We do have an RFE to choose the CPU model in libvirt, but that wouldn't
let us specify topology, since QEMU doesn't allow that to be expressed
via its -cpu arg at this time.

I've just been pointed to this proposed enhancement to QEMU for 
choosing topology:

  http://patchwork.kernel.org/patch/33961/

That discussion is still ongoing, but once its settled we'll be able to 
look at supporting it in libvirt too.
