Yes, that's the fix I'm talking about. I'm going to mark this bug as
invalid since it has already been fixed.

** Changed in: nova

Title:
  confirm-resize failed, after migration. "KeyError:
  'old_instance_type_memory_mb'"

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  confirm-resize failed, after migration. "KeyError: 'old_instance_type_memory_mb'"
  Because after migration (Not resize), no "old_*" information exist in sys_meta. (old_* and new_* both exist only after resize operations)
