The images you create with mmdebstrap-autopkgtest-build-qemu require efi. But sbuild-qemu does pass the --boot parameter to autopkgtest-virt-qemu. If you are on amd64 and if your image is for amd64, then autopkgtest-virt-qemu will default to bios boot which is incompatible with the images created by mmdebstrap-autopkgtest-build-qemu. You could add a dirty local hack to sbuild-qemu and let it add --boot=efi via --autopkgtest-virt-server-opt to see if this is it. If that is the problem, please re-assign this bug to sbuild. > or help sbuild-qemu developers to fix sbuild-qemu-update. Did you look up who the sbuild developers are? ;) > Thanks for your time and dedication! Thank you for your bugs!! <3 cheers, josch
