As such, only QEMU or VMWare Player/Server can be used to run unmodified guests. (Read: Windows) Both are free. QEMU is slower, but GPL. VMWare is (much) faster, but it's close source and as such, if it breaks, your own your own. * - Gilboa * Though in my experience, VMWare server is pretty stable.
