No, the KVM guest ist not running in parallel. But I'm not able to clearly reproduce the NMI messages with "perf record". I start "perf record -a" and after some minutes I stop the recording. After that it seems NMI messages appear within a random period of time. So, I cannot tell what triggers the messages. -- 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
