    @florent The following error occurred: Mar 16 18:38:10 XOA xo-server[4001]: 2026-03-16T17:38:10. 246Z xo:rest-api:error-handler INFO [GET] /vms/0691be81-7ce9-7dba-9387-5620f8e0c52f/vdis (404) XO version: Master, commit 15917 xcp-ng version: 8.3 with the latest updates. What’s interesting is that there are two xcp-ng servers, and the problem only occurs on one of them.

    @Dezerd you just have to start-copy the Replica VM it permits the original job to keep replicating on the VM. there is no failover/failback mecanism AFAIK if you work on replica started VM, you will have to put up in place a replica going to original hosts

    Version 1.4.0 is released: https://codeberg.org/NiXOA/system/releases/tag/v1.4.0 It includes significant changes and improvements, including: dedicated getting started section, migration to valkey, only needing to clone system, and helper scripts. the xen-orchestra-ce nixpkg now references the libvhdi nixpkg, and the core flake now references and pulls from the xen-orchestra-ce repo as an overlay. System (the user input flake) now uses the Core repo as an overlay, reducing the need to clone both locally AND allowing system to pull new updates and releases from core. XO, and libvhdi as needed. The next goal is: Make an xsconsole-like TUI Automate package updates for libvhdi and xen-orchestra-ce using CI/CD pipelines Submit libvhdi and xen-orchestra-ce as official nixpkgs

    Hi, I've noticed the addition of the commit about the 99 limit warning. That's good news. I am now having trouble trying to understand the meaning of the Full Backup Interval setting. I have the following scenario: Backups for the last 30 days, daily. Backups for the last 52 weeks, weekly. I want to make sure that the delta backups are not corrupt periodically (let's say once a month). I don't understand how to set the schedules, the backup retention, the full backup interval. I also need answers to the following questions, and I haven't been able to understand this from the documention. Do I need one delta backup with 2 schedules, or 2 backups with one schedule each ? I've noticed that full backup interval is per backup, whereas retention is per schedule. How do these two settings interact with multiple schedules? On what dates will the transfers be large ? How many full backups will be stored on the remote at any given time ? When will the merges happen? Thanks

    Do you get any errors that would help? You might only need to add the user correctly in /etc/sudoers

    @MichaelCropper, to answer your question, yes, I enabled networking during the installation process. This allowed me to SSH in following the subsequent reboot to run yum groupinstall "Workstation". VGA was enabled for me and then Video RAM was at 16MiB. @ben20ben brings up good advice with the XCP-ng tools, install it and life gets easier.

    The idea is to give the best visibility to your plugin Though I don't think we'll ship it directly to our customer because it's an advanced use case

    Nevermind. I don't know what I did, but eventually, the host was listed a halted and a Forget option was available. That did the trick.

    FWIW, this issue was likely due to using an outdated version of Node. The script is being updated to detect this scenario.

    Hard to tell. If it happens again, try immediately to compare XO behavior with other clients to see if we can tell where is the problem

    This is probably a snapshot created to be able to coalesce by the system (when the VM is up). Try to shutdown the VM, I'm pretty sure it will coalesce without needing another snapshot.

    Because I want to push users through a web portal interface which can obtain information from XO-Server for presentation back (ie: VM status, parameters, etc) whilst also allowing users to start/restart/shutdown VMs. We looked at XOA however it was too expensive and the free version has nag text messages which I don't want presented to users.

    They are two very different backup modes. Why not using delta + CR?
