the point is
a) we didn't upgrade, but started from scratch with ceph 12
b) we didn't test all of the new features in ceph 12 (eg. EC pools for RBD devices) in connection with cinder yet

We are half year on Ceph with oVirt in production. The best storage experience, the only thing you can find fault this is impossible to move images between pools. Only manually migration with qemu-img/rados or cp/rsync inside VM.
