virtualbox.org

I've partitioned my HD and installed Windows XP via BootCamp.
I don't want to reinstall it and all it's windows apps in a virtual disk, I want to virtualize this installation in my Mac.
So the question is:
can I virtualize a Windows XP already installed via BootCamp, using Virtualbox?

Since this question and potential answer is irrelevant to everyone except other users of a Mac host, perhaps if would have been better for you to ask it in the Mac hosts forum. Here, it is off topic IMHO for the reason I just gave. In any case, practically speaking you are more likely to find Mac expertise in an appropriate forum.
