hi everybody, I tried to get a help on libvirt mailing list but not luck, I hope maybe here?

I'm trying Qemu's watchdog.
My understanding was that hardware (here qemu's watchdog) would take action, eg. cold reboot) the system if there is no ping from the OS watchdog, so I
thought stopping watchdog service in VM should be a quick test.

I have this in the guest:

    <watchdog model='i6300esb' action='reset'>
<address type='pci' domain='0x0000' bus='0x00' slot='0x08' function='0x0'/>

and I see /dev/watchdog in my guest. Yet nothing happens, guest runs uninterrupted. I must be missing something, an expert said it's config problem?
many thanks
