To be short: as some people already noticed, this option allows to run user code and most of the kernel code on "bare metal". The result is usually a noticable speed up. Only the following guest OSes are supported: Linux, Windows 2000 or XP. The installation of Windows 2000/XP must be run without the -kernel-kqemu option. I did not test the win32 and x86_64 versions of kqemu yet, but the i386 version is usable. Fabrice.
