Title:
Boot from ceph volume fails
Status in OpenStack Compute (Nova):
Invalid
Bug description:
I have setup OpenStack to work with ceph. As far as I can see,
everything is setup correctly. I can attach an ceph block device to a
running instance.
But I'm unable to boot a instance from a ceph volume.
The error is the same like in #1126348.
