Comment 5 for bug 1447215

This issue may be linked to this https://bugs.launchpad.net/nova/+bug/1467570 . Basically, I have just been confirmed that Nova provisions instances from rbd by querying glanceV2. While it affects the code for ephemeral rbd snapshots, as said earlier, this also affect the code for provisioning instances in Kilo and prevents VMs from booting from snapshot when using a rbd backend.

Hence, a backport of this bug fix for kilo would be strongly appreciated.
