The dmesg of the guest shows: APIC calibration not consistent with PM-Timer: 191ms instead of 100ms This should be a qemu-kvm bug. kvm + qemu-kvm = result 4f324a1b + b5ed4b6f = bad 4f324a1b + 9d636ae7 = good Reproduce steps: ---------------- 1. start up a host with kvm kernel 2. qemu-system-x86_64 –m 1024 –smp 2 –net none –hda /root/rhel6u1.img 3. cat /proc/interrupts Current result: ---------------- interrupt 0 keeps increasing Expected result: ---------------- interrupt 0 stops at some value and doesn't increase To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/979714/+subscriptions
