How reproducible:
100%
Steps to Reproduce:
1. Create a volume from a qcow2 image.
2. Attach the volume to an instance and make changes.
3. Detach the volume from the instance.
4. Set the volume as read only.
5. Attach the volume to an instance.
Actual results:
the attachment fails.
Expected results:
the attachment should succeed, but the volume cannot be changed.
