I am a university student who want to build a Hypervisor by Rust on aarch64 as my final project. At first I want to build the one who worked in SEL2. However, I find it difficult for me to build such hypervisor for I am confused about the difference between these two level.
I have known that SEL2 is in the secure world. And it can support the hypercall too. I also know there is a hypervisor called hafnium. But I still be confused about the detail knowledge. I wonder know the detail document and resource that I can find to learn about it.
Or maybe it suitable for me to build a embeded Hypervisor? I feel confused.
Actually, I wanted to write a Rust OS but my tutor want me to build a Rust Hypervisor for there are too many people work in Rust OS.
For a final project I would leave "S" aside. A non-secure hypervisor is complicated enough. And you cannot do it in Rust alone, you will need assembly!
Thanks for your reply. Aactually rust has a rust-vmm. I don't want to build all the components by myself so I will try to use the rust-vmm to simplify my design, but I am not very sure if this can work. I think fail to wrtie a "S" one maybe a good choice.
