Well, I'm tempted to say that's a problem for the virt guys :-)
One way one could solve that is by having the topology information
include the virt<->phys map, so that you can find the physical node from
the virtual cpu number.
Going to be interesting though, but then, virt seems to be about
creating problems where there were none before.
