It works for xen:// URIs. Upstream qemu vcpu hotplug is still a work in
progress; I don't know if qemu 1.6 will support it, or if you'll have to
wait for qemu 1.7. Meanwhile, you can try using 'setvcpus gentookvm
--guest 4' to use the guest agent (assuming you have qemu-ga running in
the guest, and the proper plumbing of the guest agent channel in your
domain XML) to use the guest to take vcpus on- or offline.
