Cristobal Escamilla "I read all of those http://www.virtualbox.org/search?q=vboxmanage+registervm&noquickjump=1&ticket=on none of them apply. I'm trying to run a headless vm, so I'm using vboxheadless.exe but it can't find the vm as it says ""Invalid machine name!"", no wonder, the service is running as a different user. Then I told the service to also run '""C:\Program Files\Sun\VirtualBox\VBoxManage.exe"" registervm C:\Ubuntu.xml >> vbox.log' and I got this reply: VirtualBox Command Line Management Interface Version 3.0.12 (C) 2005-2009 Sun Microsystems, Inc.

I will attach the batch file, the output screen and the xml file. Please note that I will not remove the section even though I did remove the whole section.
