It's interesting, since we use transient domains. Are there > known circumstances when OPERATION_INVALID could be returned for a > transient domain? Can we assume that we never receive that error when > trying to destroy a running domain? 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.
