John,
just two comments from skimming through the patch:

Wouldn't it be much more user friendly to merge them all into one
string? Just from the feature names it is quite obscure to guess which
flag belongs into which string (especially since we lack the EXTn_
prefix we had in helper.c). I haven't tried it, but the parsing code
looks like this shouldn't be too hard.
To avoid overlong lines one could think about a += operator.

I would just drop all definitions here except qemu{32,64} and
kvm{32,64}. The other models should be described in the config file.
Regards,
Andre.
