 ### Special thanks:
 * The creators of VirtualBox for making it open-source and kind of easy to use (though I had minor issues as the documentation doesn't really tell me how to write a new frontend :P and that I needed to learn how machines work - especially keyboards)

+**Fix:** Close all VirtualBox instances and wait 10 seconds.
