"-cpu best" is different from the modes above. It means "use the best existing CPU model (from the pre-defined table) that can run on this host".
Yes, it's not exactly the same. In practice the behavior should be close.
And it would have the same ambiguities we found on "-cpu host": if a CPU model in the table have invtsc enabled, should it be considered a candidate for "-cpu best", or not?
No CPU model in the table should have invtsc enabled. :) Paolo
