Firstly VirtualBox is simply fantastic. I’ve been using Parallels on OSX and it beats it hands down, even with less RAM.

I have a small issue. I’m using VirtualBox on Ubuntu and virtualising the VPC images made available by Microsoft here for browser testing purposes. http://www.microsoft.com/Downloads/details.aspx?FamilyID=21eabb90-958f-4b64-b5f1-73d0a413c8ef&displaylang=en

Everything works really well but if I try to add more than one of the XP images to the virtual media manager I get the following error.
