Hi Guys, I found below patch for KVM TSC trapping / migration support,
https://lkml.org/lkml/2011/1/6/90 It seemed the patch were not merged in Linux mainline. So I have 3 questions here, 1. Can KVM support TSC trapping today? If not, what is the plan? 2. What is the solution if my SMP Linux guest OS doesn't have reliable TSC? Because the no TSC trapping support, will kvmclock driver handle all TSC sync issues? 3. What if my Linux guest doesn't have kvmclock driver? Does that mean I shouldn't run TSC sensitive application in my guest OS? BTW, my application is written with lots of rdtsc instructions, and which performs well in VMware guest.
