    @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 said in Detached Backups: You can do that already if you like (combined rolling snap and delta backup). But what's the point? Oh, wow. You can combine backup methods in the same job (as long as they are compatible methods (i.e. Delta and CR). This is cool. I currently have separate jobs for my deltas and CRs. I'll need to make time to make the changes, but this will simply things greatly. I'll even throw in a few extra snapshots to retain. So, yea, this is pretty much what I was thinking of. I didn't realize it was there. Why would I need this? Well, when my WSUS installed the Xen drivers on all my Windows VMs, I went a day before realizing what happened. A snapshot would have been sufficient, if I had one from the day before. Instead, I restored the backup which broke the chain. @olivierlambert said in Detached Backups: edit: about your previous question, restoring without breaking the chain. That might be possible. In theory, after restore, we should take a snapshot before booting the backup and then re-link the restored VM to the backup folders. It's doable (renaming some folders correctly) but I'm not sure this will be very useful. I'll look into this when I get some time. Thanks.

    Hi, If you want to change the background color, you need to update the $side-menu-bg: #044b7f; in ~/xen-orchestra/packages/xo-web/src/index.scss . Best regards.

    That's precisely the difference: a delta backup is stored in a remote, a CR is stored in an SR.

    Not a huge deal currently, but if I had a number of VDI's spread out, it could exeed any single available space which means I cant restore at all... Can this be done in an alternative way via CLI?

    What does your cloud config logs show on the guest OS after boot? Can you see if it has made any attempt to inject the config? Only thing I can think of is that your cloud config might be wrong thus the cloud init service is refusing it. Have you tried to use an ubuntu image? I used official images of both debian 10 and ubuntu 18.04 and worked fine once I got rid of the pre-populated network config or inserted a real network config. I spent too long trying to figure out what was going on so let me know if there's anything else you need to know, it's super frustrating.

    Question: Delta backup retention vs. full backup interval

    @Vinylrider your understanding is correct, delta retention is just how many deltas to keep before merging the oldest delta with the full. Full backup interval is the time between each new full back up for use in case of corrupted back up. To answer your question, yes it is recommended to have more than 1 full back up to fall back to in the event of corruption espcially of delta backups since delta backups rely on previous deltas meaning if one of your delta is corrupted, you'll loose all data from that point onward until another full backup is made, or worse your full backup could be corrupted (more likely because of the file size) then you loose the whole chain. And if your corrupted delta is merged with the full, you'll probably have a corrupted chain aswell.
