Only if you were using "-cpu somethingThatHasAVX", though, no?


Yes. The same argument goes the other way around. I want to use AVX
emulation, do "allow-emulation" and suddenly I get MONITOR/MWAIT emulation.


What about:

- letting "-cpu foo,+emulatedfeature" just work

- adding emulated=yes that blindly enables all emulated features
- making "-cpu ...,check" prints a warning for emulated features unless emulated=yes
