Hi Everybody,

 

I have built a new host which has been running fine for the last couple of days. I noticed today that the host crashed, but it is not giving me a reason as to why.

 

It happened at 13:45 today, but I have given time before that on the logs as well.

 

Is there something I am missing here?


Not related to the crash, but I see in the logs that 5 out of 20 guests have qemu guest agent not responding.

Also you seem to have some issues with some firewalld rules. (Maybe +Dominik Holler would like to have a look)

I don't see anything explaining why the host got rebooted.

Still related to guest agent I find a bit alarming the following lines:

+Arik Hadas any clue?

About the crash, can you please provide full sos report from the host? the log you provided is not enough to understand what caused the reported crash
