Moving this to Cinder for evaluation. Glance just stores the bits, I
don't expect that having anything to do about Cinder not able to create
volume from them specially if different format works.

** Project changed: glance => cinder

Title:
  Cinder cannot create volume from RAW glance image

Status in Cinder:
  New

Bug description:
  Make a RAW image from some files:

  virt-make-fs --type=ext4 --format=raw --size=+500M /tmp/tmpb3abEh /tmp/binary-9bHVxp.raw
  glance -v -d  image-create --name my-binary-img-test --disk-format raw --container-format bare --file /tmp/binary-9bHVxp.raw
  cinder  create --display-name my-test4 --image-id <glance-uuid> 7

  This used to work fine on Kilo: 2015.1.0. On Kilo 2015.1.1 the volume
  gets stuck in "Downloading"

  cinder list --all-tenants

  This is affecting several of our testbeds. A workaround is to use a QCOW2 image instead of RAW. This is not a solution as some setups have CEPH backed storage which don't play well with QCOW2 formats.
