If yes, Well a "lease" is not a device per-se. It's just libvirt putting it with devices. Currently the "lease" is always successfully removed/unplugged if the API returns success as there is no cooperation with qemu necessary so the semantics of asking the guest OS to do something don't apply. > is there any better way of checking that <lease> removal is completed > than querying and examining the domain XML?

Yes, we probably should add the event and synthetize it for "lease" since we will not get one from qemu. Also we'll need to add alias for the lease so that the event can be used.
