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 What version of Cinder I should have for work with Ceph 12? Or just upgrade python-rbd/librados/librbd1/etc.
I'll talk to my colleague, who is the Ceph expert, about this tomorrow. Regards Matthias
