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 ;-))
