That means that we have to add another filter line every time some format gets a new creation option. This can be avoided by instead discarding everything and just keeping what we know is format-independent (format, size, backing file, encryption information[1], preallocation) or just interesting to have in the reference output (external data file path). Furthermore, we probably want to sort these options. Format drivers are not required to define them in any specific order, so the output is effectively random (although this has never bothered us until now). We need a specific order for our reference outputs, though. Unfortunately, just using a plain "sort" would change a lot of existing reference outputs, so we have to pre-filter the option keys to keep our existing order (fmt, size, backing*, data, encryption info, preallocation). Finally, this makes it difficult for _filter_img_create to automagically work for QMP output. Thus, this patch adds a separate _filter_img_create_for_qmp function that echos every line verbatim that does not start with "Formatting", and pipes those "Formatting" lines to _filter_img_create. [1] Actually, the only thing that is really important is whether encryption is enabled or not. A patch by Maxim thus removes all other "encrypt.*" options from the output: https://lists.nongnu.org/archive/html/qemu-block/2020-06/msg00339.html But that patch needs to come later so we can get away with changing as few reference outputs in this patch here as possible.
