I'm running Ubuntu 11.04 with VirtualBox and a Windows XP VM. This VM has Office 2007 installed on it. How can I use Guest Controls so that Office files (
.pptx, etc.) open in Office on the VM when launched from Linux?
As far as I know, this feature is not available in Virtual Box (at least I cannot find documentation relating to it.) It is available on other platforms, like Parallels on OSX and it's called Shared Applications.
It appears you can do what you suggest, but it will require some finesse and bash scripting
Have fun! Let us know what you come up with.
