Hi!
I'm trying to port an OSEK OS to L4. I know that a guest OS runs as a L4 process from Fiasco's point of view. But I have also noticed relevent APIs such as the l4vcpu_* family, VM API for SVM, VMX, and TZ, and the vCPU API of threads.
My questions are as follows: 1. What are the differences between a VM and an ordinary process? 2. Is it possible to run a guest OS without utilizing VM/vCPU APIs? 3. What does a guest OS have to do in order to run on L4Re and Fiasco? Is there a guide for doing this?
I'm new to L4 and probably need concrete instructions.
Thank you in advance!
