The latest XCP-ng update had an update regarding NTP XAPI, XCP-ng's control plane, was updated to version 26.1.3. Added API for controlling NTP. This might be a longshot and I don't know it this has anything to do with my "problem" The timestamp on ContRep VM's has always been in UTC I'm using Stockholm SE as timezone and other bugs regarding presentation of time have been fixed but not this one,

@nikade I did install the 97 XCP patches and that night the VM that was failing to backup was able to successfully backup. It had a 500GB secondary drive that was formatted but totally empty. I had not yet patched my XO from source to the latest, it was maybe 24 commits behind. On Friday I updated it so I will find out on Monday if those backups continued to work but I assume they did.

@timemaster5 Ah very cool, thank you for looking into this and the comprehensive write up, great work. I went on a small journey to try various workarounds but didn't get as far as yourself and others, particularly as my use-case is only a "nice-to-have". Most everything I found was in relation to Proxmox and others. Little did I know when I thought I was helping you over on Github, you would actually end up helping me! As I understand from your notes, the full procedure would be: Enable passthrough for the GPU on the host Apply the patched wrapper to enable custom model args and respect platform vga Disable emulated VGA via platform:vga=none Apply the config to the VM via -device loader options Reboot the host Mount the GPU to the VM and boot it up

@AlexanderK Nested virtualisation still need lot of development to be functional reliably - see https://www.youtube.com/watch?v=8jKGYY1Bi_o and https://www.youtube.com/watch?v=3MxWvVTmY1s

@MajorP93 said: -disable HA on pool level -disable load balancer plugin -upgrade master -upgrade all other nodes -restart toolstack on master -restart toolstack on all other nodes -live migrate all VMs running on master to other node(s) -reboot master -reboot next node (live migrate all VMs running on that particular node away before doing so) -repeat until all nodes have been rebooted (one node at a time) -re-enable HA on pool level -re-enable load balancer plugin Never had any issues with that. No downtime for none of the VMs. update time again. and same issue I followed these steps -upgrade master -upgrade all other nodes -restart toolstack on master -restart toolstack on all other nodes -live migrate all VMs running on master to other node(s) -reboot master now cant migrate anything else. live migration : NOT_SUPPORTED_DURING_UPGRADE warm migration: fails and VM shuts down immediately and needs to be forced back to life CR backup to another server : NOT_SUPPORTED_DURING_UPGRADE
