How to auto-shutdown guest when doing host shutdown?

im running netrunner x64 and i want to shutdown the virtual guest on virtualbox, when I shotdown netrunner

are there anyone who can tell me how to do that ?

If you choose shutdown on the desktop it should shutdown the virtual machine aswell.
This might however take a little while depending on the virtualbox version you are using.

No vitualbox blocks me from shutting down the system because i have a guest running

Which virtualbox version do you use ?
Iam using 4.3.10 here and it works fine.

Im using the same version

lockout canceled by /usr/lib/virtualbox
