I don't know the answer to your question, but I found this regression in
functionality was caused by the following commit:

  commit cf31b789927cedfd08c67dcf207b4a10ce2b1db6
  Author: Monty Taylor <mordred@xxxxxxxxxxxx>
  Date:   Sun Jun 3 13:03:21 2012 -0400

    Finalize tox config.
    
    Shrink tox.ini to the new short version.
    Fix the test cases to be able to be run in nosetets plus the
    openstack.nose_plugin, which finally removes the need for
    nova/testing/runner.py
    Also, now we'll just output directly to stdout, which will
    make nose collect the trace logging directly and either output
    it at the end of the run, or inject it into the xunit output
    appropriately.

Before that commit, it was possible to just invoke something like

   ./run_tests.sh -N -P test_libvirt

from the nova top level GIT directory to run an individual test suite.

Regards,
Daniel
