I firmly believe that with qtest we'll end up eventually building a libOS to 
make it easier to write qtest tests.

Overtime, that libOS will become increasingly complex up until the point where 
it approaches something that feels like an actual OS.  Effort spent developing 
libOS is a cost to building test cases.

By using Linux and a minimal userspace as our libOS, we can avoid spending a lot 
of time building a sophisticated libOS.  If we need advanced libOS features, we 
just use qemu-test.  If it's just a matter of poking some registers on a device 
along, we just use qtest.

Guest neutral tests that are meant to run on Linux, Windows, etc. are in a 
completely different ballpark.
