Public bug reported:

Trace ends with:

TRACE nova.compute.manager [instance: c1edd5bf-ba48-4374-880f-1f5fa2f41cd3]  File "/opt/stack/nova/nova/virt/libvirt/rbd.py", line 238, in exists
TRACE nova.compute.manager [instance: c1edd5bf-ba48-4374-880f-1f5fa2f41cd3]     except rbd.ImageNotFound:
TRACE nova.compute.manager [instance: c1edd5bf-ba48-4374-880f-1f5fa2f41cd3] AttributeError: 'module' object has no attribute 'ImageNotFound'

It looks like the above module tries to do a "import rbd" and ends up
importing itself again instead of the global library module.

A quick fix would be renaming the file to rbd2.py and changing the
references in driver.py and imagebackend.py, but maybe there is a better
solution?
