Okay. Let's just make sure to document -nodefconfig as version specific
and -nodefaults as the stable way to create a bare bones guest (and
define exactly what that means).
Agreed. But I do want to point out, that -nodefaults has not been stable and
since it doesn't universally create a bare bones guest, it's not clear that it
will be.
I think what we want to move toward is a -no-machine option which allows a user
to explicitly build a machine from scratch. That is:
qemu -no-machine -device i440fx,id=host -device isa-serial,chr=chr0 ...
