Title:
  error injecting data into image when launching from volume

Status in OpenStack Compute (Nova):
  Triaged

Bug description:
  branch: master
  commit: ae251b99a3fb6aa99ec8898152d79dfa2c026a92

  I launch the instance from a sheepdog volume without specifying an
  image when launching.

  The following error occurred:

  Clearly, nova tries to inject to an image file that doesn't exist on
  disk. We may need to skip injecting the data when launching from a
  volume.
