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.
Tried that with no luck so far.
virsh # setvcpus gentookvm --guest 2
error: internal error: unable to execute QEMU agent command
'guest-get-vcpus': The command guest-get-vcpus has not been found
It's qemu-1.4.2 and libvirt-1.1.1.
In general it seems to work.
virsh # shutdown 3 --mode agent
Domain 3 is being shutdown
Any hints? And once again, thanks for your support Eric.
cheers
