My hypothetical script which iterates over models in that way is a
"management tool", and would use qemu to help do its job.
Do you mean that more powerful management tools to support safe
migration will maintain _their own_ processor model tables, and
perform their calculations using their own tables instead of querying
qemu, and therefore not have any need of qemu's built in table?
If so, I favour more strongly Anthony's suggestion that the processor
model table lives in a config file (eventually), as that file could be
shared between management tools and qemu itself without duplication.
