Thank you for the input everyone. I've tested XenAdminQt and it sees iso library, thank you for advice! Reason for using XCP-ng center is ease of use/simplicity during quick testing deployments in comparison to XO.

@olivierlambert done.

Amazing timing. I have been having this issue with a VM I just set up and I came here to find out if this is a known problem, only to discover that the 97 patches I have been planning to install tonight are going to fix it.

This was related to a very large number of snapshots attached to the VMs. This was cause by a bug with backup not cleaning up snapshots if an iso was attached. I was told this was fixed with the latest update.

@alcoralcor Thanks for the info. I thought maybe I was using too many disks, so I've tried creating disk groups of 3-4 drives with the same issue.

@Pilow While that could be true only 1 vm was shuffled to another SR. But all VMs now being backup with CBT enabled. Well... i just check again at backups and after the last scheduled backup at 1am all vms fell back to full backup again.

@dinhngtu Looking forward to that! I'll stick with the Rust guest utilities for the time being—hope to see that new release soon!
