Hi, your question is a bit "thin", I'd say. A lot has changed in Tentacle [0], but nothing of the mentioned changes looks critical wrt libvirt from my perspective. Do you have any logs or more detailed descriptions what exactly fails? We haven't upgraded to v20 yet, at least not our prod cluster, we also use RBD heavily (OpenStack on Ubuntu), so this is quite relevant for us.
