I have filed the following bug for watchdog:

NMI watchdog fails to increment the NMI counter in /proc/interrupts

Kernel Version: 3.10.0-rc5+
Libvirt Version: 1.0.6
Qemu Version: 1.5.50

Steps to reproduce the issue:

1. Booted the VM with :
qemu-system-x86_64 VM1.qcow2 -enable-kvm -watchdog i6300esb -watchdog-action reset -smp 2 -m 2000
2. Edit the /boot/grub/grub/grub.conf with "nmi_watchdog = 1" before the initrd image.
3. Restart the guests, the NMI counter in /proc/interrupts was 0
4. Installed the watchdog rpm and ran chkconfig watchdog on
5. Restart the guest, even then the NMI counter did not increment
6. Changed the /boot/grub/grub/grub.conf with "nmi_watchdog = 1" to /boot/grub/grub/grub.conf with "nmi_watchdog = 2"
