We already upgraded Image Factory some time ago, to be able to generate images for Hyper-V. Unfortunately, we were hold back by the lack of a newer stable release of Koji, which passes the right parameters to Image Factory.
I tried to backport Ian's changes to Koji 1.10.1 (which I assume we're using). I had to manually fix a few merge conflicts - could someone take a look at the attached patches? I have no possibility of testing them here.
Thanks, Laurențiu
