@vxgmichel Update installed and running. Rolling pool reboot failed waiting to evacuate an empty host, I can't blame the update.

Interesting. Worth a report to XO team?

@JamesG Thanks. I'll let @teddyastie see. I think he would be more confortable with having the card in our lab, which should be imminent now, but I won't speak for him.

But I would in any case where PCI passthrough for edge cases like the GPU marked kind of is, is not a requirement, Always recommend XCP-ng over the others.

Thanks for that :).

There's no problem to state faithfully what works and what doesn't with a solution, and adapt the advice to the actual needs.

I just felt compelled to react because I didn't find it entirely right to state that GPU passthrough has low priority. It's supported in general, but there are devices that come with technical challenges not fully addressed yet in Xen or in XCP-ng, and we treat that as part of the general hardware support we aim for.

Same as we work on device drivers for devices mostly found in home labs, without dismissing them as low priority.

And it's a good point to state that the needs around GPUs are growing fast due to AI, indeed.

99 percent of the dev team is working security and basic hypervisor

The numbers don't match any reality though. Yes, maintenance is important, but we have a developer working on AMD iGPU passthrough fixes, and Teddy here is following the Intel Arc topic closely and obtained hardware (waiting for it to be available in the lab). We also work on AMD MxGPU for vGPU support on the supported devices. We also have work on virtio-gpu. Without producing something that can become an actual feature yet, as it's complex, but there's clearly investment on those fronts.

CCing @Team-XAPI-Network and @Team-Hypervisor-Kernel for them to have a look at this strong vs weak host model and the impact on HA.

its scary that GPU passthrough still has a low priority for XCP-ng, during the boom of AI and local LLM Inferencing.

As XCP-ng product owner, and someone who sees how much work developers put into such topics, may I ask you to elaborate on this "has low priority" statement?

Spoke to soon. While the updates succeeded, one of the nodes is rebooting every few minutes due to an HA self-fence.

Could you open a dedicated thread and ping me there?
