You *could*, sure. I have done this for local builds here. But if you
go that route I would recommend making a patch to KVM so it doesn't fall
back into QEMU mode automatically (today if it can't open the kvm module
it will assume "-no-kvm" like behavior). Otherwise you will have a
bunch of support calls about why its not working properly should someone
cause the system to fall back.

Ill defer to Avi here, though as I understand it: Things that benefit
the upstream source get pushed...things that are KVM only don't.
