v1: https://lists.nongnu.org/archive/html/qemu-block/2020-06/msg00992.html Hi, I think that qcow2 images with data-file-raw should always have preallocated 1:1 L1/L2 tables, so that the image always looks the same whether you respect or ignore the qcow2 metadata. The easiest way to achieve that is to enforce at least metadata preallocation whenever data-file-raw is given.
Thanks for the review, applied to my block branch: https://git.xanclic.moe/XanClic/qemu/commits/branch/block Max
