8.04 is not a good test-case.  7.10 is what you want to try.

The good news is, 7.10 appears to work!  The bad news is that about 20% 
of the time, it crashes and displays the following:

kvm_run: failed entry, reason 5
kvm_run returned -8

So something appears to be a bit buggy.  Still, very good work!
