Hmm, now that I've said this, I have a strong feeling that this is a lost
cause because other changes to QEMU master are going to break compatibility
with the libvirt stable branch soon enough (if not already).

Perhaps we should just update drvqemu.html to clearly indicate that if
you have QEMU >= 1.3.0 you need to have libvirt >= 1.0.0.
