I would like to know if anyone has considered a virtual KVM [1] that
would let you switch between two operating systems, such as Linux and
Windows. The goal would be something that is faster than dual
booting. An option would be to hibernate the OS, and recover the
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.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

What about alternating the two OS's from hibernation?

Or have the processor only use half of the memory at a time, depending
on which OS you are currently working with.

That would only solve the system RAM problem. How about the
rest of the highlighted line above. If each OS thinks it's
the only OS on the machine, access to peripheral devices and
disks is going to be a problem. Here are a few samples:

- In what state did the other OS leave the serial port
link to the missile launcher?

- Both operating systems try to cache and modify disk
blocks, causing massive filesystem corruption.
