Hi, I am requesting the exception for the feature "Add ability to inject routes in interfaces.template". The potential changes in Nova are limited as the feature is opt-in. The default interfaces.template is not changed for the reasons now explained in the new commit message. No comment were made so far requiring code refactoring, only ones about procedural technicalities. Furthermore, this code has been running in a production environment for months without any issue. The blueprint: https://blueprints.launchpad.net/nova/+spec/network-template-routes-injection The change: https://review.openstack.org/#/c/115409/ Thanks -- Mathieu
