Hi Tobi, the idea is actually good, but my experience is that modern Linux distros are unable to shutdown with "kill -s INT/PWR".
I tested on Debian Squeeze and Ubuntu Natty and it didn't work. What distro are you using? Check this thread: http://www.mail-archive.com/lxc-users@lists.sourceforge.net/msg01797.html These are the ways to automatically shutdown a container cleanly I know so far: 1) use a patched kernel to fix lxc-attach behaviour https://launchpad.net/~serge-hallyn/+archive/lxc-natty/+packages lxc-attach -n vm0 poweroff 2) use ssh daemon inside container to shutdown 3) create a small unix domain socket that runs inside the container. Send special signal to the socket file from the host.
