b)
The raw image file works without any errors after install and reboot.
I created the image file with:
qemu-img create -f raw /volumes/disk2-part2/images/vmtest10-1.img 20G
Changes to the qemu commandline:
-drive format=raw,file=/volumes/disk2-part2/images/vmtest10-1.img,if=virtio,media=disk,cache=writeback \

c)
I can always repeat this behavior since 4.1.0 is out.
I could perform a git bisect. But I need help, I've never done that before.
