      @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.

              @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 🙂
