So you're using --network-veth when you launch the container? As far as I can tell, you
don't need a tap interface at all; that will be handled automatically by systemd.
I think all you need to do is create the bridge br0, binding the physical interface enp7s0 on
its own (a bridge containing only the host's adaptor). Then, you launch the container with --
network-bridge=br0. That will automatically add the container's interface to the bridge.
I'm not sure if the container will be aware of the bridge's IP address at this point. I'd want to
check with the "ip a" command to see if it's listening on the same IP address on host0 and
check to see if it has connectivity before assigning an IP to the host0 interface inside the
