      Hi,

      Can you tell more precisely what do you want to achieve functionally speaking?

        @LuisRiveraSig What chipset is used for the serial ports? My guess is that it's a special MOXA serial chipset (non-16550) and requires a special driver that XCP/Xen does not natively support.

          @olivierlambert We are trying to migrate from VMWare to XCP so we want to enable those two on-board serial ports, the goal here is to be
          able to communicate with them.

            @Andrew It uses ITE8786E. Where could we find drivers for this?

              @LuisRiveraSig What are you trying to use the serial ports for?

              • XCP console?
              • Dom0 Serial port (ie. UPS monitor)?
              • DomU/VM?

                  @LuisRiveraSig Since the device is not need for Xen Console or Dom0 then you can try a PCI pass-thru to the VM or use a USB device and pass it to the VM and just use the needed driver in the VM directly.

                    I too would like to pass thru a serial port on Dell R460 server host to a vm running linux. I would like to use this to talk to a lighting system with this VM rather than using a stand alone desktop.

                      @Double-e If you serial ports show up as a PCI or USB device then you can pass it to a VM. Most normal on-board serial ports can not be directly used in a VM.

                      Use lspci and lsusb to check your devices.

                        @Andrew I did not see a serial port listed. I'll just get a USB version and plug in to server and see if I can pass thru it. If it works, I can get rid of another Destop server and be fully virtual.
                        Thanks for your hellp.
