I've had success declaring a bridge in /etc/network/interfaces:

    iface br0 inet dhcp
        bridge_ports eth0 # this is your VM Ethernet

and launching my containers with:

    $ cat /etc/systemd/nspawn/container.nspawn
    [Exec]
    Boot=yes

    [Network]
    Bridge=br0
    $ sudo machinectl start container
