ok I can reproduce with just this shell script. The weird thing is, it only reproduces if I watch the log and kill the container after it fully boots.
cloud init will report that it is done booting like this: cloud-init boot finished at Fri, 05 Oct 2012 20:15:32 +0000. Up 200.15 seconds if you run the script, and wait until you see that message, then press enter, which triggers stop/destroy, the bug will reproduce on 3.6.0 upstream kernel [1] as well as quantal's [1] http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.6-quantal/ ** Attachment added: "repro.sh" https://bugs.launchpad.net/ubuntu/quantal/+source/linux/+bug/1021471/+attachment/3377289/+files/repro.sh -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1021471 Title: clone() hang when creating new network namespace (dmesg show unregister_netdevice: waiting for lo to become free.
