VirtualBox, VMWare, XEN etc are no emulators but virtualization managers.

If they would emulate a CPU they would be by far too slow to be useful. 
They just force the guest processes (in fact the OSes) to call the 
virtualization code instead of accessing certain hardware resources 
(such as peripherals and  memory management). But the 99,9% of the code 
of the OSes (and 100% of the code of the user processes) is executed 
just in the normal way.
