    @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.

    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.

    @gduperrey said in XCP-ng Tools Storage contains VDIs I’m unable to Destroy: It seems that it is possible to clean old isos manually, via the command line, as explained in this forum post: https://xcp-ng.org/forum/post/15703 Wau!!! That actually works like charm! Thank you sooooo much!

    @andrewperry yes, we replicate TrueNAS to a "standby" TrueNAS using zpool / truenas replication. Our current policy is hourly. We then (plan) to do Incremental replication of all VM's to a standby TrueNAS over weekends giving a 3 possible methods for recovery. Currently we're running into a major drawback with VM's on TrueNAS over NFS (specifically VM's that rely on fast storage such as databases and recordings). We did not anticipate such a huge drop in performance having VHD files over NFS. We're reaching out to XCP to ask them to give us some advice as it could likely be in part due to customization we can make.

    @wildones It's good that the XCP hosts can reach each other, but that's not enough. XOA needs to reach all the hosts too. You may want to use an XO proxy to manage remote locations. Please read the XO proxy guide.

    In fact it's already possible In your replication job: Edit the schedule, check "Health check" box. Target the same SR than your VM are replicated too And voila!

    @stormi So I looked into the code of the ISOSR and there is a parameter for the version in the device-config. The parameter is vers but it can only be V1 or V3. And if it can't connect with V3, it will also try with V1.

    Hello @Andrew, thanks for your question! First off, I haven't tested Deno or Node with Xen-Orchestra yet. Changing the Node version can sometimes introduce bugs—some of which may be subtle. For that reason, I’d prefer not to venture into this unless it truly proves to be worth the effort. Secondly, in my experience, benchmarks don’t always translate into meaningful results in complex applications. That said, we are keeping an eye on alternative engines, both in terms of performance and the new features they offer. If we determine that the benefits are significant, we’d definitely consider migrating. Additionally, if any users want to experiment with Deno or Bun, they’re welcome to start dedicated threads on the forum to collaborate. We’d be happy to review and merge compatibility PRs as long as they don’t break Node and aren’t overly complex.

    @Danp So I had a problem with ldap, I read older article that mentioned doing this sudo npm install --global xo-server-auth-ldap which coincidently fixed ldap but that is when I noticed sync option were gone. This is just a POC and has noting running, so I will destroy and build new xoa. Thanks for help.

    @tuxpowered said in Rolling Pool Update - host took too long to restart: When the first note reboots (the master), I can see that the system is back up in 5-8 min. If I go in to XO > Settings > Servers and click the Enable/Disable status button to reconnect it pops right up. Again, does not resume migrating the other nodes. That is what I am seeing also, logged here https://xcp-ng.org/forum/topic/9683/rolling-pool-update-incomplete

    The easiest way to guarantee it is to depend on a local resource (local SR or ISO).

    If you proxy (or reverse proxy) any stuff, yes, you need to have a fixed address for the proxy.
