Cleanup & destruction of domains is an area where there is relatively
high level of concurrency in libvirt. So it is conceivable that you
would see OPERATION_INVALID for a transient guest if libvirt is part
way through cleaning it up - it shouldn't be in that state for very
long though

You'll never see OPERATION_INVALID if the guest is truely running - it
will either be shutoff, or in the process of becoming shutoff very soon.
