VirtualBox: how to start and shutdown guests VMs on startup
 

I'm preparing a vitualization server (host) with VirtualBox. This machine, running Debian, is intended to run in HeadLess mode, without GUI.
I've got some guests VMs running. But I was wondering about the best way to start this guests VMs on startup and shut them down kindly when host is shutdwon.

Virtual Machines run under non-root user. I was thinking about making a script in /etc/init.d/ in order to start certain VMs and to stop every VM running when system is halted. Is this really the simplest and most secure approach?
Actually I couldn't find very much on this subject in user manual or googlin' around.

Thanks in advance for any help,
Matías

Catkin,

Thanks a lot. The example helped so much to make my own startup / shutdown scripts.

Glad you found a solution and thanks for marking the thread SOLVED.

As you found out, it is difficult to find examples of VirtualBox VM startup / shutdown scripts on the 'net -- so it might help someone if you posted yours here :)
