Which layer are you exactly talking about ? Tha layer in RTEMS to be
executed as a guest OS ? Can you be more specific ?

Also, please be more specific : are you talking about the BSP and
device driver development from RTEMS or POK ?
So, I think you should consider another way : what is the basic
example and what do you need. Please consider a basic example and
asses what services are required to run this example. For example,
consider a simple system that executes two RTEMS instances on top of
POK hypervisor (the POK kernel, not the libpok part).

I do not think we should consider these issues now. The better is to
start with a basic example, make a prototype and go ahead. So, I
suggest you make such an example and then, we can discuss further
