Hi Konstantin,

yes, we have a Ceph 12 Cluster and are using librbd1-12.2.1 on oVirt 
Hypervisor Hosts, which we're installed with CentOS 7 and Ceph upstream 
repos, not oVirt Node (for this exact purpose). 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
