Hmm, that's surprising, it definitely works fine on Ubuntu. My guess is that you're missing the upstart job which reacts on SIGPWR being received by PID1. Try adding this as /etc/init/shutdown.conf in your container: """ # Trigger an immediate shutdown when upstart receives SIGPWR # this is useful for some UPS monitoring tools and for clean # shutdown of containers description "Trigger an immediate shutdown on SIGPWR" start on power-status-changed task exec shutdown -h now "SIGPWR received" """ After that lxc-shutdown should work fine. -- Stéphane Graber Ubuntu developer http://www.ubuntu.com
