For ARM I would prefer not to have a default at all, and make
the next level up specify it. It's reasonable to have a default
machine choice for when you create a VM configuration; it's
not so sensible to have a default that's picked every time
you run the VM. The thing I think is most likely to be the
useful choice for KVM/ARM isn't even in the tree yet...

There's no user level difference between "pick whether you
wanted a model of a versatile-PB or a zaurus" and "pick
whether you wanted a model of an x86-PC or an ARM zaurus".
At the moment we require the user to specify the latter choice
(by having them in separate executables) but try to guess
the former.

Presumably because it was a sensible choice when it was originally
put in, and once you have a default you can't change it without
breaking peoples' command lines.
