Description

Deploy the Quantum virtual network service and configure Nova to use QuantumManager as its NetworkManager. Quantum includes several plugins. The linuxbridge and openvswitch plugins are covered here.

Setup

The installtion of the Quantum packages is done the openstack-demo-install utility. This will also configure a Quantum user with Keystone. The examples below show the usage of OpenvSwitch as the plugin and agent. This can be replaced by any one of the other supperted agents, for example linux bridge.

Enable and start the openvswitch service

$> sudo systemctl enable openvswitch.service
$> sudo systemctl start openvswitch.service

Create the integration bridges (these are used for VM traffic management and layer 3 external networking)

$> sudo ovs-vsctl add-br br-int
$> sudo ovs-vsctl add-br br-ex

Configure quantum-server to use the openvswitch Please note that this will create a database:

$> sudo quantum-server-setup --plugin openvswitch

Enable and start the quantum-server:

$> sudo systemctl enable quantum-server.service
$> sudo systemctl start quantum-server.service

Enable and start the layer 2 agent:

$> sudo systemctl enable quantum-openvswitch-agent.service
$> sudo systemctl start quantum-openvswitch-agent.service

Configure the DHCP service:

$> sudo quantum-dhcp-setup --plugin openvswitch

Enable and start the DHCP agent:

$> sudo systemctl enable quantum-dhcp-agent.service
$> sudo systemctl start quantum-dhcp-agent.service

Configure the L3 service:

$> sudo quantum-l3-setup --plugin openvswitch

Enable and start the L3 agent:

$> sudo systemctl enable quantum-l3-agent.service
$> sudo systemctl start quantum-l3-agent.service

quantum now should be up and ready to go. Check the log files to see if there are any error:

  1. Service - /var/log/quantum/server.log
  2. OpenvSwitch agent - /var/log/quantum/ovs_quantum.log
  3. DHCP agent - /var/log/quantum/dhcp_agent.log
  4. L3 agent - /var/log/quantum/l3_agent.log

How to test

Configuration

Ensure that environment varibales are configured to run the client

$> source keystonerc

Create network and subnet

$> quantum net-create net1
$> quantum subnet-create net1 10.0.0.0/24

Expected Results

  1. After the subnet create the DHCP server should allocate a port to allocate IP addresses to the VMs running on the network. Run quantum port-list to check that a port has been created.
  2. The L2 agent will add the port to the integration bridge. Run sudo ovs-vsctl show. This will show that a tap device for the DHCP agent has been added to the integration bridge. The tap device name will be the first 11 bytes of the port ID.
