[libvirt] NMI watchdog issue

Hi All, We are testing the upstream KVM with : Kernel, Qemu, Libvirt, Virt-Manager is built from the source (git). kernel version : 3.9.0+ qemu version : QEMU emulator version 1.5.0 libvirt version : 1.0.5 virt-install : 0.600.3 I have followed the below steps to test the NMI watchdog feature : 1. Installed the watchdog rpm on the guest 2.Booted the guest with qemu-system-x86_64 vm1.qcow2 -smp 2 -enable-kvm -m 1000 -cpu Nehalem -watchdog i6300esb -watchdog-action reset 3. Edit the grub.conf with nmi_watchdog=1 But, I see "cat /proc/interrupts | grep -i nmi" the nmi counter is not getting incremented. It would be helpful if you let me know whether it is a bug or I am missing some steps. Thanks, Chandrashekar
