Yes I know it emulate HW at low level and special VM drivers are needed. But I had something different in my mind. Do you know how hardware CPU Virtualization support helps the VM software? What is the difference if VM runs on old CPU without HW virt. support and with it? If it also would help under d dos e.g. for IO or memory trapping or better/faster service handling...

Yes AFAIK it's not virtualized but I meant it just for real DOS.
