    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

    @s-pam i'd say use them, always use the. Only a few KB of space and could be every handy. We have 3 servers in the pool so overlooked requirement for full pool recovery. (p.s we didn't fail, it's during DR testing it was flagged) we had the backups on already and if this had been a real issue, would have saved a lot of bacon!! turn it on ! (and check you can get it without a running XOA for quicker restore in full meltdown.)

    This section has nothing to do with XOA IP address, but useful to restrict some VMs to some IP address. I agree it's unclear. But as I said, for now, there's 0 GUI to configure the system per se. That's why I said it could be an addition sure, but there's nothing yet, so adding it will take some time or efforts, and it's not a priority as we speak (our backlog is already pretty big). But again, as an Open Source project, we are welcoming contributions!

    Questions: Placing a new VM in a suitable pool/How is a host chosen ?

    To pick a pool: it's up to you to decide, depending on available pool storage capacity, speed. Same for compute and network. It's very very specific to your own needs, there's no universal rules. Host selection for a VM: it's not decided by XO but by XAPI (except if you specifically ask to boot on a host). IIRC, it's a mix of load and memory available, but if you want to dig further, it should be written in the XAPI code somewhere

    @indyj FYI when I ran this test again it worked. this time: I ran it as a "Delta" backup. And then rescanned the removable media. I was then able to restore an individual file from the backup on USB media.

    @garrya Hi, it sounds like you've set up VLAN interfaces correctly on the XCP-ng side, but the switch they are connected to also needs to be aware of VLAN tags to pass them, or else it will only pass untagged traffic as you noticed. You'll need a smart/managed switch with VLAN capability to do so

    We are investigating an elegant solution called RunX. Basically, it might be able to transparently any standard "container stack" (Docker and/or k8s). See https://www.youtube.com/watch?v=9m95hojMtsU There's some work to adapt that to XAPI, but it might be doable. This means XCP-ng could be "container" native while having very good level of isolation with very small VMs (only few MiB overhead).

    5.79.3 / 5.81.0 All of my backups work (now), and speeds range between 5 MB/s to 20 MB/s. Most of my VM's are smaller (zstd helps a lot), though the largest archive is about 80 GB. Also, all of my backups are sequential -- I seem to remember a previous note where somebody had problems with concurrent uploads. My XOCE VM runs with 12 GB, which was the number that "just works" according to some of my earlier problems (and I haven't bothered to chase down or fine tune further).

    @olivierlambert having exactly the same issue as wcom939 reported. What did you mean by "Can you try with xe command to see if you have the same error?" ? Migrate using CLI? there are too many options:)

    @danp thank you, but in our case the 2nd remote is a hypervisor? I dont know how we should run the backup first then copy the VHD files to the the 2nd hypervisor as continuous replication also creates a VM? I am sure that if I can limit the amount of VM's that is exported once (it's currently 2) then the backups for the large VM should complete. Is there a setting available for this?

    Thanks both, agreed, in hindsight this should be configured on the VM itself as it could lead to unexpected issues (like maintenance and having VM's start by themselves) Thanks for the input

    Here is a good explanation: https://docs.citrix.com/en-us/xencenter/7-1/dmc-about.html Static can only be set while the VM is offline. Dynamic can be changed in live. When you'll live migrate a VM, it will be decreased to the dynamic min. So take care to use a value that's higher than your VM operating system minimum RAM usage.
