      @stormi Yes... I understand that is the way it is supposed to work. 😏

        @danp Well I use UEFI as well, so we do have the same issue here :), still curious in how this can be fixed of course.. I even upgraded to the latest XCP-ng 8.2.0 RC to see if it has been fixed but no luck so far 😞 So I keep my GPU out for a while again or I gotta get a AMD Workstation GPU.

        I have tried every other solution, but no luck so far. I think its either XCP-NG or The MOBO I use (Gigabyte AORUS PRO X570).

          @appollonius Have you tried installing CH 8.1 or 8.2 to see if it will boot without a monitor attached?

            @danp Ehmm no, I dont have an extra host where I can test it on.. Otherwise I wouldve done that with no problem...
            I use a Quadro P400 and you?

                @danp Aha then it should boot without problems though... Strange...

                  @appollonius I don't have this issue. Just been following along on this thread and happened to run across the Citrix issue I posted earlier. 😀

                    @danp Ahh I thought you had the same problem, but I still find it strange and I cannot find anything about it on the interwebs...

                        @danp Yeah though it still does not have any solution... Which is sad 😞

                          @appollonius Found the patch where Citrix backported the fix to XS 7.1 -- https://github.com/xenserver/xen.pg/commit/4629bd92f3d3263da9d7fe304df422e54d56ee56

                          @r1 @stormi Guessing that they didn't pass this upstream to the Xen folks. 🤷

                            @danp thanks, I might be able to somehow tweak this in the EFI config but not 100% sure. Will check this out asap, otherwise I'll have to leave it to the Xcp-NG team

                              @danp So I have another question, do you think that when I install XCP-NG in BIOS mode that this issue wont arise?

                              Now I know what the problem might be @stormi could this be an UEFI issue rather than an XCP-NG issue?

                                @danp said in Strange issue with booting XCP-NG:

                                https://github.com/xenserver/xen.pg/commit/4629bd92f3d3263da9d7fe304df422e54d56ee56

                                This seems present for XCP-ng 8.0 and 8.2..

                                  @r1 Its still strange though that this problem still persists. As I think there are more people using the Quadro P400.. (Correct me if I'm wrong of course).

                                    Do you guys think that this has to do with UEFI? Otherwise I will have to reinstall XCP-NG in BIOS mode instead of UEFI mode...

                                      @appollonius I don't think it is driver issue (POST boot).. We may know more only from serial output.

                                      Are you able to boot as-is in BIOS mode without reinstall?

                                        @r1 I could try that, will update when that has been done...

                                          @r1 How do I boot in BIOS mode without a reinstall? Can that even be done, because I remember that when I installed xcp-ng I had to choose between BIOS or UEFI am I correct? (Could be something else though) otherwise if not I can give that a try.

                                            @appollonius I think it will depend on hardware settings. See if you have option to change the mode in motherboard settings?

                                            I don't have physical hardware access to validate this as I mostly use nested virtualization but XCP-ng /boot has required files support both for UEFI and BIOS mode.

                                            Maybe @stormi can confirm.
