    @florent Thanks for your reply! We have started to migrate thousands of VMs, so disk transfer speed is important for us.. We will also do our detailed tests soon with different threads setting and publish it here. I think threads=1 is a good and logical default, but not efficient. Others might complain if you set it to a higher value. Configuration option would be a real good solution.

    Hello I'm pulling stats for all VMs to understand CPU usage. We're a bit behind the curve in terms of XO versions, but these questions hopefully are still relevant. If using a granularity of days, the interval is set to 86400 (understandably) but the endTimestamp varies. Running this on June 9th @ ~1740 we get timestamps for both Mon Jun 8 01:00:00 AM BST 2026 and Tues Jun 9 01:00:00 AM BST 2026. Does this average across the day? Why is the timestamp 0100? Why would there be different timestamps between VMs (all are running) and does that mean that the figures are misaligned in the results? These are retrieved via curl and a bash script, a bit hacky, but for clarity the request is: ++ curl -X GET -s -H accept:application/json -b authenticationToken=[[REDACTED]] -o [[REDACTED]] 'https://[[REDACTED]]/rest/v0/vms/[[REDACTED]]/stats?granularity=days' Really keen to know if we can control the start and endtime, as well as provide a manual interval, as well as the aggregation strategy (min, max, average). Are any of these possible? Lastly, is cpuUsage the percentage as per the dashboard, but averaged over all CPUs? Thanks so much in advance. James

    The Kubernetes CSI driver for Xen Orchestra just hit v0.4.0, and we want it on more real clusters before it reaches a stable release candidate. If you run Kubernetes on XCP-ng VMs, this is a good time to give it a proper workout. What's new in v0.4.0: Local-storage support Automatic pool-discovery fallback Kubernetes metadata now lives in Xen Orchestra VDI tags instead of the deprecated other_config. That change also drops the old requirement for Xen Orchestra 6.4 or newer, so the driver runs on more deployments now. ️ Read this before you upgrade. v0.4.0 is a breaking change. The Kubernetes metadata moved from other_config to VDI tags, so you must migrate before upgrading from v0.3.0. Do not upgrade in place: follow the v0.3.0 to v0.4.0 migration guide in the release notes, then move to v0.4.0. What helps us most is hearing how it behaves on your own setup: what works, what breaks, which storage backend you use, and which flavour of Kubernetes you run (k3s, full k8s, or something else). Edge cases on real clusters are the ones we don't see in our own testing. Where to report: start right here in this thread. It keeps everything visible to the community and lets others on the same setup jump in. If something turns out to be a reproducible bug, we'll move it to a GitHub issue on the repo so the team can track it to a fix. Release notes and migration guide: https://github.com/vatesfr/xenorchestra-csi-driver/releases/tag/v0.4.0

    XO 5.72 Storage Maintenance

    @geoffbland Hi, thanks for the reply... That's what I wound up doing, installing XO from source on a Raspberry PI that I had. I used it to restore my XO image from backup, once I did that I had to restore all of my guests (12 of them total). I could never figure out how to get my SR out of maintenance mode, so I wound up creating a new SR and restored each backup to the new SR. All back to normal after restoring the backup. Thank god XO backup works so well! I learned the hard way that I need to move my XO disks to local storage before I enter maintenance mode for my iSCSI SR... Oh well, lesson learned!

    @pdonias said in Netbox Plugin Enhancements: Why do you have those interfaces? Could you explain your use case and why they're not visible in XO? Sorry, you're right, hosts are not synced for a simple reason: there is no such thing as host types in Netbox (or did we miss something?). So we only group VMs by pools (clusters) and that's it. Those interfaces are for example wireguard interfaces or any other virtual interfaces. Obv they are not in xo because they are virtual, but in netbox they are needed because I deploy all my wireguard stuff with them. The host thing already was answered, there are devices which you then can link to Pools. KR Peter

    @julien-f It is likely a broken xva. I did interrupt those as they were exporting, however I was a bit confused as to why it was checked by a different backup task. In other words this screen clip is from a delta backup, not a xva export. I was more expecting it to show up on the XVA export backup task.

    Backup automatic retry

    @florent @olivierlambert Looking at failed S3 backup problems the retry should be easy. Currently on the job report there is a button to restart all failed VM backups in that job. Can you just add an option for automatic restart failed VM backups after job completion. It can even be a separate job (just as clicking the button is). It would just "click" the restart failed VMs button once (or a setting) after a few minutes (or a setting). Or it could start the new job as pending or delayed and start after a few minutes allowing for time to cancel it.

    @olivierlambert i have created config.httpInactivityTimeout.toml in /opt/xen-orchestra/packages/xo-server with the content from above. Not sure how i can check if thats actually set. BTW: this is not a CR Backup Problem, i also dont see Tasks running for my "normal" Backup Job. I cant check "how far" the actual Backup runs and if that differs. https://github.com/vatesfr/xen-orchestra/pull/6315 rajaa212 opened this pull request in vatesfr/xen-orchestra closed fix(xo-web/tasks): tasks with no bound objects not displayed #6315

    Backup a VM with all its snapshots?

    @Zevgeny For a few snapshots it's fine - the issue comes when you have large numbers. Most of my first-hand experience with this specific issue comes from Hyper-V but the logic applies here. This is from VMware but the concept is the same and has some good reading on snapshots in general. Running a virtual machine on a snapshot for extended periods of time can cause instability and data loss. https://kb.vmware.com/s/article/1015180 The underlying issue stems from the nature of snapshots. With none you have a single VHD containing all of the data for the VM, once you take a snapshot a new delta VHD is created with all new data written going forward from the time of the snapshot. So, in order to have a complete VM you have the original VHD + the delta VHD. This is fine in smaller numbers, but once you start having 10, 15, 20+ snapshots, every one of those represents an additional VHD in the chain. This results in performance degradation because you're reading from multiple potential files as only new data is written to the deltas. This is actually from XO's blog: https://xen-orchestra.com/blog/xenserver-coalesce-detection-in-xen-orchestra/

    Happy to do baby steps If / when you guys add some kind of "register" option to get a count on things I'd add my instance(s), as long as it doesn't break the existing install / upgrade scripts at least! Generally I have no issues with just clicking it away since I'm the only one that sees it. If it were a viable option sometime in the future, those would be my ideal "features". I've really enjoyed using XO coming from ESXi / vCenter at work and formerly running my home lab. Your vision of support is similar to Nutanix's which is partially why we went their route for our server overhaul and I think it's excellent. I'm hoping by the time we're due for a refresh the hyper-converged offering is fleshed out and production ready. Though I would miss my integrated firmware upgrades.

    @olivierlambert Yes this is really great. I have a windows box where I experiment with bluetooth a bit and having backup on this machine at least once a week or so feels very good I think I think it also makes sense that a machine that needs to be taken down in order to make backup also probably will need another backup schedule.

    @ronivay very good point thank you! I guess hourly is excessive when snapshots are available. Will just schedule hourly snapshots instead as the main point is to be able to revert in the event of a breaking change.

    @julien-f Restore showed that there were backups even when it said it failed.... I did not test one, sorry. I deleted the snapshots and old backup data which forced a full backup to S3 and XO was happy. A delta backup after that was also successful.

    @MilitaryNerd Have you restarted the host since removing this bond? It's reporting that bond0 is still attached to an OVS bridge, so it may need a reboot. You can also ensure the bond is really gone by running xe bond-list, it should return nothing. You could also still have the bond PIF existing or other networks using the old bond, check that you don't have any PIFs with device ( RO): bond0 listed when running xe pif-list
