    Hi @dvdwx, RBAC is available only at the REST API level, not through the XO6 UI. UI compatibility with RBAC is currently under development. For the topology, this is something that has been here for a long time, so I may be wrong since I don't have the full history. However, if I look at the code, creating the topology selector requires knowing how many CPUs are available in the pool. Since a self-service user doesn't have visibility into the pool, they can't access this kind of information.

    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/

    @pedro_udifar Hi, This is a b2 side error. It could be just a transient error, did you try to restart the backup?

    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

    XOA shows hundreds of client connections

    I ran into something VERY similar with XCP-ng and\or XOA a while back - ended up with close to 200 new "clients" showing up on my Meraki gear. They weren't even "connected" long enough to register as IP clients, only MAC clients (ARP, possibly). I didn't think much about it at the time, as both the MAC addresses and hardware information didn't seem to be tied to any actual device by some manufacturer. I may be able to pull those out from my client history... EDIT: Here is a small section of that list: [image: 1556589256050-fc439a0c96cb13a0b2b11b3bd80ff3be.png]

    To get assistance on XOA, since you have support, it's better to go with our support ticket system. This way, you can be sure to have an answer with direct developer access in a guaranteed amount of time. Please open a ticket here: https://support.vates.fr/#/tickets XOA isn't dealing on what's inside on the VM: it's an hypervisor-level agentless backup solution. As soon you create the ticket, we'll take a more in-depth look about details (what kind of backup are you using? Delta or full etc.) and also if there anything special we could do at our level.

    I don't know what's the /xen path? Install via this docker isn't the official/documented way, so it's hard to assist. Please try to build it according the doc and double check if reverse work as documented too. Otherwise, it's an issue of the Docker you use with our doc, so you'll better time to create an issue on the 3rd party "installer".

    It depends where you decided to install it (basically where you cloned to repo). Also remove the redis database if it's only used for XO.

    If you didn't, I strongly suggest that you watch the live YT webinar I did on XO backups. IIRC, there is a part talking about smart backup. https://www.youtube.com/watch?v=FfUqIwT8KzI

    You have a problem on your XCP-ng, this is not related to a XO issue. It's stuck doing a snapshot, which is really a basic operation that shouldn't fail at all. Double check your SMlog on the host.

    It looks like I can remove the remotes and set them up again, and configure the backup jobs to address the new share. That's okay, there are not too many.

    You need one XOA, connected to both pools. It will stream the VM content (delta) from the source to the destination. You don't need any directly link between your SR in both DCs. You DCs can be isolated with just one XOA connected to both, and it will work.

    No XCP-ng/XenServer workaround, it's a "built-in"/by design limitation (it's considered as "stalled"). So your goal would be to avoid these extremely long tasks (ie: to finish before the task is destroyed)

    You'll end up with a chain, yes (so every read will need to make "hops" on each member of the chain). Longer the chain, slower the operation. But it shouldn't be too catastrophic either (for a heavily IOPS loaded VM, you'll notice the difference, but not in other less IOPS hungry scenarios)

    Sure, thanks. I'm using xoa and desktop app simultaneously. I hope that the desktop app will be available for long time.

    No, because those logs are useful in case of problem (to find a potential bug). However, they are garbage collected automatically (the oldest ones) after a while.

    All I can tell is that's not an usual issue. Never heard of problem of this kind before… So yeah, there is something weird. Could be related to NFS permissions maybe, or something between XCP-ng and your NFS host. It's not XCP-ng code directly, because otherwise everyone else using NFS will endure the same problems. So it's more a "combo" between XCP-ng and your NFS within your infrastructure. Please read the wiki on where to check logs (especially SMlog) to spot potential hints on where's the issue.

    @S-Pam Having a VIF for management and one for storage-traffic is a good solution, we do it that way to avoid crippling management during backups.
