    I've got my OPNsense (FreeBSD) router running in a VM on XCP, and it does have the xe-guest-utilities installed. I'm trying to figure out an issue on one of the interfaces, and I noticed a weird discrepancy in XO with this VM. The MAC addresses and such for the interfaces being used by the VM are all off. It seems that VIF #0 is the only one coming up correctly. Unfortunately, I don't think the FreeBSD or OPNsense teams have a maintainer for the xe-guest-utilities package, and so what they distribute is showing as 6.2.1-76888 in XO. [image: 1773276971518-xoa_guest_discrepancies.png] I don't know if this is what is causing my network issue, but I thought it strange.

    Yesterday, I installed the patches on my three hosts and rebooted them, directly followed by updating XO on my Debian machine to the latest (2cd5b at that time). Since then, both the evening-replication (21:00) of my Deb12-XO host failed, as well as the morning-replication (09:00). This one has never failed before and is (was) being replicated to another host on the same network. The mail-report says: Debian 12 XO self-install Pool id: 4cc74549-71c3-31d5-f204-7106e90acd1e UUID: 30829107-2a1b-6b20-a08a-f2c1e612b2ee Start time: Friday, March 13th 2026, 9:00:01 am End time: Friday, March 13th 2026, 9:00:28 am Duration: a few seconds Error: _removeUnusedSnapshots don't handle vdi related to multiple VMs Deb12-XO - Deb12-XO - (20260312T200004Z) and [XO Backup Deb12-XO] Deb12-XO As my XO-installation is outdated, I will update again and let it retry the replication without any other changes. Also, this is probably nothing else than an annoying incorrect error message from microsoft: [image: 1773425734846-74296a2e-ef15-4e92-afc1-82a851a57462-image.jpeg] What I did: followed the link in "About" to the current commit, went back to main, and clicked the link to all commits to see what I've missed (4 commits after I update XO)

    After updating to XCP-ng 8.3 (March 2026), IPMI / iDRAC information fails in both XO5 stable and XO6 stable (built from sources). It is thrown a XENAPI_PLUGIN_FAILURE log line for failure of the "ipmitool lan print" which works fine on the (DELL) node(s). These are old PowerEdge R430 and R810 with iDRAC versions 6 and 8 and worked well before the upgrade, so I guess tihis may be due to a XAPI command failing. Worth mentioning for this nice-to have feature.

    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

    @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

    This may be related to https://github.com/xcp-ng/xcp/issues/282 My guess is that the tools ISO was mounted into the XO VM, then updates were applied to the host that contained an update of the tools ISO, which led to the XO VM having an non-existing tools ISO still mounted. I have made a change in 8.1 to avoid that (eject all tools ISOs after updating the ISO, not just from shutdown VMs), and testing will tell us whether that's a good solution. To solve the situation, you usually just need to eject the ISO with xe vm-cd-eject, not xe vm-cd-remove, as @tuxen said. If you had a snapshot of the VM before removing the CD drive, I think restoring it should bring the CD drive back and then you can eject the CD with xe vm-cd-eject... Unless restoring the snapshot also fails. Else as tuxen said you need to recreate a CD/DVD device and attach it to the VM. iw0der created this issue in xcp-ng/xcp closed This operation cannot be performed because the specified virtual disk could not be found #282
