    @florent I rebuilt my XCP hosting environment (everything is faster and bigger stuffed into one rack).... and this issue is now worse. The main changes to this new setup are 2x40Gb networking, faster NFS NVMe NAS, faster pool servers, more memory, much faster CR destination machine with ZFS. Running XCP 8.3 (March 2026 updates) and XO (master a2e33). Replication is leaving many attached to control domain every day with NBD connection set to 2. Changing it to 1 seems to resolve the issue (no more stuck to control domain).

    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

    @bberndt said in Create job to migrate several VMs: Tring to create a job, to schedule the migration of several VMs to another host. At the bottom, there are a couple things I don't know. There are two check boxes here for each of these: mapVdisSrs mapVifsNetworks They don't seem to do anything. What are these? Also, what goes in the box Migration Network. The name storage1, or network1 don't work. thanks. Ah! the UUID of the storage Migration network on the destination is what I need, apparently.

    Check host logs to understand why. Maybe those VHD were attached to the control domain or something like that.

    @akurzawa xo-server is not explicitly multi-processed, but it uses async IO calls in Node which should lead to multi-threaded operations. Anyway, we are currently working on reimplementing backups for the proxy and it will eventually lead to using multiple processes. These changes will at the end be merged back to xo-server as well.

    If you create two separated jobs. One for the CR and one for the Rolling snapshot they will not interfere.

    OK the tasks (it been 8 hours since I've checked) are gone, but the VHDs localted on backup server's localstorage remains. QUESTION: How to delete VHDs that are not realted to any vm? I think it will not be deleted automatically. EG. For example - I've deleted "Atlas" VM, but big atlas VHD remains on BackupHost's local storage: [image: 1581667660068-666ed028-c8e0-4ae7-86f3-1a307f7eee76-image.png]

    Hi, It's possible to do it using the UI, simply create a schedule with 7 as Backup retention and 2 as Replication retention. [image: 1581581696403-fd938a54-8730-4bcf-85c3-7caf2018ac52-image.png]

    Because there's a ton of dependencies, and we try to decouple things, this work takes time. We should be able to run on a more recent version of Node soon, and when it will be the case, our doc will be updated accordingly. That's exactly why we can't support 3rd party installers. Our doc might change and during the interval, if the 3rd party installer isn't following, then it will break.

    OK, seems I wasn't trying hard enough. I was trying to mount the tools under the iso list, but when I look further down the list to xc-ng Tools it turns out I can mount the tools from there as long as I do it manually (mount /dev/sr0 /media/blahblah). Installed now, all good.

    There's no tool to "merge" old forum or fetch old message. So for few months we'll still have old XO forum then it will be automatically redirected to the XO category here.

    It's just a missing info in a config file of the appliance. Not a big deal, just surprising to see that now, despite the fact it was there before.

    Hi, So I tried using the NFS target remotes but the speed of transfer was very poor even though the connection from XO to the NFS server is over 10Gbe. XO is on the same XCP-ng host as the VMs being backed up. This XCP-ng server is connected to the NFS mount over 10Gbe network: [image: 1581002643082-56cc5a0a-e633-443b-9a50-6575ef5cddaf-image.png] Here is the NFS Remotes setting in XO to the backup server (FreeNAS) at IP 10.10.2.3:[image: 1581002745614-046fcdaa-8788-4d69-aa00-c1620a0afb46-image.png] The backup logs show extremely low transfer speed: [image: 1581001993532-b51d304d-2fb6-472f-8eb9-0dbec967d49c-image.png]

    @olivierlambert Thanks again for the reply. I’m looking into it more. I think I need to add the storage directly to the VM running XO. I was trying to use a drive connected to a drive on my local network. Though it says it can talk to the drive, it does not reach it. I’m trying now to add an NFS to the XO server.

    You can avoid transferring some disk data with the [NOBAK] title in the VM disk. However, a VM snapshot isn't capable of ignoring a disk. This would require a change either in the way we do backup in XO (not using VM.snapshot, but VDI.snapshot instead) or modify XCP-ng API to support VM.snapshot with excluded disk. The first option will make quiesce snapshots impossible. The other one is a bit more complicated to realize, but not impossible. The issue already exists in our bug tracker: https://github.com/vatesfr/xen-orchestra/issues/2560 julien-f created this issue in vatesfr/xen-orchestra closed [Full backups] Supports `[NOBAK]` #2560
