I've got windows Vista installed inside Virtual Box on my Mac OS partition. I've also got it installed under boot camp and I occasionally boot to it when I want to run windows with better performance and I don't need to run any mac apps. Unfortunately, all the data and apps in the 2 windows vista's are completely different.

Is there a way to share the installation of vista between the 2 ways of running it?

Edit: I found a forum post about running XP, but it turned into a long list of "I tried this, and it didn't work" and ends inconclusively.

This is a feature supported by VMWare Fusion and Parallels, however VirtualBox does not support it at this point in time, most likely because they are using the same codebase cross platform.

I am not aware of future plans to include this. The only alternative is to create a Virtual Machine from the Bootcamp partition and then remove Bootcamp if you don't need it.

This works with both Parallels Desktop and VMWare Fusion.

You asked about Virtual Box but perhaps the other two are an option as well?

I have a MacBook set up to boot into either Snow Leopard or Vista and the installed Vista on the Boot Camp partition also runs within Parallels Desktop.
