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).
On oVirt Hypervisor hosts we use librbd1-0.94.5-1.el7.x86_64
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.
Our OpenStack cinder is openstack-cinder-10.0.0-1.el7.noarch with
librbd1-10.2.3-0.el7.x86_64
we're also using cinder from openstack ocata release.
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
