Right, to a large extent. However, our QEMU package is much closer to
qemu-kvm-rhev than to CentOS' qemu-kvm. It's still different from
qemu-kvm-rhev in some respects so we don't feel comfortable providing
"qemu-kvm-rhev" in our package.

This is clear :) I'm interested in a longer reply to "why", in order to
figure out how to correctly run Nova on top of Virtuozzo.
