Hi, Okay, so this image has the same “issue” (it's intentionally broken, so it's not really an issue) as the one in bug 1355738: There are corrupted L2 entries which are impossible for qemu to repair. Therefore, we could only ask the user to use qemu-img convert and that's all we can do. Therefore, I'm marking this fixed as well.
