I am running VirtualBox on a dual-monitor Windows 7 x64 system. When I put a VM into full-screen mode it always appears full-screen on my primary monitor even though the VM window was on the secondary monitor. Is there a way to make it appear full-screen on the secondary monitor?
When you are in Full Screen mode in the view menu choose "Virtual Screen 1", "Use Host Screen 2"
While in fullscreen mode, press HostKey + Home to bring up the hidden menu. Select View -> "Virtual Screen 1" -> "Use Host Screen 2"
