I would like to know if anyone has considered a virtual KVM [1] that

Windows. The goal would be something that is faster than dual

alternate OS from hibernation. Even crazier would be to use a multi-
processor CPU for such, so that switching between desktops would be
instant.
[1] perhaps built into the BIOS? Any open source BIOS's?
What this would mean is that Linux wouldn't have to replace windows
to compete with it: it could take over gradually. Free, as in beer.
A virtualizer is a good idea. That's why they have been developed and
deployed. VMWare is one of them. Perhaps it would be beneficial for
you to become acquainted with what's already available.
If by using "a multiprocessor CPU" means have one operating system
running on each processor, I'll agree that _is_ a crazy idea. It's so
crazy the reasons it is not practical have already been discussed.
Some of the issues include who manages system RAM, peripheral devices,
disk space, etc.

(Yes, that is one of my email addresses.)
What about alternating the two OS's from hibernation?
When you run Virtual Machines some or all of the of the virtual memory
from an idle VM will be swapped out of physical memory if it is needed by
an active VM (just like it would be for any idle process), of course if
that happens you should buy more RAM because swapping indicates that you
don't have enough memory. CPU resources are also allocated as needed
(which is also what happens with multiple processes on any modern OS).
VMs allow you to run multiple OSes simultaneously. They are all present
at the same time and they share the available resources. VMs are the
modern way of doing this. What you are proposing, a Virtual KVM, would be
like going back to DOS where only one program could run at a time.
Somebody at OpenBIOS suggested this:

Any others worthwhile?
On Wikipedia it says Xen just got bought out by Citrix, which has
agreements with Microsoft. Just how much influence does Microsoft
have on Citrix? Microsoft can make somebody's stock plummet just by
looking at them.
