In the Microsoft Developement Netowrk Level II DDK under ddk/docs, there is a file called vmm.doc. IBM published a VM document describing the OS/2 VM implementation. I don't know if you'd have to do a whole virtual machine manager (ala the Microsoft document) unless you wanted DOS sessions and the ability to run things like "Descent" in a DOS window on your X desktop, or display DOS text-mode sessions on remote X displays. Personally, I'm only interested in the driver abstraction capapbilities (for now anyway).
