Comment 1 for bug 1204204

Oh look, there's a bug for this. I've submitted a patch that simplifies running generate_sample.sh in Nova. With that it should be possible to run it with no parameters as long as you're in the root of the Nova tree (as in the examples above).

The change is here and I'll add this bug to the commit message when I get a chance: https://review.openstack.org/#/c/43160/
