It looks like only -device would be able to create actual CPU models, but for -device to work we need as minimum this series and conversion of CPU features to properties in tree. Then I guess we can override cannot_instantiate_with_device_add_yet for x86 CPUs. Setting cannot_instantiate_with_device_add_yet=false looks much simpler than implementing UserCreatable. My question is: may we do that, already (once this series gets included), or is there something else holding us from doing it?
Once you make something creatable with "-object", the API must not change anymore. So we would have to think twice about that. Allowing -device may be okay, since in the (very?) long term -device can be replaced by -object. But -object is definitive. Paolo
