hi everybody

I'm testing Qemu's watchdog.
My understanding was that hardware (here qemu's watchdog)
would take
action(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'/>
     </watchdog>

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