Hey,

nice catch. That is interesting, because we leverage imgfac to do the ova wrapping.
Looking at the code we use to trigger the ova creation, I do not see any size related code.

Which means that imgfac is identifying the size of the image by itself and writing those values.

And looking at the imgfac history I see this commit:
https://github.com/redhat-imaging/imagefactory/commit/ee8bdd4a8df8669cacf4ab6e1e9c00c7a08e0862

which landed in master recently (we use imgfac master for building).

I've commented on the fix, and adding Ian as the author of that patch.
