[pve-devel] need help to debug random host freeze on multiple hosts

[Alexandre DERUMIER]

>>Maybe i ask you a silly question, did you see the syslog and kern.log file? 

Yes sure , I have nothing in logs.
(That's why I thinked of kdump to try to have more info).

I'll really don't known if it's a software real kernel panic, or a hardware bug.

I just see on vmware forum some amd microcode bug, and see that dell provide a new bios update this month.
I'll try to update to see if it's help.
