we want to use a Ceph cluster as the main storage for our oVirt 4.1.x datacenter. We successfully tested using librbd1-12.2.1-0.el7 package from Ceph repos instead of the standard librbd1-0.94.5-2.el7 from CentOS 7 in an oVirt virtualization node. Are there any caveats when doing so? Will this work in oVirt 4.2?
Hello Matthias. Can I ask separate question? At this time we atoVirt 4.1.3.5 and Ceph Cluster at 11.2.0 (Kraken).In few weeks I planned to expand the cluster and I would like to upgrade to Ceph 12 (Luminous), for bluestore support. So my question is:have you tested oVirt with Ceph 12?
Thanks.

Since /usr/lib64/libvirt/storage-backend/libvirt_storage_backend_rbd.so is using /lib64/librbd.so.1 our VMs with disks from Cinder storage domain are using Ceph 12 all the way. Are you also using a newer librbd1? Regards Matthias
