Please note I said "as good if not better". In my experience with vmware and virtualbox, I have had more issues with vmware than with virtualbox. Again, YMMV - and clearly you've had better experience with vmware than virtualbox - that's cool with me :) > For example, under vmware you can run ANY operating system that runs on > i386 platforms with more performance than virtualbox (included > unsupported operated systems), with virtualbox not. Mac OSX runs on vmware now? ;) I joke! Well, as for compatibility with guest OSes: http://www.virtualbox.org/wiki/Guest_OSes It's not a whole lot of systems that don't run on VirtualBox. Generally I use VirtualBox for windows XP and linux systems I wish to try out for curiosity's sake. For these purposes, virtualbox works amazingly well for free software :) Also, I would think performance is a moot point when it comes to Virtual Machines, particularly if you are using something like virtualbox (or whatever vmware's equivalent is.. vmware player?). > And about using USB passthrought and 3D support.

I'm not doubting it is. :) I simply wanted to give voice to an open source alternative to vmware. -Chris
