| We don't support yet copying disks to ceph, only creating new disks.

| This should work:

| 1. Create vm with ceph disk

| 2. Find the ceph disk name in cinder using the disk name in engine

| 3. Copy the image manually to ceph using ceph command line tools
| The machine copying the disks should have cephx auth keys
| deployed.

| Note that ovirt hosts do not deploy ceph auth keys on the host, we
| deploy the keys dynamically using libvirt secrets, so only vms that
| need access to ceph disk can access it.

| Adding Daniel to add more details on how to find the cinder disk.

| There are some ceph users on this list, maybe they can add more
| details.
