This is the approach I believe was agreed upon during the last QEMU developers conf call (sorry I didn't join, the meeting timezone change confused me).
Some may notice that representing this new behavior using solely default values on CPU properties may be a little difficult. Making it possible to replace x86_cpu_compat_disable_kvm_features() with compat_props entries may be an interesting problem, too.
