Hi Joe,

Looking at the same part of the XML description as you did:

 http://libvirt.org/formatdomain.html#elementsCPU

You're right, in that it shows we have some kind of capacity to process that info.

Some questions that might help us find the answer:

 + What's the virtualisation host you're trying this out on?

    i.e. KVM/Xen/vSphere/ESX/VirtualBox/etc

 + Which version of libvirt is it running?

 + What guest OS's have you tried with?

Regards and best wishes,

Justin Clift
