Thanks for reporting this bug. If you check ifconfig you'll notice the hwaddr also changes. You can specify an hwaddr in the config file with
lxc.network.hwaddr=16:73:40:b3:ef:f5 Should we simply auto-generate an hwaddr (if none is specified in the optional user-provided config file)? ** Changed in: lxc (Ubuntu) Status: New => Confirmed ** Changed in: lxc (Ubuntu) Importance: Undecided => Low -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/931229 Title: lxc containers do not retain configured ip on container reboot To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/931229/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
