@borzel Sometime between the 7:40 and 12:12 on the first line. I'm guessing it went down right as I was posting here. Like I said whatever it's doing it doesn't seem to log it. Is there any other log files I should check? EDIT: I have a theory, testing it now. EDIT 2: I'm wondering if this has something to do with XCP-NG Center. The KMS server (the one that locked up) was the only one I logged into when checking if everything was working. Trying to duplicate this now.

@atmurphy, I haven't tried it, but there are a set of plugins available for Xencenter that might work under XCP-ng Center that adds an auto-start option. See https://www.citrix.com/blogs/2018/03/14/xenserver-plugins-collection-v6/

That's mysterious Could we take a look at what you are doing? Could be interesting for the community!

One HDD was damaged, but all my VM was moved to a reseve Sever. So the easyest way was 2 install again. But the install scripts find sometimes one RAID 1 and the Disk behind the LSI RAID. It dont use the /dev/md127 and try to build a new RAID 1 with /dev/sdc and /dev/md127..... and sme craesy options too. Now i am erasing everything on the old HDD, now its running. The Problem with GDISK HDD are one the end of the HDD is a reseve partition tabelle. Most tools dont erase them. But it is very old and cytrix dont fix it. But its bad when you had fix somthing with booting teh hardware server with a live linux
