On the above attribution, I didn't understand why we would 'hardcode' a
particular image to be checked, it is my understanding that we want to
check systematically all the images after each test.

The above can be put on the class constructor, make qemu_img_cmd a class
attribute.

You don't need the \ to break line in the above statement, you can just
remove it.

Why the use of the preprocessor directive 'kill_vm' here? qemu-img check
doesn't work with the VM turned on?
