Technical feasiblility of a sandboxing Kernel

[zilmont]

What is the feasibility of a kernel that creates a sandboxed system to run other kernels. In a fairly simple concept you would split up system resources such as the ram and cores in your processor and dedicating them to each of the kernels running. I'm just wondering what kind of things you would need to take into consideration and whether or not it would be feasible to begin with.

These exist and are termed "hypervisors".

You've just described a basic virtual machine monitor. Writing one is about as difficult as writing a kernel I would say, so not recommended if you have little to no experience with that.
