<p class="MsoNormal">unfortunately Neutron at the moment supports only a single plugin for each service. This means you can only specify a single core_plugin.<o:p></o:p></p>

<p class="MsoNormal">If your goal is to support multiple backend technologies in your deployment, you should perhaps have a look at the ML2 where deployment of multiple drivers should be possible.<o:p></o:p></p>
