The performance gain will be important, especially for purely 
computational user tasks (close to native performances). The OS kernel 
itself will run at about the same speed as the 'standard' qemu.

To do better, a host kernel module will be needed, but I don't have the 
courage to do that yet.

Yes, it is better not to ask :-)
