Comment 2 for bug 1179938

We're hitting this bug too:

  File "/usr/lib/python2.6/site-packages/nose/suite.py", line 208, in run
    self.setUp()
  File "/usr/lib/python2.6/site-packages/nose/suite.py", line 291, in setUp
    self.setupContext(ancestor)
  File "/usr/lib/python2.6/site-packages/nose/suite.py", line 314, in setupContext
    try_run(context, names)
  File "/usr/lib/python2.6/site-packages/nose/util.py", line 469, in try_run
    return func()
  File "/tmp/tempest/tempest/tempest/tests/network/test_networks.py", line 29, in setUpClass
    cls.network = cls.create_network()
unbound method create_network() must be called with NetworksTest instance as first argument (got nothing instead)
