This is a static function which is not used anywhere yet, you need to
move its definition to the patch which will make use of it. Otherwise
libvirt would fail to compile at this point. Remember the goal is to be
able to compile (and check + syntax-check) libvirt after every single
commit. It's not enough if it compiles at the end of a series.

I would call this variable 'ret' since it is only used to steal the
pointer from machine_model and return it. Then, you can even do
s/machine_model/model/ if you want.

Otherwise the patch looks good.
