After that, I think the best thing to do is to move from emulating a

the theory that it probably knows how to better then we do.  However,
this is a much larger undertaking, as it requires learning the driver
model of the guest OSes.

I agree that emulating a "custom" driver model should give better performance 
than emulating real hardware (VMware does this). However I think you should 
provide all the functionality you possibly can, even if the host doesn't 
provide native acceleration for it. It's always going to be faster to do 
something in software on the host than it is on the guest.
