I've tried it both with jewel (official containers) and kraken (custom containers), and it works pretty well.</div><div class="gmail_msg">The real problem is not creating and configuring a ceph cluster, but using it from ovirt, as it requires cinder, i.e. a minimal setup of openstack. We have it and it's working pretty well, but it requires some work.
