Hi all,
I'm trying to load and run two linux kernels simultaneously; trying to
demonstrate virtualization as a first step.
Anyone have pointers to where I can start? I looked into plex, bochs,
vmware, usermode linux.. they only simulate an architecture upon which
another kernel runs.
My intentions are to give control to both the kernels to directly control
the hardware and do "context switch" between those two based on
time-slice.
Thanks in advance.

Maybe you could have a look at Adeos: http://home.gna.org/adeos/

Have a look at Xen: http://www.cl.cam.ac.uk/Research/SRG/netos/xen/
They don't really allow direct hardware manipulation but use drivers
of their own.

A first step towards what?

These are hosted (well, vmware has non-hosted products too). But as a
first step, this could be sufficient.

Even with a non-hosted virtual machine, you'll need a hypervisor. Take
a look at Xen (if you're using x86). Or get some time on an S/390 ;-))

Search for xenolinux.

For 2.0, they allow direct hardware manipulation.
