I can't see any reason why you would want to do it
If you had read the URLs I supplied (and the links therefrom) you will see that you *can* boot an existing setup using a hypervisor - with limitations. It *is* possible to make the existing installation aware of the differences in the virtual hardware, or adjust these - including the NIC MAC. I admit - it's not simple - but it can be done, according to these postings.

Why would I want to do it?
  • Because I have an IBM desktop with the usual arrangement of recovery OS supplied on a protected partition. I don't have a full set of installation CDs, so I can't use my method 1.
  • Because very comprehensive and useful software for maintaining the system, including updating the BIOS, is included with the machine - but it only runs under native Windows.
  • Because before I commit totally, I need to ensure that all of my attached devices (USB etc.) and applications will work in the virtual space - currently they don't and I have to reboot. Which is a pain.
