    @dinhngtu said: dinhngtu VATES 🪐 XCP-NG TEAM a day ago @hrvojer There are many bugs in older versions of the Xen PV drivers. I suggest running Windows without guest tools and drivers if you can take the performance and functionality hit (no suspend/migration on UEFI VMs, no metric reporting, etc). Thanks @dinhngtu, appreciated. Running without PV drivers is hard for us: this is an I/O-heavy production SQL Server and we already had timeout problems before adding RAM, so I'm worried emulated disk performance would hurt more than an occasional crash. Our medium-term plan is to migrate SQL to a new VM with a supported Windows Server and current tools. Until then, a few follow-up questions: Is there any official place to still get XenServer VM Tools 9.2.3 (or whichever last version works on 2012 R2)? Would an older XCP-ng PV driver release (e.g. 8.2.2.200) likely be any better here, or is it the same xenvbd code base? One more detail I missed: in the same Feb 2026 change we also enabled "Lock Pages in Memory" for the SQL Server service account (together with 16 -> 64 GB RAM). Is there any known issue between old xenvbd and locked pages / large guest memory? Meanwhile we've capped SQL max server memory at 32 GB as a stopgap.

    The same as @john.c and also XO Lite tends to be less a priority because less critical than the full fledged XO (the priority is to replace entirely XO 5 in the next releases). Why you would need XO Lite outside basic actions? It's mostly meant to bootstrap XO itself and do basic operations (which is already the case, at least with many basic features already). Initially, the goal hasn't moved: replacing XenCenter. We are moving in that direction, but again, I think it's more important to get XO 6 finished first. I'm curious to understand more the use case of XO Lite in your context @unreal-shizzle ?

    @yannsionneau Yes it works Thank you very much, great job Tested on Ryzen 9 9950X / AMD Raphael iGPU Tested the new experimental iGPU passthrough packages. - CPU: AMD Ryzen 9 9950X - iGPU: AMD Raphael (1002:13c0) - XCP-ng: 8.3 - Guest: Bazzite AMD - VBIOS: extracted from the ACPI VFCT and supplied as /root/vbios.bin - iGPU passthrough: working - AMD amdgpu driver: working - Physical HDMI output: working - Bazzite desktop displayed successfully on the physical HDMI port. Ubuntu 24.04.2 was able to initialize the GPU and Vulkan/RADV detected the Raphael iGPU, but the HDMI output went black when the graphical desktop started. Bazzite worked and provided a stable display output. So on my Ryzen 9 9950X, the experimental packages appear to successfully enable Raphael iGPU passthrough and physical HDMI output.

    XCP-ng on a laptop - turning off the monitor

    @abudef I ran into the same thing on a dell latitude 5411, but I eventually found a workaround. In the BIOS under System Configuration there was an option called Unobtrusive Mode, and when enabled, a specific key combination will turn off the display and speakers, independent of the OS. The same key combination will then turn them back on when needed. While an automatic feature would be preferable, the manual option meets my needs since it would be rare to need to use the laptop screen. The one downside for me is that if power is lost long enough that the battery drains, the screen will need manual intervention after power is restored - the BIOS will turn the machine back on when it receives power, but won't put the screen back in its previous state. I put a sticker on the laptop with the key combination so I will remember it when needed.

    @sushant-diwakar I think you misunderstood @olivierlambert as he was referring to the support ticket that you opened with Vates, which is still open and awaiting a response from you. I restored the forum thread that you deleted because it contains information that is pertinent to this discussion. I'm leaving this topic separate for now, but IMO there really was no valid reason to start this new thread instead of continuing the prior one.

    @ImThatFluffy said in Issues with PCIE Passthrough: @john-c Yea im not sure, it was either an issue with the way I had Debian setup or compatibility things booted up Ubuntu 22.04LTS with the HWE kernel and it worked perfectly. Well if you are using Ubuntu Linux 22.04.1 LTS or one of the later point releases then it would be using a Linux Kernel version 6.1 or later, when its a HWE kernel. So any bugs from earlier versions of the kernel would have been fixed, also the Intel ARC graphics hardware would have been released during one of the point releases. On the Debian Linux front a distribution version earlier than version 12.0 would have been unlikely to have complete properly functioning support, due to that release being the first one with the Linux kernel version of 6.1 or later.

    @DustinB said in Imbedded Docker: Has anyone else done this, and can provide benefits or faults in doing so, besides the obvious that this isn't officially supported? I am actually going through the process of trying this right now, and am having significant difficulties with the xscontainer-prepare-vm piece - it doesn't work. So far, I have built a Docker VM, made sure all prerequisites are in there, and then run this script. It does insert an ssh-rsa key into my user's authorized_keys file, but the public key it inserts doesn't actually work. The host is not able to ssh into the VM due to the certificate not matching and requires a password, which does not work because it can't pass the VM check. Has anyone else seen this behaviour before?

    I've got passthrough to work a number of times without issue, the only thing I had to make sure of was that all devices related to the GPU were passed through completely. Are you following the docs step by step? I have a Ubuntu VM running with a 2060 passed through right now, works flawlessly and even survived a power loss on the host.

    @ajpri1998 I agree in regards to XOA getting damaged somehow, so that makes sense. I think my question here to OP was more about why they're concerned with it if they already have XOA. Normally if something happens to XOA though you'd SSH into the XCP-ng host and figure it out from there (which also means XO Lite could be enabled). Not criticizing at all, just was curious about the use case here in specific since it's being evaluated for enterprise use.

    As a general rule, you MUST keep all your hosts up to date. If you update normally, you will be on a 8.2.1

    @Danp said in Patching and trying to Pool Hosts after they've been in production: Warm migration should work in this case because the VM is halted then restarted as part of the process. See here for more details. Sweet, I'll setup something small on the old host for testing and use the Warm Migration process.

    There's no issue to restore everything from scratch, as long as your backup repo (BR/remote) is available. For example, fresh XCP-ng install, deploy XO, connect to the BR and it will find all your previous backups. Then restore, that's it!

    Now we have 76 VMs running on a 3 host pool. Each server has 320 GB of RAM. Our scenario doesn't need big CPU resources so everything works fine.

    @wilsonqanda Yes, BIOS as well, assuming I am remembering right haha. If you just pick whatever is closest and go with it I doubt you'll run into issues, if you do just make a post here and I'm sure someone will be willing to help out or work on a new template or something.
