<div>Even though the IPMI interface is on, the watchdog is disabled. I'd like to try with another hardware just to check, but right now I haven't got any. </div>

If it is the hypervisors rebooting, a possible scenario would be if you have a BMC and enabled watchdog. This will reboot the server if it does not call home to the BMC every 'n' seconds.<br>
<br>
If you have a very busy hypervisor, you may need to tune the watchdog timeout.<br>
<br>
I suspect something would be logged in the BMC ipmi sel logs but not sure.<br>
