      Same answer than the other topic, checking first the basics before investigating further 🙂

        @olivierlambert I'm going to swap in an AMD card today and will let you know if anything changes!

          My issue isn't that I can't pass through the card at all, I can still do it via CLI just fine so there isn't really any real problem preventing me from hiding the card from dom0 and then attaching it to my Plex VM. I was just curious why some devices are listed with xe pci-list and others aren't because I would have thought that it would essentially just reflect whatever shows in lspci.

          Having it show in xe pci-list would just mean it's easier to attach/detach from a VM as it would then show in the webUI.

          Does XCP-NG require the built in driver support to list the devices in pci-list?? Because the TV tuner doesn't work natively on Linux without downloading the drivers so I guess that could be a possibility?

            @Pyroteq OK so it's more clear to me now. So there's an issue on how we report all the devices to make it doable via Xen Orchestra. I'm not sure exactly who to ping, maybe @Team-Hypervisor-Kernel

              im seeing a similar thing in lastest version of XO (self built)
              lspci showing more items the XO is showing for the host.
              I just added a usbc card for example and its not showing up in XO.

                Just to add details about my box. Seems lspci is showing 20 items and xe/xo is only showing 12.
                I left the device name in the second list to help show whats not showing up in xe vs lscpi

                XE/XO list

                  Just adding here from my other post---AMD card didn't not reproduce this issue but my Intel Arc card experience matches exactly what others have posted here about the LSPCI vs XE-Assignable / XOA list difference.

                    @chicagomed If lspci shows the PCI device in its output we probably need to check if XAPI layer "sees" all this devices and correctly reports them to XO. Ping @Team-XAPI-Network

                      @chicagomed Could you (and others with the issue) please post the output of lspci -mnn for the devices that are not shown in xe pci-list?

                      XAPI filters for PCI devices with classes 01XX, 02XX, and 03XX as a safety measure (better to be safe than sorry in avoiding passthrough of critical devices), but perhaps we could reasonably expand this filter.

                          @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.

                              @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.
