    @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.

    Adding Server to Pool Hangs/Fails

    @sgroel Curious. Are all the NICs the same on the existing pool hosts as well as the new host you add? Do all hosts have the same hotfix levels and the same overall hardware architecture? Seems odd as I ran servers this way for years. Maybe also look at the network switches to make sure they are all configured correctly. Finally, any clues in the /var/log files?

    @Darkbeldin I checked the xensource.log on the server and found the error message "failed with exception Server_error(INVALID_DEVICE, [ autodetect ])" during export, similar to the post here: https://xcp-ng.org/forum/topic/4319/invalid_device-autodetect-during-backup I checked the XO dashboard health and found 256 "Pool Metadata Backup" VDIs attached to Control Domain. Not sure how or why the "Pool Metadata Backup" got stuck attached to Control Domain but I guess it has reached the 256 limit. I "Forget" all of them and full backup seems to be working now. For the record, it wasn't anything to do with snapshots. The VM was OFF so I guess it doesn't need to take a snapshot before transfer hence the log doesn't mention snapshot.

    @bullerwins It's a wonderful feature, you can have customized filters for VM, storage, Templates, and Pools. Combine that with using lots of tags and it makes larger deployments very manageable.

    Cloud configs allow {{name}}% substitutions. From my perspective (as a user), for how {{name}} is used in my cloud configs something like {{address}} would be identical. What is the intended use case for the IPAM functionality in XOA if it can't be used like this? Real question, not trolling

    Also note the text at the top of your screenshot: to continue you need to select a boot device. There might be a way in that menu (or partition creation submenu) to mark that created partition as bootable, or maybe you just need to highlight/select the partition under "used devices" before hitting "done"

    @encryptblockr hope to try the same with their even smaller "CORE" images. There is not an .OVA download but .xz downloads that when expanded have .img . https://cdimage.ubuntu.com/ubuntu-core/22/stable/current/ubuntu-core-22-amd64.img.xz and https://cdimage.ubuntu.com/ubuntu-core/22/stable/current/ubuntu-core-22-amd64+intel-iot.img.xz cloud-init seems to require experimentation and these small images boot quickly for me. Are you then following Fohdeesha's instructions?
