+1 as well – this makes intuitive sense to me as a user, we should include
something in the mouseover text explaining that KVM acceleration will be
used if possible based on hardware capabilities

I suggest to call this item in the Wizard as "QEMU-KVM" with the following

"Select this option if you want to use QEMU as a hypervisor with capability

It looks like hypervisor much more than libvirt. Moreover, according
to Wikipedia [1] (don't blame me guys) Qemu is Type-2 hypervisor.

Sheena, are you sure it works this way? Some time ago we didn't
support this. However, I fully support this idea and believe this is
the way to go. In this case the hypervisor entry could be called
something like  "Qemu (+ KVM if available)".
