      You were correct. It had two items for the NVIDIA GPU to pass through. However, it still did not show after getting passed, assigned, and rebooted.

        That's expected, displaying PCI passed in the UI will come in few days now šŸ™‚

          Still, despite the display issue, does it work now?

            @olivierlambert Something is still off. When I run the Nvidia-smi command, I get an unknown error after installing the NVIDIA Drivers.

                  @Dean50 something strange is going on. I turned on transcoding in the Jellyfin console. It seems that the transcoding is working when it is switched on, but it is not providing audio. Regardless, it seems that XCP-ng is passing through the GPU as it is intended. Thanks for all your input. Greatly appreciate the support.

                      I was able to get things working. Even though it does not show in the GUI on XO, it works for transcoding. However, I cannot complete a backup of that particular VM with this error...

                        1. Excellent news for being able to rely on the GPU šŸ™‚ So the driver accepted to install? What did you change?
                        2. The UI with real PCI passthrough displayed is now available in latest XO.

                          I thought because the nvidia-smi command showed an error that it did not pass through correctly. I went into the Jellyfin app and set it to use Transcoding, and it worked. Now, the only problem is, for some reason, I can't get that particular VM to complete a remote Delta backup. I continue to get the error shown above. I've deleted the job and rebuilt it, but get the same error. Any ideas? I really need to back up this media server. Thanks again.

                            The reason why is written in caps: VM HAS PCI ATTACHED. You can't snapshot live a VM with a PCI device attached. A possible trick: use "Offline snapshot" in your backup job, that might work.

                              @olivierlambert yes, the reason was quite obvious. A solution is what I was looking for. I will definitely try it with offline snapshots. Appreciate the info.

                                  @olivierlambert That worked. I selected an offline snapshot, and the job was completed. Thanks again.
