I've a base image of a windows10 machine.
[win10_base image].qcow2 -- [overlay_with_bug].qcow2
I have a bug of a app which I can reproduce. This bug does alter something on the system.
I want to reproduce the bug on a innocent windows VM. All changes should be tracked in the overlay of this image. How can I retrieve the changes stored in the overlay? Which format would be best? Is there something like a compare/Analyse tool for VM-Images?
