    So if i set VMs to Best-effort or disabled for HA i get not enough memory. @pkgw Do you have Twinstore configured and/or HA enabled? If no I will continue my issues at the twinstore post. If i set to restart i get this.... host.setMaintenanceMode { "id": "35233210-4e37-4703-9bf6-9e8a9c24df9f", "maintenance": true } { "code": "HA_OPERATION_WOULD_BREAK_FAILOVER_PLAN", "params": [], "call": { "duration": 5, "method": "host.disable", "params": [ "* session id *", "OpaqueRef:d9bd976f-445c-8244-1b56-879f446efc12" ] }, "message": "HA_OPERATION_WOULD_BREAK_FAILOVER_PLAN()", "name": "XapiError", "stack": "XapiError: HA_OPERATION_WOULD_BREAK_FAILOVER_PLAN() at XapiError.wrap (file:///opt/xen-orchestra/packages/xen-api/_XapiError.mjs:16:12) at file:///opt/xen-orchestra/packages/xen-api/transports/json-rpc.mjs:38:21 at runNextTicks (node:internal/process/task_queues:65:5) at processImmediate (node:internal/timers:472:9)" }

    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/

    Hi @simonp. The problem is gone with commit 44e5b!!! Up-to-date XCP-NG host and XenOrchestra VM were restarted after updating XenOrchestra. I just initiated a full backup and all VMs - including my problematic machine - were backed up successfully without error. Awesome! I will wait with closing until the scheduled delta backup is completed successfully, too. Edit: Scheduled backup ran without issue. The problem seems to have been resolved! Thanks for all your work and assistance Regards, Marc

    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 said in Commands in Xen Orchestra Jobs no longer working: The best solution is to rely on XOA, you know I agree with @olivierlambert! Personally, I'm using XO from sources in my home lab environment -- nothing is "production" and I'm mostly having fun trying to give back to the open source community.

    @Danp - thank you. Yes, I did, but that was not helping in this case. Found the solution: Both machines are on a hostserver, which has NOT all networks. So the real reason must be a network problem, therefore a quite missleading error message After moving both VMs to the master of this pool (which is connected to the same network where the xoa resides), everything went fine. Same storage, same vhds.

    @indyj The file restore issue was due to installing XO on FreeBSD (fine for VM restores, not file extraction). I then installed XO on Ubuntu 20, and this worked for restoring files from Linux VMs but not Windows VMs. Then I installed on CentOS 8 and had the same problem as Ubuntu. I then installed on Fedora 34 and everthing works fine.

    Yes, it should be safe enough to try importing the backup, then starting the VM without network (ie VIFs) and see if it stays up for a few minutes. I think we could start by adding a manual feature and then see in a second step how we could automate it.

    Also, the user will be created only on first connection. Maybe you are thinking about the plugin in a way that's not how it behave.

    @olivierlambert many thanks for the very quick response, it is indeed XO from sources. I think the burst explanation makes sense. Also, thanks for you and your teams continued development and support with both XCP-NG and XO.

    What do you mean "how it works"? It's the same thing than before, just "isolated" from the rest, working in a... worker. And yes, the long run objective is the ability to run it as a service on the remote directly, reducing a lot the merge time (because latency is the worst enemy of merging).

    Backup does not work if one host in the pool is offline

    @olivierlambert said in Backup does not work if one host in the pool is offline: When you connect to a working, machine, yes it does But XAPI connection isn't persistent: it means, when the pool is disconnected, XO has no recollection whatsoever on who was the "real" master the last time it was connected. The only info we store is the IP address you entered in Settings/server. I agree, functionally speaking, it can be limiting in your case. A viable option would be to save all existing hosts IPs in the XO database, as fallback if we can't connect to the IP you entered. This is not a very common case, that's why it wasn't done before Looks like a good suggestion. Thanks. In my case I migrated everything from the poolmaster to the second host, then changed the second host to pool master, waited an hour and then shut down the old pool master (now just a pool member). XOA was online during the entire process and I had forgotten to check the server list.

    That's because the effort to change this will be taken into account in XO 6 Alternatively, you can indeed contribute, this will be very welcome!

    Hi ! We are experiencing these kind of problems because we activated Continous Replication and frequency was way too low. Now I want to eliminate all those files in the chain, can I do it manually from XCP-NG Center or XOA ? Thanks !!! [image: 1635327169557-c2aa1fb3-2ed2-41cf-b242-e2a23e6832e4-image.png]

    It can't be done by XO, because XO is using XAPI to make all calls (there's no XAPI command to rename a file on the SR, also XO isn't connected via SSH, so there's 0 change it was caused by XO). So it was done manually at some point (check your host bash history).
