I think the problem is poor modeling.  We specify "virt_type", but export the 

The "virt_type" option does not have a 1:1 mapping to hypervisor.  Both kvm and 
qemu will use the "qemu" hypervisor but kvm will enable hardware acceleration.

Perhaps we should change it to export "virt_type" instead via a microversion.
