I am researching ideas for a PhD project.
One of my thoughts is writing a hypervisor (or bare metal) (?) so I could run multiple OS's without use of a true host operating system. Example I get a menu of some type of options to start operating systems, view what the 'console' of what is going on in an OS that is already running. Reboot OS's, install a new one, etc.
So no host OS, just a small app that controls everything.
Conceptually how does one think about doing this?
I have a MacBook. I should be able to modify what the EFI boots. Maybe start with a very minimal Linux LIve implementation and scale it really, really far back?
Is it possible to use Darwin and scale it very far back?
