Looking through the commit history, I see: kvmclock: Ensure time in migration never goes backward kvmclock: Ensure proper env->tsc value for kvmclock_current_nsec calculation Assuming those are the right fixes for this issue, are they suitable to request backported to distros' qemu 2.0 branches? The merge commit for them seemed to indicate they were problematic at first. On second thought - I found the qemu-devel threads about reverting them in the 2.1 timeframe, so I'm going to do a little more research before I start trying to suggest how to fix for existing install-base. -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
