I would recommend you check out the work of the Barcelona project,
headed by my Sun Labs colleague Grzegorz Czajkowski:


The idea, in a nutshell, is to run a single VM image, essentially *as*
the operating system, introducing a new Java concept ("Isolates") to
serve the rule of OS processes.

I hope you find this interesting...
