We've talked in the past about having an accelerator specific

solve the problem for ARM and for PPC.
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.
That said, why is mac99 the default?
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.
