Thanks for testing.

I re-test the dmg img with QEMU 4.0 again, and it works. In my opinion, the bug can be closed as "Fix released".

Since QEMU 4.0 has been released now, I assume we can close this ticket as "Fix released"?

Hi Yu-Chen. The series looks good. It fixed the problems related to zero chunk. Nice work! I added a comment that I reviewed your patch considering my scenarios here.

Because of lacking zero chunk table, reading zero sector will return EIO. I have submitted a series to fix this problem.
