This is borderline between new feature (since it is new XML) and bug
fix, but I'm leaning towards bug-fix, since otherwise our use of numad
is not very efficient given the default XML that people used to just
place <vcpu>.  Therefore, I've gone ahead and pushed the first four
patches in time for 0.9.12.
