@acebmxer Hello, What you're describing sounds more like an RPU issue with Xen-Orchestra than a problem related to XCP-ng updates. But I could be wrong However, since these updates affect Xen, a reboot was clearly indicated in our procedure. So a simple restart of the toolstack isn't enough. You did the right thing by rebooting afterward. Are you using XO Appliance or from source? If it's XO Appliance, you can open a ticket to ask for help analyzing the situation and see if anything in the logs or configuration explains this behavior. If it's from source, for the same issue, I would suggest you start a separate thread on the forum so other users can help you with the analysis In any case, it's great if your pool is working in the end
