This teaches libvirt's RBD image backend about the outside world, that other ceph clusters may exist, and how to use Glance's multi-store image import-via-copy mechanism. The basic theory is that when we go to do the normal CoW clone for RBD, we do the "does this image have a location that matches my RBD backend?" check. If that check does not pass, if configured, we avoid failing and ask Glance to copy it to our store instead. After that has completed, we just recurse (once) and re-try our existing logic to see if the image is now in a reachable location. If so, we pass like we would have originally, and if not, we fail in the same way we would have. The copy-to-store logic sets up a looping poll to check for copy completion every N seconds according to a tunable, with a total timeout value in case it never completes. If the timeout expires or Glance reports failure, we will treat that the same as unreachable-due-to-location.

In the unfortunate event that bugs are discovered, they should be reported to the appropriate bug tracker. If you obtained the software from a 3rd party operating system vendor, it is often wise to use their own bug tracker for reporting problems. In all other cases use the master OpenStack bug tracker, available at:
