In the termbin:
So the "good" one is on the left, and the "bad" one is on the right. The
bad one is ... completely blank for the first 200+ MB? That's not great.
so:
.bin.apfs: broken raw file, made on apfs, no arguments(?)
.bin.apfs2: broken raw file, made on apfs, `-S 0` ?
.img.org: qcow2 file
The image apfs2 here is created with "-S 0"and the .bin is a working one
generated on a ubuntu machine.
Strange thing is that this say they are identical:
$ time qemu-img compare -f qcow2 -F raw
coreos_production_openstack_image.img.org
coreos_production_openstack_image.bin.apfs
Images are iden
Adding "-S 0" on the APFS convert only makes the file 8.5Gb but its still "bad".

qemu-img convert qcow2 to raw fails on OS X

I tried to make a quick grep of the start of the disk in the "bad" raw image
and it does not exist anywhere so there is more ot it then just a offset issue.
rg -M 20 -a --encoding=ascii '\xeb\x63\x90\x00\x00\x00\x00\x00\x00\x00\x00\x00'
coreos_production_openstack_image.bin.apfs
or
rg -M 20 -a -
I gave it a try here:

Its only the first 4096 bytes.

We've had APFS bugs before, if memory serves... perhaps something to do
with sparse gap handling?
Do you have the ability to take a "good" conversion of the qcow2 file
(made on a non-APFS partition) and compare it against the "bad"
conversion?
Highlighting the differences might inspire some ideas
