A Type-1 hypervisor for the TB32 instruction set, built on the virtualization extension in libtb32. It runs unmodified TB32 guest operating systems, each isolated from the others and from the hypervisor by two-stage address translation.
zig build run # boot to the manager console
zig build test # unit tests
Requires Zig 0.13.
Single-key commands at the hypervisor prompt:
| Key | Action |
|---|---|
l |
list VM slots and state |
c |
create a VM |
k N |
destroy VM N |
N |
attach to VM N (console routed to that guest) |
i N |
show VM N's saved program counter |
Ctrl + ] |
detach (guest pauses, resumes on re-attach) |
q |
power off |
The bundled guest prints its id and echoes input; type x to make it exit.
tb32hv runs as TB32 code in a dedicated hypervisor mode over a small emulated machine. It gives each guest its own stage-2 page table and trap-and-emulates the devices the guest believes it owns, so unmodified guests run fully isolated. A guest cannot escape its partition because the final translation to host memory belongs to the hypervisor rather than the guest.
