The buildroot was: /var/tmp/build-root/standard-aarch64/.mount

It tries to use qemu-system-x86_64, which I have traced back to .oscrc containing build-type=kvm. Since this does not appear to work, can obs-build please emit a warning/hint that such configuration is unsupported.

adrianschroeter commented 1 year ago

such a config could be supported via injecting a x86_64 kernel and qemu user land setup...
