    @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.

    Hi @pierrebrunet With commit c74a8 the problem is still present but the transfer was completed again. Unfortunately my installation does not recognize the "xen-bugtool" command. And both log files are not present. Is this something that needs enabling after install of XCP-NG? Unfortunately and unnoticed my syslog-server did not receive any messages from XCP-NG in the last 30 days. Other inputs work **Edit: I have deleted and re-added the syslog-server with port and now logs are being send to Graylog.** Thanks for your assistance y'all. Regards, Marc

    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.

    Of real RAM usage? Eg with htop, take care of the cache too, because even if the cache is used doesn't mean it's really important. Maybe 8GiB is enough for example.

    Nothing like that could happen. If your orphaned VDI is in use, it will error out with "VDI in use".

    @olivierlambert I can do it pretty easily, but there may be a good reason for XAPI to throw this error instead.

    @shinuza The version inside the Debian image and the version on GitHub may be different. It is likely that there will be more recent versions on GitHub. Just don't select a version and the latest version from the Debian repository will be installed. const k8sInstall = k8sVersion !== undefined ? `apt-get install -y kubelet=${k8sVersion} kubeadm=${k8sVersion} kubectl=${k8sVersion}` : "apt-get install -y kubelet kubeadm kubectl";

    @Danp I agree with you here, but they also mentioned a "different newly created VM and attempted to install Windows 10 with two hard drives" and they only saw one disk, so was seeing if maybe the issue is related and there is something setup wrong. All disks should be visible to the Windows installer.

    Yeah I'd check BIOS settings like @olivierlambert mentioned here. But also, you mention pass through, this isn't pass through this is vGPU which is different (and only supported by some GPUs in specific), which allows you to have a single GPU that can run multiple VMs. If you want passthrough you'll need to follow the docs here https://docs.xcp-ng.org/compute/ This will let you pass through the entire card, make sure to passthrough all devices that are part of the card (so HD audio and stuff too, everything that is under the same PCI address). I've done this with a few GPUs and it works great.

    I can't say for sure as I haven't tested it, but it may "just work" if you swap them out, a lot of systems do support swapping SFP modules without extra work being done. But again, never tested it at all myself.
