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.
