    @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.

    VM migration stuck at 100%

    I ended up restarting the toolstack, which caused all of the migrating VMs to be in an error state, as they were halted but the system thought they should be running. I couldn't perform any actions on them. VM_BAD_POWER_STATE(OpaqueRef:f1f14751-cbc8-4a86-b98f-9e980b2b0d00, Running, Halted) After restarting the toolstack on all the hosts in the pool, they finally showed up as powered off and I was able to get them back up and could migrate them. Is there anywhere I can look to see why the migration got right to the doorstep and stopped?

    @hoberion This should be fixed since XO 5.48 (xo-web 5.61.1) @hoberion said in notifications: @pdonias said in notifications: Hi @hoberion, what version are you using? xo-server 5.60.0 xo-server 5.60.0 was shipped with XO 5.47. Could you update your XOA and confirm that it fixes it? It should happen once more after the update and then it shouldn't happen any more.

    No, because SR ISO is read only in XCP-ng (so we can't ask XCP-ng to import a VDI there) sadly. There's 2 options: Modify XAPI code to allow VDI upload (and not mount ISO SR in read only). Then in Xen Orchestra, it would be trivial. Modify Xen Orchestra to mount the SR itself to upload it there. It's a bit complicated but doable.

    Personally, I wouldn't touch anything regarding XVA generation, it's deep into XAPI code. Rely on delta backup in general, it's better.

    @RKENS Good question, during the replication, a new VM is created with the same settings as the original one, and this at every run. Therefore that's perfectly normal that this property reappears. I don't see how that's a problem because, as you said it yourself, the start operation is disabled by the replication job. I think it makes sense that the auto start is set like on the original VM so you can simply start the replication when necessary without having to think about enabling it.

    I answered my own question. For continuous replication, delta's are automatic. I was thrown by a backup job where I mistakenly selected disaster recovery instead of continuous replication and didn't realize it.

    You do need a lot of virtual memory for build but you can get by with 2GB ram + 4 GB swap if you tell nodejs to limit it self, by setting export NODE_OPTIONS='--max-old-space-size=3072' before starting the build process
