Comment 1 for bug 1815949

Marking this as Confirmed based on the traceback -- we can see that libvirt is raising an 'internal error' for a 'not found' condition, which our current code does not expect. To be thorough, we should locate where in the libvirt source this is raised, to see if we can learn the origin of this new error combo (if it's a change from a newer version of libvirt, etc).
