I think that if you want to run Neutron-networked Docker containers on
an OpenStack VM, you'll need OpenvSwitch and neutron-agent installed on
that VM as well.

A better-suited approach would be to run K8s on OpenStack and use
kuryr-kubernetes instead. That way Neutron subports are used to network
pods. We have such a K8s-on-VM use case described in the docs [1].
