    @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.

    @aghering the [NOBAK] option only excludes the transfer process, it will still try to make a snapshot of the disks. There are many possible causes for your UNIMPLEMENTED IN SM BACKEND issue, the most likely causes are probably storage related. If it is not a critical VM, you can try to disconnect the second storage disk and try again. If that doesn't work you might have to forget the SR and try (you can reattach it again, just need to remember your sr-uuid. Also, your /var/log/SMlog might reveal something.

    Makes sense now that you mention it... Perhaps I should have realized that because obviously the backups only run on my primary XO instance. Thanks!

    Yes, backup jobs require attached schedules to be executed properly.

    Hi @tony yes I understand that, actually I made a post a while back spanning different aspects of the XOA and where I feel Center is more intuitive but as suggestion for XOA improvement if anyone cares to consider it. Regarding the adding of SR's to pools, I leave my suggestion here, have a selector for pool instead of host, it'd be more intuitive imho. Cheers all.

    Becouse xoa backup is painfully slow... it's good for CR but for full vm backup, let's say it's unsuitable... on my 1Gb lan, full vm backup (DR or Copy) from xcp1 to xcp2 I have about 10-15Mb/s. This is the topic I've asked many times on this forum. And guys from vProtect brag that the speed im much better on their soft due to CBT not vhd delta - which I'll check in a while.

    AFAIK, you have to do manual passthrough for USB so if you want to attach ethernet dongle to a VM, you plug it in the host and turn off the VM, passthrough the USB to the VM, start the VM, never do snapshot of this VM as it will fail.

    Hi, sorry for the delay! Please read xo-cli's documentation, you need to use JSON when you want to pass non-string values: xo-cli vm.set id=89517372-b45b-ca36-4c51-dd17c0e760c0 CPUs=json:3

    You can map root to a local user you created on the syno (so it's all on NFS server side configuration)

    Glad to hear it! There were probably an issue when updating the SDN controller's TLS certificate. The reload had solved it. Regards!
