Code review comment for lp:~vishvananda/nova/no-db-messaging

Ran into a test failure:

======================================================================
FAIL: test_create_and_delete_volume (nova.tests.integrated.test_volumes.VolumesTest)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/home/rick/openstack/nova/no-db-messaging/nova/tests/integrated/test_volumes.py", line 122, in test_create_and_delete_volume
    self.assertEquals(1, len(create_actions))
AssertionError: 1 != 2
-------------------- >> begin captured logging << --------------------

Other than that, I think this looks good.
