      Double check your NTP settings, if it tells it's not sync, it's not sync.

      Note: XCP-ng now uses chrony, but in XO, ntpq -p will give you NTP stats

        Okay so today I upgraded to XCP-NG 8.2.0 but unfortunately it did not solve the issue with XCP-NG not being able to boot without a display attached to the GPU. Also I am getting the EFI_MEMMAP issue and I don't know if this issue has a relation to the GPU.

        If someone has suggestions which I may try, please do so and I will test it 🙂

          @appollonius Are you booting on BIOS or UEFI mode? I ran across this issue earlier today that sounds exactly like what you've described.

          If this is the same issue, then I wonder why the "fix" hasn't made it into xcp-ng. 🙁

            We include all fixes from XS tree into XCP-ng (or those not included are completely analyzed to be sure about it)

              @olivierlambert Wasn't trying to imply otherwise. I was more suspicious that their "fix" never made it into the public view.

              Did you happen to review the issue I linked?

                According to the issue it was fixed in CH 8.0, so it was in XCP-ng 8.0 too.

                  @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?

                              @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..
