      @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).

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

                        yum update --enablerepo=xcp-ng-ndinh1
                        

                        (updated up top)
