You can list the network namespaces from a network node or the openvswitch_vswitchd container, but namespace management operations, such as using the ip netns exec command, fail with a Invalid argument error message.

Network namespaces are managed from the neutron_agents container. Run the following command to access the container before performing any network namespace management operations:

$ docker exec -ti neutron_agents /bin/bash
