Comment 9 for bug 1753394

You can checkout whatever tag of code you're on (16.0.1):

1. git clone <url to nova repo>
2. git checkout 16.0.1
3. cherry pick jay's patch:

git fetch https://git.openstack.org/openstack/nova refs/changes/10/538310/2 && git cherry-pick -x FETCH_HEAD

resolve any merge conflicts if there are any and commit those changes

4. Generate a patch:

git format-patch -1

That will give you a .patch file which you can then apply on your install directory where nova exists (you probably want to also delete those .pyo and .pyc files):
