|

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).

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.
