Thanks a lot for your advice...
I'm specially interested in feature "Exclusive locking". Enabling this
feature can affect live/offline migration? In this scenario (online/offline
migration) I don't know if two hosts (source and destination) need access
to the same rbd image at the same time
It looks that enabling Exlucisve locking you can enable some other
interessant features like "Object map" and/or "Fast diff" for backups.
Thanks a lot!
