<p class="MsoNormal">Openstack is usually pretty good about failing and reverting when one step of the operation chain failed. That said, this is anecdotal but the most amount of mismatch between the VM and the DB is always around Cinder. Which kind of makes
sense since it's probably volume attach + detach that are the most common. Maybe port operations after.<o:p></o:p></p>
