Auto shutdown KVM Virtual Machines on system shutdown

Update August 2010: It does not always work as expected. Though this method works well if the server is Ubuntu 8.04 or Ubuntu 9.04, but the shutdown script never get called in Debian Squeeze. Maybe a better init script would be required for newer versions.

Though the initial use was on the servers which were rarely shutdown, now I’ve started using it in my home envir0nment where frequent restarts or shutdowns are there. The challenge that I faced was to automatically shutdown the KVM virtual machines when the system was shutdown or restarted.

  2. Make sure you are able to do ssh without entering any password from root into the VMs
  3. Put the script into the /etc/init.d directory.

  5. Reboot the system to check if it worked
