some observations:
I can't get infos from qcow images created under windows with qemu-img
under linux.
Qcow images created under linux and windows for the same base file,
don't differs only by the path of the base file.
I don't know if this is normal or not.
Here is two hexdump from qcow images created under linux and windows:
