Thanks for sharing this. I read your requirements file and have a
question or two.

The first is about what "actions" are. You define it as "structure
elements retrieved from an image format" or "element of an image
structure", which unfortunately doesn't make things much clearer to me.
My guess is that you mean a data structure (like header, L1 table,
refcount block, etc.) and this is the structure that is going to be
modified during the fuzzing? Is this right?

The other thing is that you seem to concentrate on generating test image
(and probably rightly so), but there's also the part that you need to
use that image for something, i.e. using the right actions with qemu to
actually test it against that image in a meaningful way (for example,
corrupting a snapshot's L1 table isn't interesting as long as this
snapshot isn't touched). What are your plans for determining what test
to run against the generated test images?

Also, if you don't mind, I'd like to be CCed on your further emails
about this project.
