It turns out that the image was really corrupted, in fact qemu cannot use it (it says unbootable disk). It was qemu itself that corrupted it, but I fear this is another problem, and I can not reproduce nor diagnose it.
So I think this bug should be closed, unless someone wants to see the corrupted image. -- qemu-img convert: error while reading https://bugs.launchpad.net/bugs/352785 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-b...@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs -- universe-bugs mailing list universe-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/universe-bugs
