I'll give VMware workstation a try, I forgot they also had a Linux version. Good to know about KVM and Xen having that option too. Willing to sacrifice a video card slot for that if I do find myself needing it more.
Audocad was a bad example given I had not tried it, just assumed if sketchup did not work, that would not work either, but I just tried it for fun and it actually DOES work, so that's good. I can always give up Sketchup and just stick to AutoCAD. I don't really use CAD that often but it is useful when planing a home project or something.
