              Hi all, here's a pre-build of the fix for anyone who wants to test (8.3 only):

              wget https://koji.xcp-ng.org/repos/user/8/8.3/xcpng-users.repo -O /etc/yum.repos.d/xcpng-users.repo
              yum update --enablerepo=xcp-ng-ndinh1

                @dinhngtu will be released also for 8.2.1?

                  8.2.1 is EOL: https://xcp-ng.org/blog/2025/09/16/xcp-ng-8-2-lts-reached-its-end-of-life/

                    @dinhngtu On a quick test, the ISO boots and installs. When the VM boots from the HD it crashes (and on reboots).

                    Updating XCP 8.3 with qemu-4.2.1-5.2.12.2~fixvwc1.1.xcpng8.3.x86_64 solves the issue and the installed windows image boots correctly without any additional changes.

                        @olivierlambert this problem can cause a crash on update of windows 2025 VM on xcp-ng 8.2.1 or remains only a problem for fresh install?

                          8.2 is EOL, and also IDK how it's affected by this issue.

                            @francesco-maria I haven't determined what exact conditions would trigger the issue. It seems to only happen on new installations for now, but it could very well change in the future. Though as long as you keep the Xen drivers installed, things should be OK.

                                Hello all, the new test build qemu-4.2.1-5.2.12.2~fixvwc2.1.xcpng8.3 is now available.

                                If you have tested the fix before, you can update with this command:

                                yum update --enablerepo=xcp-ng-ndinh1

                                  @dinhngtu Same results with the updated qemu-4.2.1-5.2.12.2~fixvwc2.1.xcpng8.3.x86_64. The Win2025 VM (without Xen tools) fails to boot correctly using stock XCP 8.3 but starts correctly with the fixvwc patch. (no actual performance or other testing done).

                                    @Andrew said in Windows 2025 Standard 24H2.11 (iso release of sept 25) crash on reboot with "INACCESSIBLE BOOT DEVICE 0x7B" in XCP 8.2.1 and XCP 8.3:

                                    fixvwc patch

                                    Having the same isaue with a new Windows Server 2025 VM , tried to get the updates but it failed also, see attached

                                          @coconutit I made a mistake with the command, it should be:

                                          yum update --enablerepo=xcp-ng-ndinh1
                                          

                                          (updated up top)
