      Hello, Im having an issue passing through a GPU into my system, When I add the PCIE device in the UI and attempt to boot the machine I recive a NO_HOSTS_AVAILABLE error.

      The GPU and SR on "xcp-ng-hv-2 R730"

      I have a GPU in all three Servers all of different types

      There is a
      NVIDIA Tesla P4 in HV-3 (fails)
      Intel Arc A380 In HV-2 (fails)
      NVIDIA Quadro P400 HV-1 (Will pass through)

      Bellow is the error I get when attempting to boot the VM on HV2 with the Intel Arc A380 passed through.

      I get the same flipped around when attempting to pass the Tesla P4 on HV-3

      vm.start

    at Api.#callApiMethod (file:///usr/local/lib/node_modules/xo-server/src/xo-mixins/api.mjs:445:20)"
}

      IOMMU is enabled and the VM will boot without the PCIE device attached Im not sure what the issue might be, ive read the PCIE Docs and everything looks ok.

      Any help is appreciated 🙂

        This means XAPI couldn't find a host where it could boot with both the storage and the available GPU. So the error is logical on hv-3 & hv-1.

        For hv-2, have you passed all the PCIe identifiers correctly? Eg show us an lspci on your Dom0.

            Don't mix between vGPU and PCI passthrough. It might be the issue. Please only use the CLI. vGPU and PCI passthrough are different beasts. Focus on https://docs.xcp-ng.org/compute/#pci-passthrough only, be sure to have nothing vGPU related enabled anywhere.

              You need to attach the GPU to the VM via CLI, rather than using the vGPU option, that is an entirely different thing than passthrough (vGPU, in short, lets you slice certain GPUs so more than 1 VM can use a single GPU, it's cool but very limited right now).

              Follow the docs like Olivier mentioned and things should go smoothly. I've passed through GPUs a number of times now and they work quite well. Only thing to note is that some GPUs will show their audio devices as an additional PCIe sub device (IDK the right terminology) and you have to make sure to pass the entire device through, not just the GPU portion.

              Looks like Intel doesn't do this, but with NVidia for example, you'd have 84:00.1 (possibly more, like .2 etc...) and you have to be sure all are passed through. At least I had to, to get mine working.

                @planedrop I somehow just misread a bunch of stuff. PCIE pass through seems to be working okay.

                But the device is not showing up in the /dev/dri directory and I cant figure out why?
                Any help would be appreciated.

                  @ImThatFluffy are you sure it's working as it should then? I believe it should show up, I'll try some testing in my lab but if you passed through correctly then I think it should show up in /dev/dri just fine.

                      @ImThatFluffy Maybe try running a GPU load on it and installing Nvidia SMI to see if the GPU is being used?

                        @planedrop I cant get the GPU to pull anything without it being in /dev/dri/ & its a intel ARC GPU SMI is going to be pretty pointless AFIAIK.

                          @ImThatFluffy Oh yes, sorry, forgot this was an ARC GPU.

                          Have you tried getting the ARC drivers installed? I imagine they should work if it shows up in lspci.

                          I've never passed an ARC GPU through though so it's possible there's something additional needed to get it going.

                              Are you sure your device doesn't have another PCI address? (like some graphic cards got the GPU at a PCI address and the HDMI/sound to another, if you don't pass both the driver will fail to load)

                                LSPCI on the host shows this

                                Im currently only passing 84:00.0 through I will attempt to pass 85:00.0 through as well and re update.

                                  Yes, please hide both from the dom0 and pass both to the guest, start again and I think that might work 🙂

                                      Hmm that's weird 🤔 Anyone else around using an ARC card in passthrough?

                                        @ImThatFluffy Have you installed the firmware for the card that your proposing to pass through? That way you can be sure that the card is fully functional.

                                        I read in an article about getting the card working written during 2023 that it requires the firmware to be installed (present) on the Linux system along with the compatible drivers.

                                        So you may be missing the firmware also is all parts of the Intel Arc drivers fully installed on the system for the device to fully function?

                                          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.
