Great, thanks for the additional info! It sounds like maybe something to do with our sparse detection on APFS is broken. Maybe lseek calls are failing? This is a bad problem because it means that any read from an APFS source could break similarly.
I'm still a bit tied down with other work at the moment, but I will try to address this prior to the 3.0 release if nobody else gets to it first. -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1776920 Title: qemu-img convert on Mac OSX creates corrupt images Status in QEMU: New Bug description: An image created by qemu-img create, then modified by another program is converted to bad/corrupt image when using convert sub command on Mac OSX.
