I might consider having 'xm create' or the domain-config-cooking bit of xend
grind a new cores_per_socket config option into the canonical cpuid option.
I don't think it should be part of the persistent vm configuration state
that xend keeps in xenstore and saves/restores. And this could be done
equally well in higher-level tools.
