Title:
Fail to fetch non-raw image on image_backend=RBD
Status in OpenStack Compute (Nova):
Confirmed
Bug description:
Using the image_backend RBD and booting a non-raw image results in a fallback
to fetch_to_raw function where the goal is to download the qcow2 image on the
compute, convert it into raw and import it into ceph.
