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. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
