Title:
  Periodic task cause errors in _finish_resize

Status in OpenStack Compute (Nova):
  Fix Released

Bug description:
  In the event that an end user sets resize_confirm_window to something
  small (say 1 in this example) there is a possibility that the periodic
  task can run in
  nova/compute/manager.py:ComputeManager._finish_resize() after the
  migration has been updated but before the instances has been updated.

  http://git.openstack.org/cgit/openstack/nova/tree/nova/compute/manager.py#n3570

  
  One possible solution to this would be to reverse the order, and update the instance before updating the migration, in which case the migration will get updated in _confirm_resize: http://git.openstack.org/cgit/openstack/nova/tree/nova/compute/manager.py#n5018
