      @andriy.sultanov is there a way to allow all devices (even if we blow up the system lol)

      For example in the docs there a usb filter list you can edit
      /etc/xensource/usb-policy.conf

      anything similar for pcie? Can something be added with disclaimer you break it on you etc?
      Maybe make it a command line option to disable the pci device filters for users that want to pass through special devices.

        @marcoi Right now it's hard coded. But we'll see what could be the best approach on this 🙂

          @olivierlambert thanks for the update.
          and just to confirm, if a device is not showing up in xe list with uuid, there is no way to pass it to a VM correct?

            No, you can pass it anyway, it's just not doable via XO. But the CLI method should work 🙂

              @olivierlambert to confirm the steps
              i can skip this step since it isnt showing up anyways

              • xe pci-disable-dom0-access uuid=<pci uuid>

              then use

              • xe vm-param-set other-config:pci=0/0000:04:01.0 uuid=<vm uuid> to add it to vm

                That might work indeed. If it doesn't, you'll have to go via the old method:

                /opt/xensource/libexec/xen-cmdline --set-dom0 "xen-pciback.hide=(0000:04:01.0)"

                Please let us know 🙂 (this way we could update the doc)

                  xe vm-param-set other-config:pci=0/0000:c6:00.0 uuid=45d0f537-9076-b395-1fbd-850d2cc0cf68

                  This command worked. I was able to pass through the usb and also pcie devices i can get to using XO.

                    Perfect! It's just a matter of stuff hidden for some reasons, at least it doesn't cause any problem, which is what matters 🙂

                          is there anyway to block igpu from being used by xcp-ng during boot? I have it setup for pass through but it fails under the VM. I think it because xcp-ng still displaying the console screen and does not want to give it up.

                            so it seems like when i make the igpu pass through, i see the starting lines of xcp-ng but it never gets to the console screen. which is what i expect.
                            When I add the pcie devices (igpu/hdmi audio) to a vm and start it up, I get and update to the screen and it shows a red number counting which is part of the console.
                            So it seems that when the VM re-initializes the igpu, dom/xcp retakes it over.
                            I confirmed that by using the keyboard to move around and it reshowing the console and filling the missing details as i move around.
                            So why is the dom/xcp retaking the video device over again when it should be blocked from accessing it?

                              @andriy.sultanov Hi, I am having the same issue. Many PCIe USB cards aren't showing up in XO. Any updates if/when this might be fixed? Being able to configure PCIe passthough from the web UI is a really useful new feature and it would be really cool to be able to fully make use if it.

                              Below as requested my list of items that don't show up:
