Basic Setup

In order to use Neutron with devstack (http://devstack.org) a single node setup, you'll need the following settings in your local.conf (see this page for more details on local.conf). 

[[local|localrc]]
disable_service n-net
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
# Optional, to enable tempest configuration as part of devstack
enable_service tempest


Then run stack.sh as normal.

If tempest has been successfully configured, a basic set of smoke tests can be run as follows: 

$ cd /opt/stack/tempest
$ nosetests tempest/scenario/test_network_basic_ops.py


See the Neutron Admin Guide for details on interacting with Neutron: http://docs.openstack.org/trunk/openstack-network/admin/content/index.html

XS/XCP Setup

See the following page for instructions on configuring Neutron (then called Quantum, which tells you how old the linked doc is) with OVS on XS/XCP: QuantumDevstackOvsXcp

Multi-Node Setup

A more interesting setup involves running multiple compute nodes, with Neutron networks connecting VMs on different compute nodes.

You should run at least one "controller node", which should have a localrc that includes at least: 


disable_service n-net
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
enable_service neutron


You can then run many compute nodes, each of which should have a localrc which includes the following, with the IP address of the above controller node: 


ENABLED_SERVICES=n-cpu,rabbit,neutron,q-agt
SERVICE_HOST=[IP of controller node]
MYSQL_HOST=$SERVICE_HOST
RABBIT_HOST=$SERVICE_HOST
Q_HOST=$SERVICE_HOST


Note: the need to include 'rabbit' here seems to be a bug, which may have been fixed by the time you're reading this.If 'rabbit' is not specified, nova-compute also will try to connect to rabbit on localhost, not the "controller host".
