 #. Some health checks are expected to fail due to the default networks and routers created during the deployment being deleted, after PLUMgrid plugin is installed. These are created before PLUMgrid is enabled as the network backend, hence the PLUMgrid ONS platform has no knowledge of these previously created routers/networks and they are therefore removed.
