Title:
  Snapshot not created with any container_format column

Status in OpenStack Image Registry and Delivery Service (Glance):
  Invalid
Status in OpenStack Dashboard (Horizon):
  Won't Fix
Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  ======UPDATE=============

  Got some more information on that problem:
  What happened was something like this, not entirely sure about all sequences:
  - create VM1 from image, do something with VM1, create snapshot of VM1
  - create VM2 from snapshot, stop VM1, do something with VM2, create snapshot of VM2
  - create VM3 from snapshot, stop VM2, delete snapshot of VM2

  So the situation was this: There's a VM created from a snapshot and
  the snapshot image was deleted. Creating a snapshot in that situation
  was impossible and resulted in the stacktrace

  
  =======ORIGINAL=============

  
  I've got an Openstack setup with one controller node (glance, keystone, horizon, nova-* (except nova-compute)) and three compute nodes. I wanted to create a snapshot of a vm running on one of the compute nodes, by using the option in the horizon dashboard.

  What happens is that the snapshot gets listed as a snapshot, but with
  the status queued. And from there on nothing happens anymore.

  In the nova-compute.log on the compute host I can see these entries:

  I checked with the api.log of glance and found these entries:

  Any idea what's going wrong here?
