If so, presumably the > right solution is to expose it. KVM has the concept of a guest's invariant TSC frequency. The Maximum Non-Turbo Ratio is just some fraction of that. Sadly, the fraction is 100 MHz, 133.33MHz, or the "scalable bus frequency" from some other MSR, depending on microarchitecture.
