my setup : one db host(db service), one glance host(glance service), on api host(keystone,nova-api,nova-scheduler, nova-conductor, quantum-server,quantum-dhcp, quantum-l3-agent,quantum-plugin-openvswitch-agent), eight compute host(each host with nova-compute, quantum-plugin-openvswitch-agent), i check that all the service on all hosts works well

i used vlan type network and openvswitch plugin:

my quantum.conf


Default log level is INFO

verbose and debug has the same result.

One of them will set DEBUG log level output

debug = True

Address to bind the API server

bind_host =

Port the bind the API server to

bind_port = 9696

Quantum plugin provider module

core_plugin =

core_plugin = quantum.plugins.openvswitch.ovs_quantum_plugin.OVSQuantumPluginV2

Advanced service modules

service_plugins =

Paste configuration file

api_paste_config = /etc/quantum/api-paste.ini

The strategy to be used for auth.

Supported values are 'keystone'(default), 'noauth'.

auth_strategy = keystone

Modules of exceptions that are permitted to be recreated

upon receiving exception data from an rpc call.

allowed_rpc_exception_modules = quantum.openstack.common.exception, nova.exception

AMQP exchange to connect to if using RabbitMQ or QPID

control_exchange = quantum

RPC driver. DHCP agents needs it.

notification_driver = quantum.openstack.common.notifier.rpc_notifier

default_notification_level is used to form actual topic name(s) or to set logging level

default_notification_level = INFO

Defined in rpc_notifier, can be comma separated values.

The actual topic names will be %s.%(default_notification_level)s

notification_topics = notifications


resource name(s) that are supported in quota features

quota_items = network,subnet,port

default number of resource allowed per tenant, minus for unlimited

default_quota = -1

number of networks allowed per tenant, and minus means unlimited

quota_network = 10

number of subnets allowed per tenant, and minus means unlimited

quota_subnet = 10

number of ports allowed per tenant, and minus means unlimited

quota_port = 5000 quota_floatingip = 5000

default driver to use for quota checks

quota_driver = quantum.quota.ConfDriver

=========== items for agent management extension =============

Seconds to regard the agent as down.

agent_down_time = 5

=========== end of items for agent management extension =====


Description of the default service type (optional)

description = "default service type"

Enter a service definition line for each advanced service provided

by the default service type.

Each service definition should be in the following format:



If set to true this allows quantum to receive proxied security group calls from nova

proxy_mode = False

[AGENT] root_helper = sudo quantum-rootwrap /etc/quantum ... (more)
