        @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.

                      Hi @kagbasi-ngc, I believe I've got a fix for your current issue, do you want to give it a try? @Mefosheez it's probably going to work for you as well.

                      I've prepared an update, could you install it?

                      # Download repo file for XCP-ng 8.3
                      wget https://koji.xcp-ng.org/repos/user/8/8.3/xcpng-users.repo -O /etc/yum.repos.d/xcpng-users.repo
                      
                      # Update edk2
                      yum update --enablerepo=xcp-ng-aperard1 edk2
                      

                      Alternatively, the RPM is there: https://koji.xcp-ng.org/repos/user/8/8.3/aperard1/x86_64/Packages/edk2-20220801-1.7.7.1.0.enomemfix.1.xcpng8.3.x86_64.rpm

                      And if you are curious about the change, it's explained in there https://github.com/xcp-ng-rpms/edk2/pull/4

                      Cheers,

                      tperard opened this pull request in xcp-ng-rpms/edk2

                        @anthonyper said in Imported VM Starts but Does Not Initialize the Display:

                        yum update --enablerepo=xcp-ng-aperard1 edk2

                        confirmed with ubunutu desktop 24.02 in uefi. i can confirm windows later today but this looks to be the fix. will this be folded into an upcoming release?

                          @Mefosheez Does your host not have large HAP size?

                          Please show the output from xl dmesg | grep HAP on your XCP host.

                            [08:30 xcp-r630 ~]# xl dmesg | grep HAP
                            (XEN) [ 2.581645] HVM: Hardware Assisted Paging (HAP) detected
                            (XEN) [ 2.584428] HVM: HAP page sizes: 4kB, 2MB, 1GB

                            This is not something I have ever adjusted or set prior.

                              @Mefosheez @anthonyper If it solves the problem, then great!

                              You can't set or change HAP, it's what the CPU chip supports. I was looking at the notes for the change and part of it is related to hosts that have small HAP sizes (ie, 4K, 2M, not 1G). As there are other updates in the same version the issues must have been fixed by a different part of the patch.

                                YES - you fixed it! Thank you!!!
                                I tried the package and it worked - the VM started and was able to initialize the display and finish booting up. Glad you found the issue and I'm even more glad that it was my report that prompted you to look into this. This is a true testament to the power of this community.
