As discussed in the mailing list [1] since cells v1 has been deprecated since Pike and the biggest user of it (CERN as far as we know) moved to cells v2 in Queens, we can start rolling back the cells v1 specific documentation to avoid confusing people new to nova about what cells is and making them understand there was an optional v1. There are still a few mentions of cells v1 left in here for things like adding a new cell which need to be re-written and for that I've left a todo. Users can still get at cells v1 specific docs from published stable branches and/or rebuilding the docs from before this change.

Command-line Utilities
In this section you will find information on Nova's command line utilities.
Nova Management Commands
These commands are used to manage existing installations. They are designed to be run by operators in an environment where they have direct access to the nova database.
nova-manage nova-status
Service Daemons
The service daemons make up a functioning nova environment. All of these are expected to be started by an init system, expect to read a nova.conf file, and daemonize correctly after starting up.
nova-api nova-compute nova-conductor nova-novncproxy nova-scheduler nova-serialproxy nova-spicehtml5proxy
WSGI Services
Starting in the Pike release, the preferred way to deploy the nova api is in a wsgi container (uwsgi or apache/mod_wsgi). These are the wsgi entry points to do that.
nova-api-metadata nova-api-os-compute
Additional Tools
There are a few additional cli tools which nova services call when appropriate. This should not need to be called directly by operators, but they are documented for completeness and debugging if something goes wrong.
nova-rootwrap
Deprecated Services
The following services are deprecated in nova. They should not be used in new deployments, but are documented for existing ones.
nova-dhcpbridge nova-network nova-consoleauth nova-console nova-xvpvncproxy
