I actually have a 4-level system:: HyperVisor is the only layer that is not
allowed to crash (RISC-V calls this machine). Progressing towards less privilege
is GuestHV, GuestOS, and Application. Hypervisor provides only memory, timing,
and device identification services. GuestHV provides what most would call the
HyperVisor, GuestOS woudl be LINUX, and everybody knows what an application is.
