Marking as Opinion as this bug discusses internal code structure changes
which are partially out of date. In future bugs that have a reproduce
would be more valuable.

Title:
  XenAPI: Consider removing safe_copy_vdi

Status in OpenStack Compute (Nova):
  Opinion

Bug description:
  safe_copy_vdi depends on ext3 and is not using supported interfaces,
  so should be considered for removal.

  It was added because the vdi.copy operation wasn't considered to be
  atomic.  However, VDI.copy is definitely atomic and will not return
  until the copy has finished.  It's therefore possible that the
  rationale for this function was based on looking at the SR during a
  copy operation, or use of async VDI copy.

  The reasons for this function need to be reviewed.
