    @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. Release notes and migration guide: https://github.com/vatesfr/xenorchestra-csi-driver/releases/tag/v0.4.0

    @florent Limiting concurrency did not fix my S3 backup problem, but it's working again after updating the build. So I guess it's resolved.

    You should probably be able to fix this issue by installing the ntfs-3g package. As you mentioned you're running it on a Synology, you can do that in DSM by opening Docker -> Container -> Select your container -> Details -> Terminal and enter the below in the console. apk update apk add ntfs-3g Let us know if it helped.

    @olivierlambert Well, for now, I'm mostly playing around with this tech to teach myself about it, gaining experience and coming up with ideas. Maybe someday I'll be able to return some profit with the business I'm building / trying to figure out (hosting game servers). Then I'll sign up for some Pro support - and maybe then we can work on the concept of HA XO I understand what you're saying. I think I can come up with a good enough way of achieving the HA I'm looking for. Anyway, thanks for takning the time to respond. I understand your schedule is busy.

    If you use XOA, I would strongly suggest to open a support ticket. This way, we can investigate properly on your XOA and see what's going on.

    Weird Issue with NFS and Synology Hyper Backup

    It's important to understand the components you are using, especially on a software that you use without support/training In short: SR: a Storage Repository is access by your host/dom0/XCP-ng, and will be used to store ISOs and/or VM disks. It's running on a relatively old CentOS release (7.x), and will mount with some specific settings BR/remote: a Backup Repository where Xen Orchestra will send the backup of your VMs. Usually, Xen Orchestra runs (in XOA) inside a Debian 11 VM, with default NFS mount options (default: ie from the operating system point of view). It's hard to tell exactly the issue since you are likely using XO from the sources, so a XO that you choose to install on a system where we (aka "XO devs") have precisely 0 control on. Plus the NFS configuration part is also out our scope because it's not running inside our infrastructure too. That's a lot of moving pieces, that's why it's important to understand what you do so we can assist here the most efficient way we can

    There’s usually little to no reasons to expose any mgmt systems to internet in actual production environments. Especially if it’s strictly for internal mgmt purposes. XO is no exception. Not because the system would be unsecure, but you simply want to make any attack surface as small as possible. It’s just a best a practice.

    @ronivay Ok. In between jobs I did a new VM install of debian 11 and on it the XO community version. Version numbers now: xo-server 5.100.1 xo-web 5.101.1 I seem to have everything working again. Thanks for the help and tip. Now it seems really solved. If I come across anything else, which I don't think I will, I will report back. Greetings and thanks, Jan
