[ovirt-users] Cloning a VM with Ceph/Cinder based disk leaves disk in locked state

Dear oVirt Users,

we're using cinder (based on the Kolla setup) to provide storage for
ovirt. Everything works fine except the clone process of a VM.
Cloning a VM with NFS based storage works as expected, thus I think it's
the cinder integration that causes the problem here.

When cloning a VM with cinder/ceph-based storage we see, that the VM
clone is created, the attached image is cloned as well, but the
disk/image remains in locked state. We then need to issue a

"update images set imagestatus=1 where imagestatus=2;"

on the engine to make the VM clone work.

Is this a bug in the cinder integration?

Thanks and best regards,
 Thomas
