Thanks a lot for the feedback, @christopher-petzel !

@Dan Hello,

I can't answer from memory, we'll take a look at this and come back to you

Thanks for the report, I guess it could be considered a bug since even it's one of the other, it's not the expected behaviour to have the mode change between runs.

We are fully aware of Broadcom's decision to stop providing the VDDK library to the cloud community or to reserve its download to some authorized partners and customers. As much as we regret this decision, we have to respect it.

Because it impacts users who need to make backups, we are evaluating alternative options to address this situation. We will provide further guidance as this evaluation progresses but can't share more information for now.

Hello there,
Thanks a lot for raising the question and offering ideas to move forward @caps ! I would like to say that I really like the AI crafted screenshot provided 🤩

But, to be clear, the status as of today regarding Docker or other containers integration in XO/XCP-ng is that there is an item in the DevOps Tools team roadmap. The item is just to look and define what could be done (example update xscontainer, do something totally new, ...). Unfortunately this spike has a low priority and is not yet scheduled.

That being said, there is an active project, which is close to what you're asking. It's about a better integration of Kubernetes, including, cluster update, adding nodes, etc. More on this should come in the next months! ️

Also note that I am chatting with different people and teams in Vates about this thread and the Docker integration topic to see if we could do something.

Also last thing is that, the community is always welcome to build on top of our open source softwares. I am pretty sure that if someone would contribute a Xen Orchestra plugin to integrate Docker we would welcome this, and we could give tips and guidance. Like @teddyastie said, I'm not sure having Docker, Podman, related features in the guest agent would be something our colleagues would merge. But maybe the docker daemon socket could be kind of shared between VMs (I'm not sure at all this is possible and if possible how to do it). In the meantime exposing the docker daemon over network (with restrictions) to Xen Orchestra would be quick'n easy and I think safe enough if done carefully.

We have just released security updates for xen and blktap. Full details are available on the blog: https://xcp-ng.org/blog/2026/09/08/september-2026-security-updates-1-for-xcp-ng-8-3-lts/

@jcdick1 Ideally you should open a ticket via the Support Portal and provide the tunnel ID there along with a link to this discussion.

On the tuning suggestion, my guess, untested and purely from reading your paste, is that if something is genuinely holding sockets then raising tcp_mem buys headroom rather than stopping the accumulation, and your post#4 about throughput coming back on an xo_server restart points the same way.

It might be worth a mention to @Team-XO-Backend, since they would know whether xo-server keeps sockets per pool.
