Does the problem happen only when the image is on APFS? when the destination is on APFS? Neither? Try to see if it's the filesystem. Use OSX to convert images on a non-APFS formatted external drive to see if that improves your luck. I'm assuming this is a duplicate of 1776920 which is still open because we have no OSX developers willing or able to debug this problem. ** This bug has been marked a duplicate of bug 1776920 qemu-img convert on Mac OSX creates corrupt images -- You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1835477 Title: Converting qcow2 to vmdk on MacOSX results in a non-bootable image Status in QEMU: New Bug description: When using qemu-img convert -O vmdk with version 3.1.0 or 4.0.0 on OSX (10.14.3) with a qcow2 image (https://cloud- images.ubuntu.com/bionic/20190703/bionic-server-cloudimg-amd64.img), the resulting image is not bootable.
