As noted in [0], SeaBIOS (QEMU default) makes a mess of the terminal, qboot does not. It turns out this is actually useful with kunit.py, since the user is exposed to this issue if they set --raw_output=all. qboot is also faster than SeaBIOS, but it's is marginal for this usecase. [0] https://lore.kernel.org/all/CA+i-1C0wYb-gZ8Mwh3WSVpbk-LF-Uo+njVbASJPe1WXDURoV7A@mail.gmail.com/ Both SeaBIOS and qboot are x86-specific.
