Compute Node

To install and configure the compute node

1. Install the packages:

   # apt-get install openvswitch-switch neutron-plugin-openvswitch-agent

2. Start the OpenvSwitch service:

   # service openvswitch-switch start

3. Create the integration bridge:

   # ovs-vsctl add-br br-int

4. Create the br-eth1 network bridge. All VM communication between the nodes occurs through br-eth1:

   # ovs-vsctl add-br br-eth1
   # ovs-vsctl add-port br-eth1 eth1

5. Edit the OpenStack Networking /etc/neutron/neutron.conf configuration file and add this line:

   rabbit_password = guest
   rabbit_host = controller
   rabbit_password = RABBIT_PASS
   
   [database]
   connection = mysql://neutron:NEUTRON_DBPASS@controller:3306/neutron

6. Edit the /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini file and add these lines:

   [ovs]
   tenant_network_type = vlan
   network_vlan_ranges = physnet1:1:4094
   bridge_mappings = physnet1:br-eth1

7. Restart the OpenvSwitch Neutron plug-in agent:

   # service neutron-plugin-openvswitch-agent restart
