What I mean is: if asked to enable kvm but kvm

What I've been thinking, is that we should make kvm enablement a -cpu
option. Something like:
-cpu host,accel=kvm
-cpu host,accel=tcg
-cpu host,accel=kvm:tcg
(1) would be KVM only, (2) would be TCG only, (3) would be KVM falling
back to TCG.
What's nice about this approach, is that we already pull CPU model
definitions from a global config file which means that you could tweak
this parameter to your liking.
