I can't reproduce this on an uptodate raring server. You filed this against qemu-kvm, but the bug is claimed against lxc. I will mark ti as affecting lxc - please then run 'apport-collect 1186501' to get some helpful debugging info uploaded to the bug.
It might also help to do a 'lxc-start -n <containername> -l info -o lxc.debug', then attach lxc.debug to this bug. ** Package changed: qemu-kvm (Ubuntu) => lxc (Ubuntu) ** Changed in: lxc (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1186501 Title: LXC won't tear down VETH device on shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1186501/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
