    @pkgw Planning an RPU as a whole is a nice idea in theory, but it's inherently designed to co-exist with normal pool management operations (you should still be able to migrate VMs between hosts B and C during it, or start new ones), we are not "pre-booking" memory and other resources for groups of VMs, otherwise it can quickly make the rest of the pool hard to manage while some VM migrations could still be far away. Regarding the narrower case - I'll note this down and see if we can improve things, thank you!

    Is a centralized XOA server "managing" two remote Proxy-fronted XCP clusters supported with the SDN Controller Plugin? We are looking to deploy an architecture similar to this blog post from 2022: https://xen-orchestra.com/blog/xo-proxy-a-concrete-guide/

    Thanks for checking. That's useful, even if it points away from where I was looking. Clocks within a second of each other means drift probably isn't your problem, and I'd guess the MST/UTC difference is just how dom0 displays it, though I'm not sure. What I keep coming back to is that your full backups fail while the delta jobs on the same hosts never do. That's the same split in https://github.com/vatesfr/xen-orchestra/issues/9181, where full backups hit BodyTimeoutError on VMs with big disks or a lot of free space and the deltas are fine. If your failing VMs look like that, your dates and the MST/UTC detail would do more good on that issue than buried in here. MajorP93 created this issue in vatesfr/xen-orchestra open Full backup fails on large VMs / VMs with lots of free disk space #9181

    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

    @Meth0d thanks for sharing your experience. Fortunately I was able to just hit "Convert to HVM" after my imported PV failed to reboot after upgrade from 20.04 to 22.04 - was all set to load a livecd etc too!

    @Danp I got around this by using Clonezilla to copy the disks of the 2 VMs I was having an issue with. This is very strange. The VMs booted and ran fine on the old host, I was able to clone them with Clonezilla to the new host where they also boot and run fine. There is something preventing the native tools from migrating these specific disks though.

    @DustinB As to why you're seeing "VM not found!" I don't know if that is a XO alert or something you added into the screenshot, I've never seen that so I can't speak to it. I didn't add the text, all I did was highlight it with the red surround. Just testing the backups again using the 'Delta' method and '[NOSNAP][NOBAK] Data drive' as the name of the second drive , feeling more hopeful about this one though. I'm starting to like XO the more I use it, would be good to move to this instead of switching between 2 different XCP-ng Center EXEs. depending on the XCP-ng version on the host so I really hope I can get this to work. The scheduled hourly snapshot while the guest is running looks a great feature, although I need to learn to walk with this first before I go that far

    @HamiltonWDS Thanks for the report. As it works with wget let use it! I'll switch from curl to wget in doc. In the meantime some colleagues will investigate more.

    Thank you very much for the clear explanation @HamiltonWDS ! This will be really helpful so we find a solution for that. We might default to IPv4 for a lot higher latency, and in the future maybe having closer location mirrors. Let me discuss this internally and schedule an action for that.

    Hi! Yes, we'll develop the hub in the future, we just lack the resource internally to prioritize this against the rest, but as we a growing fast, expect more things coming in here

    I have no idea for the legacy Linux tools, they are badly coded and you can get rid of them entirely We've been using them in prod since almost a year without any issue. 1.0 will come soon but it's already very stable and safe (it's written in Rust). Our goal is to get them in all Linux distro upstream ASAP.

    Posted this as I personally found this configuration quite involved, and the permissions earlier in the thread were insufficient to make it work when using AWS KMS for bucket encryption as well as the XO provided encryption secret.

    @nick-lloyd So looked at the network ports on the host it is going to. They show disconnected due to they are in a bond lacp so the 2 network ports show as disconnected but the bond shows as connected. Also have other VMs running on the receiving host so know the bond is working.
