--- features: - | Some scenario tests require advanced ``Glance`` images (for example, ``Ubuntu`` or ``CentOS``) in order to pass. They are now skipped by default. If you need to execute those tests, please configure ``tempest.conf`` to use an advanced image, and set ``image_is_advanced`` in ``neutron_plugin_options`` section of ``tempest.conf`` file to ``True``. The first scenario test case that requires the new option set to execute is ``test_trunk``.
