I disagree. We shouldn't present users with a situation where qemu-system-x86_64 binary A has a default of "pc" and qemu-system-x86_64 binary B has a default of "microvm", just because of the way they happened to be compiled. That seems liable to lead to confusion. (In general I think that default machine types are not a great piece of UI which we mostly have for historical reasons and because all x86 machines look very similar.) -- PMM
