--- features: - | Added a neutron check for ML2/OVS and ML2/OVN presence at the start of deploy phase. It will fail if neutron_plugin_agent is set to ``ovn`` and use of ML2/OVS container detected. In case where neutron_plugin_agent is set to ``openvswitch`` the check will fail when it detects ML2/OVN container or any of the OVN specific volumes.
