      Relevant logs, from daemon.log:

        @stormi My apologies. Normally I relish the opportunity to dive deep into logs, however, in this case I am also the treasurer of my church and I have year-end accounting tasks to accomplish, so haven't had much time to dedicate to this.

        Additionally, since I don't really know what I'm looking for in the logs, I figured it's be best to share it on hear for the community to take a look...lol.

          @stormi Yikes! If you're spooked by this error, then what does this mean for me?

          By the way, this very VM imported and started up without any issues on a physical XCP-ng host. This issue seems to be happening in a nested virtualization setting - where XCP-ng is the nested hypervisor (a guest of VMware Workstation Pro).

            @kagbasi-ngc Don't do nesting! It's not to be trusted even when it seems to work.

              @manilx Yeah, not doing it in production, just in a test environment. Plus I only did it because I actually found a write-up by the Vates team on how to get it done, which confirmed to me that while they don't recommend it for production, they understand that it has some merit in a testing environment and want to see it working.

              That said, I definitely hear your admonition and would never do it in a production setting.

                I'm not spooked, I just think it's the relevant error message we need to understand :).

                Since this is a test pool, could you make it use the debug version of OVMF?

                ln -sf OVMF-debug.fd /usr/share/edk2/OVMF.fd 
                

                Then attempt to start the VM again, and get /var/log/daemon.log and /var/log/xensource.log once again.

                  @stormi Glad you're not spooked.... 👍

                  I'll enable the debug mode as you'd instructed and grab the logs for you shortly.

                    @stormi Hi there, as requested, here are the two logs:

                    • daemon.log
                    • xensource.log

                    I started the VM at timestamp Dec 13 13:54:59 and stopped it at Dec 13 13:55:59.

                    Now, is deleting the symbolic link created above all that is necessary to reverse the debug mode?

                      @stormi @kagbasi-ngc I have this same error in a separate thread, however, there is no nesting involved. from my limited knowledge, it seems like xcp is not seeing the available memory resources during boot and fails. if I migrate a running VM to the same host that gives me this error, it will operate as expected. but, after reboot... failure to launch.

                      @olivierlambert Thanks for your help so far.

                        @kagbasi-ngc Looks like we missed something, as the log indicates it loaded OVMF-release.fd:

                        Dec 13 13:54:59 VMH01 xenguest-2-build[8345]: Loaded OVMF from /usr/share/edk2/OVMF-release.fd
                        

                        We'll come back to you with a better test procedure.

                        For now I just have a quick and dirty one, consisting in overwriting the release file with the debug one:

                        cp /usr/share/edk2/OVMF-debug.fd /usr/share/edk2/OVMF-release.fd
                        

                        You can revert this change with yum reinstall edk2.

                          @stormi Sorry for the delayed reply. I did as you requested, and below are the resulting log files. I started the VM at timestamp Dec 17 14:43:34 and stopped it about 2 minutes later.

                          • daemon.log
                          • xensource.log

                          If I can be of assistance, don't hesitate to ask please. Thank you.

                            @kagbasi-ngc @Mefosheez We're trying to find developer time to diagnose the cause, but it's not the best time of the year, so I can't promise anything on delays.

                              @kagbasi-ngc Does your VM have a vTPM? If so, could you try without?

                                  @stormi Yes it does. I just deleted the VTPM and tried starting it, but no success. Still the same issue - can't initialize the display.

                                  I also disabled Secure Boot, and got the same results.

                                      @stormi I wanted to follow up. I saw a good number of patches available today, first updates since the issues started for me. I processed them, but this issue still seems persist.

                                      I know this thread is about nested virt, and i don't want to derail that. this is where i had posted about the issue prior. I believe they are going to be tided to the same root. any help would be appreciated.

                                        @Mefosheez I forwarded internally. Feel free to ask again after a week if no answer comes.

                                          @stormi I marked it as a question about a week ago now. do you suggest making a new post as a question all together?

                                            @Mefosheez Marking a new post as a question will not be necessary. @anthonyper is the one working on what we think is the issue (a regression on the EDK2 package). I haven't heard of a fix yet, but it's in progress.
