I suspect this information is not available from the Xen hypervisor. If it is, then we ought to expose it where possible. Yes you can tell this by using the terribly complicated 'virDomainGetVcpus' function. Read the manual page _very_ carefully for this one :-( virt-top uses this function to display the % used and mapping of VCPUs to PCPUs in real time, so you might find playing with virt-top and looking at the code useful: http://hg.et.redhat.com/virt/applications/virt-top--devel?f=e100f86fdf28;... This is sort of possible.

Imagine rephrasing the question as "Can I get the IP address of each machine on my LAN?".
