billy-olsen: from the launchpad bug status description: "invalid" means:
"the report describes the software's normal behaviour, or is unsuitable
for any other reason."

I'd argue that it is not normal behaviour but a missing feature or a
bug, depending on how you look at it.

imho it's clearly a nova shortcoming.

if nova doesn't want this to be fixed please close it as "won't fix"
instead.

thanks.

Title:
  Static Ceph mon IP addresses in connection_info can prevent VM startup

Status in OpenStack Compute (nova):
  Confirmed
Status in nova package in Ubuntu:
  Triaged

Bug description:
  The Cinder rbd driver extracts the IP addresses of the Ceph mon servers from the Ceph mon map when the instance/volume connection is established. This info is then stored in nova's block-device-mapping table and is never re-validated down the line. 
  Changing the Ceph mon servers' IP adresses will prevent the instance from booting as the stale connection info will enter the instance's XML. One idea to fix this would be to use the information from ceph.conf, which should be an alias or a loadblancer, directly.
