kvm uses a different memory layout (slots in qemu/kvm lingo), that means
that memory can't be migrated (that is a big problem).  Once that is
"fixed", you need to work on the several in-kernel chips that don't
exist in qemu (kvm-irq-chip and the like).  Once that is fixed, you can
look for what more things are broken.

Once here, why do you want to do that switch?

Later, Juan.
