You use Ceph as backend of Nova? or Glance? or Cinder? or a combination thereof? Does your instance use ephemeral storage or volume as root disk?

Have you checked all logs? I.e. Nova, Glance, Ceph, and (if applicable) Cinder? Perhaps you should look for WARNING or INFO in addition to ERROR.

I can't help you if I don't know for what you use Ceph (Nova, Cinder, Glance), and what the messages are.
