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.
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
How to test
First, with the quantum server and any agents it needs all running, sanity test the configuration using the command line interface: Finally, start the nova services, and create an instance.
