I was unable to run imagefactory to make an OVA.

Downgrading Oz to 0.16.x worked... unsure whats going on debugging the python code here.

I would have assumed 0.16 -> 0.17 is a minor change vs API change :(

Yep, and it is. We generally take API backwards compatibility seriously, not sure what is going on there.

Neither, I've downgraded for now, at least i can build OVA images now, tried debugging the code, but I don't understand why that class import is failing.
