For the record: I turned /etc/init/lxc-net.conf into a shell script that you call with "start" or "stop". With that we can keep the logic in one place, and the upstart/systemd/init.d script would just call this. That sets up the lxcbr interface etc. I also ran the apparmor bits from /etc/init/lxc.conf, but even that isn't enough:

It might behave slightly differently when running under systemd. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1312532 Title: [systemd] Container startup fails on missing lxcbr0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1312532/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
