Isn't the policy decision in question here to only have one kernel
source in a release?

Unusable for production work. Emulation is just too slow. The group of
people that can live with that much slow down compared to xen is
miniscule.

KVM needs hardware support and even then its I/O is slower. It also
deadlocks the I/O under I/O load from time to time.
I could live with the I/O slowdown but nothing will make hardware
magically appear.
