Debugged on IRC. For the record, the link in /etc/rcS.d/*networking was missing. Hence the sysv-generator didn't create a networking.service and didn't attempt to start it.
I just created a fresh vivid container and the link does exist, and network is coming up fine for me. Can you reproduce this somehow? ** Changed in: systemd (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1439109 Title: Network interface not coming up automatically inside lxc container To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1439109/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
