User support guide

To assist you in handling user questions or requests, here are a few common problems that have been encountered over the years, and how to solve them (please add if any new ones come up!)

Networking

User cannot delete Neutron network

Usually this is because the user does not understand the dependency-order of all the Neutron abstractions. In order to delete a network, one first must remove its subnets from any routers, then delete the subnets, and finally delete the network. It is such a common operation that python-chi maintains the nuke_network helper.
