[arch-general] Bridge interface with netctl

[arnaud gaboury]

Dear list,

I am messing with assigning a static IP on a systemd-nspawn container,
on both sides (host,container).
My idea is to first create a bridge (br0) on the host.
My config on host :
systemd-git
netctl to configure network

gabx at hortensia ➤➤ ~ % cat /etc/netctl/bridge-hortensia
Description="Example Bridge connection"
Interface=br0
Connection=bridge
BindsToInterfaces=enp7s0
IP=no
*********************

Now, I want to start the bridge:
# netctl start bridge-hortensia
% ping -c 3 8.8.8.8
connect: Network is unreachable

Same result if I change IP=dhcp

I can't see where does the issue come from. Shall I enable a
"ethernet-dhcp" netctl profile and disable dhcpcd.service ?

Thank you for help.
