Now, upon "systemctl restart systemd-networkd", "ip addr" show "br0" with the correct IP address but still "DOWN"!
----------------------------
4: br0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc noqueue state DOWN group default qlen 1000
[...]
----------------------------
I just tested netplan 0.39 on a 18.04 VM and it does not fix the problem, the bridge is still DOWN upon creation :-(
