CPU models past gen16a will no longer support the csske feature. In order to secure migration of guests running on machines that still support this feature to machines that do not, let's disable csske in the host-model.
Sorry to say, removing CPU features is a no-go when wanting to guarantee forward migration without taking care about CPU model details manually and simply using the host model. Self-made HW vendor problem.
And this simply does not reflect reality. Intel and Power have removed TX for example. We can now sit back and please ourselves how we live in our world of dreams. Or we can try to define an interface that deals with reality and actually solves problems.
Ehm, so, I spell out the obvious and get such a reaction? Okay, thank you. See my other reply, maybe we want a different kind of "host-model" from QEMU. It's Friday and I'm not particularly motivated to participate further in this discussion today. So I'm going to step away for today, please myself and live in a world of dreams. -- Thanks, David / dhildenb
