    @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.

    I get this error with each metadata backup run, but every time it fail on different pool. Only 1 failed pool at once. [image: 1782727042952-aa7af767-9150-4e99-a483-5d02524678bb-image.jpeg]

    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

    Sounds doable, but it's another feature in the backlog We really need to move forward with XO 6. However, can you: check if there isn't already something in XO Github repo on that topic if not, please create it This way, we are sure it won't disappear

    What do you mean by moving? Moving the disk or just the VM memory?

    Okay, cool down and let me explain a bit That's because those templates are not part of Xen Orchestra software itself, because those VM templates are things we build and assemble on our part, then upload to our own servers, hosted for people registered with the virtual appliance (XOA). So using XO from the sources is not losing any XO features because XOA hub templates aren't part of it This is extra stuff outside XO scope, that we give for free for our XOA users (yes, XOA Free users). So we do not get any money for this. It's just operating systems pre-configured with Cloudinit installed (or sometimes not). Again, it's not part of XO itself, and nothing prevent you to build your own templates, ready with Cloudinit. I hope it's more clear now.

    @olivierlambert said in Warnings & errors in journalctl: Do you have multiple XOs accessing the same remote? There's only one backup job running from my XO VM. There is an active instance of XOA, but it is just used for testing and is sitting idle.

    You need to restart the service as root/sudoer, eg sudo systemctl restart xoa-updater. Note that you can have XOA support with our ticket system, even on XOA Free If you want someone at Vates dedicated to your issue, please create a ticket!
