yes, it's working like that

Don't work.

But no problem, define it in modprobe.d is the right place.


BTW, what is the best timeout for the watchdog ? 
I think that pve ha manager wait for around 1min before migrating vm ? 
if yes, the watchdog timeout should be lower ?


Another question, I have done some tests 2weeks ago with a customer,
and I think I had some problem, if the node reboot too fast 
(pve-ha-manager see the node down, but it's coming up again before the vm was migrated).
Is it a known bug ?
If yes, maybe forcing a shutdown/halt and not a reset/reboot of the node is better ?

AFAIK the suggested way is to add an option line to 

/lib/modprobe.d/aliases.conf 

or some other modprobe config file. For example I use: 

options softdog soft_noboot=1 

for testing. But I guess you can also add it to /etc/default/pve-ha-manager: 

WATCHDOG_MODULE="ipmi_watchdog timeout=60" 

(I have not tested that)
