    @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

    @olivierlambert - I'd also like to say that I'm a very recent homelab convert over to XCP-NG. I've been using VMWare for like... 15 years. I have a project at work that I use native Xen for, and have been really impressed with the security and control that we get out of it. I've been in the process of shifting over to XCP-NG over this Christmas break, and I've been really, really happy. There was a bit of a learning curve, but I'm very happy that I'm going to be getting an increase in functionality over my free ESXi instance. Really great work you're all doing!

    Yes you can do that, there's a tag on a replicated VM to avoid being replicated again.

    The issue is within pools: XCP-ng isn't meant to have pool members down (for various reasons), so the scenario is only limited to pools with one host only

    It's more work, but... you have to stop the VM and export them, delete the current SR (Local Storage), recreate SR (Local Storage) as local ext4 format import the VM back In this way you switch from LVM to ext4 and the space it needs will be small, not double the space

    @olivierlambert Yes, i will update and have a look if it changes the behaviour anyhow. "For the rest, it's hard to answer without digging more." That`t exactly was i was looking for: Any Information where i can dig deeper? I`m looking for logs or traces of errors or so. It is not that i just wan`t this particular problem to be solved In my limited understanding of interal processes i think somehow a backup process dies and xo-server does not report or recognize this. But shouldn`t it somehow?

    @olivierlambert Oh nice, hope it's not too cold over there. It's 9AM over here in Maryland and a bit nippy but not too cold. Nope, no host or pool logs available (both are empty). Then again, I cleared all the alerts from the dashboard earlier this morning, so not sure if that's what wiped all the logs. I'm not too worried, as this is a testing environment so I'm using this host to do a lot of learning.

    @Gheppy I am not an expert on the network part but I can help on the NBD part We added some info in this PR https://github.com/vatesfr/xen-orchestra/pull/6596, it should be merged in this form or another in master in a few days. It will give the user more info on the NBD usage and the cause (misconfiguration, or network error) Then if XO ( or the proxy) can't connect to the host through the NBD (for example with a network filtering/ routing), it will fall back to the reliable (but non parallelizable) api call Finally , the backup done with NBD or the legacy api call will produce exactly the same data so they are compatibles, but using the same target (as in the same directory , same remote and same VMs) for multiple job can lead to complex support tickets with interesting race conditions. I would advise to only use the same remote/directory only if the backups jobs does not concern the same VMs fbeauchamp opened this pull request in vatesfr/xen-orchestra closed feat(@xen-orchestra/backups): more information on nbd backups #6596

    @cdbessig that's strange Since S3 remote are only able to store blocks, the option is enforced on save ( without any uI) I tested locally and the options seems to be there. Can you show me a screenshot of the backup job configuration ?

    @trent234 Interesting, good to know. I do know that XCP-ng only officially supports 7 network interfaces, so not really surprised by that. It supports more VHDs though so feel like I shouldn't be seeing this error.
