Yes, this is working for me too.
The watchdog seem to works fine, simply not started ...

I had problem with watchdog on ipmi, that's why I uses for check next: 
ii  pve-manager                          4.1-5                          amd64        The Proxmox Virtual Environment 

check: ii status package and test watchdog: 

echo "A" | socat - UNIX-CONNECT:/var/run/ watchdog -mux.sock 

after this command, server rebooted

The problem is not that the watchdog is not trigger, 

is that the watchdog timer is stopped 
(and with a strange countdown of 15s) 


# ipmitool mc watchdog get 
Watchdog Timer Use: Reserved (0x00) 
Watchdog Timer Is: Stopped 
Watchdog Timer Actions: No action (0x00) 
Pre-timeout interval: 1 seconds 
Timer Expiration Flags: 0x00 
Initial Countdown: 15 sec 
Present Countdown: 15 sec 


I don't have any other external software installed which can stop or change the timer (like openmanage)

looks OK to me. Seems there is no HA enabled VM on this node? That 
would explain that the watchdog does not trigger.
