    @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.

    @olivierlambert There are lots of messages about: unable to parse XAPI datetime "2023-03-01T12:41:47.000Z" But nothing about the upgrade process. I was able to upgrade hosts 2+3 without any problem - but not automatically

    @olivierlambert to not create new topic, small continue here. timeout option still ignored. probably because of network problems i got backup error and job hangs every day. doesn't matter why it happens, but job will never get terminated by timeout. 21h job with 7h timeout. https://pastebin.com/U5HgKEzM just 1 Gb. [image: 1677660778089-1c80c5b5-248f-4506-a351-5bca47ee4f8c-image.png] [image: 1677660855604-7458ace9-3e08-4537-a7da-2d304033995e-image.png] i setup scheduled task to reboot xo once a day, to close this endless tasks.

    @cookie-eater2000 make sure your Xen Orchestra also has a connection on the 10GB network (IP address on the xo vm)

    @olivierlambert I do not understand wha t you mean by "You probably need to transform the disk in a "regular" and not snapshot". Not sure on how to do that, please provide the steps or if you have SOP ready, please point me to the SOP document.

    I don't see any obvious settting, and XCP-ng won't interfere with a guest OS installation, so the root cause for this missing GRUB_ENABLE_BLSCFG=true must be somewhere in the installation process, triggered by I-don't-know-what when being installed in an XCP-ng guest.

    @magicker If you are able to deploy an official XOA and reproduce the problem in it, I'll be able to investigate once you open a support tunnel: https://xen-orchestra.com/docs/xoa.html#support-tunnel

    Hi, The best practice is just to connect XOA to the master. You are thinking as if this situation will happen on regular basis, but it won't, and if it does you have a bigger problem than an XOA disconnection. If you have a backup job with email reporting, you'll be notified if XOA lost connection to the pool. There's nothing specific to do.

    Yes, you need to get them flat in the folder, it doesn't crawl subfolders.

    Very likely indeed. We hope to recreate the XO website from scratch at some point, but it doesn't mean we'll let this slip Thanks a lot for the report, adding @Marc-pezin in the loop
