Ah, this looks like a good idea (and we could even generate that file
dynamically if we add support for family/stepping/... and other things that we
do not model now). However, separating these definitions from qemu may result
in incompatibilities with older qemu versions. I guess mainly because our
configuration file would mention a CPU feature that an installed qemu version
doesn't understand. Currently, qemu seems to just ignore such feature
(although it prints an error) and continues happily without it. Is there
any way for us to ask qemu what CPU features it knows about so that we could
avoid using a CPU models which include features qemu doesn't understand?
