Networking
Some of what customers can do on a network depends on Neutron extensions. OSIE reads a cloud's list of extensions from Neutron and offers a feature where it finds that feature's extension. OSIE has no setting for them, and the admin dashboard does not show which ones a cloud has.
To see what a cloud offers, list the aliases of its extensions:
openstack extension list --network -c Alias -f value
📄️ Firewalls
What OSIE requires of a cloud to offer firewalls: the FWaaS v2 extension of the Networking API.
