Ahh, but the question is worded such that the virtualization is running
on windows. Therefore you have a lot of display overhead due to a
windows environment. You also are just an application running in an OS,
so you have to convince the OS to give you appropriate resources. So
while the application isn't necessarily too inefficient, you are already
running in an OS that can starve your emulator, and then you have
another OS that can starve asterisk from running at the required speed.

Again, it is possible, just not recommended no matter what the
underlying hardware is. Give asterisk at least a chance of working
properly on its own before you handicap it. As the learning curve is
enough already, don't augment it by adding artificial barriers.
