What about:
- letting "-cpu foo,+emulatedfeature" just work

unless emulated=yes
How about we remove the emulated=yes from this list? Then I'm happy :).
So:
- "-cpu foo" doesn't enable any emulated feature
What if "foo" already has movbe in the CPU model definition?
It will be disabled.
- "-cpu foo,+movbe" does
What if I want movbe enabled if and only if it is _not_ emulated?
Pick a CPU model that has it.
The whole point here is to never ever ever enable an emulated feature
unless it was explicitly what the user wanted.
"+foo" could be enough.
"nice and descriptive message" needs to be better specified. Messages on
stderr are useless for management software.
I'm not sure this feature is for management software users.
