Comment 26 for bug 1776920

Hey there! I tested @wkozaczuk's suggested minimal steps and THEY WORKED FOR ME!!

The steps executed on my mac:
1. dd if=boot.bin of=image.img > /dev/null 2>&1
2. dd if=lzloader.elf of=image.img conv=notrunc seek=128 > /dev/null 2>&1
3. qemu-img convert image.img -O qcow2 image.qemu
4. qemu-img convert image.qemu -O qcow2 image2.qemu

The end result:
-rw-r--r-- 1 *** *** 6684672 Jun 22 14:19 image.img
-rw-r--r-- 1 *** *** 7012352 Jun 22 14:20 image.qemu
-rw-r--r-- 1 *** *** 7012352 Jun 22 14:20 image2.qemu
-rw-r--r-- 1 *** *** 6750208 Jun 22 14:22 image2.vbox

The result of regular compare:
qemu-img compare image.qemu image2.qemu
Images are identical.

The result of strict compare:
qemu-img compare -s image.qemu image2.qemu
Images are identical.

Qemu-img on my Mac:
qemu-img --version
qemu-img version 6.0.0
