    alternativly a pci rescan could be forced.

  They fail while waiting for the attached volume to show up on the guest, and it never does.

  There are only 11 hits in the ceph jobs in the last 24 hours but
  that's still pretty high. The ceph xenial job which runs on newton,
  ocata and master is non-voting so people probably aren't noticing, but
  the ceph trusty job runs on stable/mitaka and is voting and is
  failing.
