I think I'm gonna go ahead with Qemu. Bochs seems to be to slow for my purpose. I was wondering if you know which windows XP versions have been know to work? Also do you have any performance metrics on popular applications runing under qemu(ex. apache)? I guess it's in the usenix paper, but i can't download it.
