| 1 | Networking - FLAT network | ||
| 2 | ========================= | ||
| 3 | |||
| 4 | Description | ||
| 5 | ----------- | ||
| 6 | The flat network will have the VMs share the management network | ||
| 7 | (192.168.7.0/24). The dhcp-agent will provide the VMs addresses | ||
| 8 | within the subnet and within its provisioned range. This type of | ||
| 9 | network will not typically be deployed as everything is accessible by | ||
| 10 | everything else (VMs can access VMs and the compute and controller | ||
| 11 | nodes) | ||
| 12 | |||
| 13 | |||
| 14 | Assumptions | ||
| 15 | ----------- | ||
| 16 | It is assumed you have completed the steps described in | ||
| 17 | README.networking and have provisioned the host vSwitch as well as | ||
| 18 | created the br-eth0 bridges on the controller and compute nodes. | ||
| 19 | |||
| 20 | At this point you should be able to ping 192.168.7.4 from 192.168.7.4 | ||
| 21 | and vise versa. | ||
| 22 | |||
| 23 | You have built your controller image including the cirros image (for | ||
| 24 | which you have already added the image to glance as myFirstImage). | ||
| 25 | |||
| 26 | You have run 'source /etc/nova/openrc' | ||
| 27 | |||
| 28 | Configuration updates | ||
| 29 | --------------------- | ||
| 30 | On the controller and (all) compute nodes you must edit the file | ||
| 31 | /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini | ||
| 32 | |||
| 33 | In the [OVS] section set | ||
| 34 | network_vlan_ranges = ph-eth0:1:1 | ||
| 35 | bridge_mappings = ph-eth0:br-eth0 | ||
| 36 | |||
| 37 | (*** on compute nodes edit local_ip as well [192.168.7.4]***) | ||
| 38 | |||
| 39 | Restart some services to allow these changes to take effect: | ||
| 40 | /etc/init.d/neutron-openvswitch-agent reload | ||
| 41 | (on controller) | ||
| 42 | /etc/init.d/neutron-server reload | ||
| 43 | /etc/init.d/neutron-dhcp-agent reload | ||
| 44 | (on compute) | ||
| 45 | /etc/init.d/nova-compute reload | ||
| 46 | |||
