After examining that commit I discovered that the old testing/runner.py
file have a bit of magic to auto-prefix nova.tests onto any args:
# If any argument looks like a test name but doesn't have "nova.tests" in
# front of it, automatically add that so we don't have to type as much
for i, arg in enumerate(argv):
if arg.startswith('test_'):
argv[i] = 'nova.tests.%s' % arg
Since we lost this, you now have to fully specify the names of the
individual tests you want to run. eg this works for me:
./run_tests.sh -N -P nova.tests.test_libvirt

Daniel
