What I figured out. It happens in intersection of 3 features: *irq time accounting *stolen time accounting *linux guest with tickless idle only (not fully tickless) Looks like timer interrupts storm is happening during this benchmark (with 2:1 cpu overcommit). irq time accounting gets crazy. Even 'top' shows weird statistic: 50% hi, 50% st, ~0% user, spinning processes use ~0% cpu - that is not correct.
If this is the desired behavior or something need to improve? Regards, Wanpeng Li -- 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
