[libvirt] [PATCH 0/6] Fix state driver hotplug semantics

Currently, domain hotplug operations in the state drivers (QEMU, LXC, ...)
have strange semantics: a hotplug config change will stick around in memory
until the domain is either redefined or libvirtd is restarted.

This series fixes hotplug config changes to be discarded when the VM is
stopped, which AFAICT is the expected behavior. A few bugs with setvcpus
implementations are also addressed.

Thanks,
Cole
