Right. I am left after I boot my machine (the host) with this :

4: vb-dahlia: <BROADCAST,MULTICAST> mtu 1500 qdisc noop master br0
state DOWN group default qlen 1000
    link/ether 62:a2:6b:f4:0f:87 brd ff:ff:ff:ff:ff:ff

I have to manually
# ip link set dev vb-dahlia up

to get the network working on the container :

1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 5a:51:a2:a2:b5:fb brd ff:ff:ff:ff:ff:ff
    inet brd scope global host0
       valid_lft forever preferred_lft forever
    inet6 fe80::5851:a2ff:fea2:b5fb/64 scope link
       valid_lft forever preferred_lft forever

I will try your hack asap

Ah? I have two netctl profiles, one for my physical eth (enp7s0) with
no ip, one for bridge (br0) with enp7s0 binded to.
So you mean you don't have any bridge profile managed by netctl ?

 but I suppose that would also be possible to do with
