I retried and checked 'podman info --format {{.Host.NetworkBackend}}', which still
reported 'cni'.

So I changed the containers.conf and specified netavark as network_backend in the
Network-section.

Afterwards 'podman info --format {{.Host.NetworkBackend}}' reported 'netavark'.

Now a dns-server is active in the network, but the other pods attached to the network
still can't be resolved. But this may be just some config issue. I will check.
