Andreas Jaeger 2d44b2b36d Prepare for Sphinx 1.5

The new sphinx version introduces some changes that break build:

* Warns if code cannot be parsed for highlighting. Fix the code so
  that it can be parsed, this includes uncommenting "..." lines.
  Note that not every config file is an ini-file.
  Also, the parser seems to have bugs and cannot parse all files.
  Fix mysql ini file and enable the parameter, see
http://dev.mysql.com/doc/refman/5.7/en/innodb-parameters.html#sysvar_innodb_file_per_table
* :option: works only with declared options, replace useage with
  simple ``.

This change only handles a few files, more to come later.

Networking Option 1: Provider networks

Install and configure the Networking components on the controller node.

Install the components

# apt-get install neutron-server neutron-linuxbridge-agent \
  neutron-dhcp-agent neutron-metadata-agent python-neutronclient

Respond to prompts for database management, Identity service credentials, service endpoint registration, and message queue credentials.

Select the ML2 plug-in:

Note

Selecting the ML2 plug-in also populates the core_plugin option in the /etc/neutron/neutron.conf file with the appropriate values (in this case, it is set to the value ml2).

Configure the server component

Edit the /etc/neutron/neutron.conf file and complete the following actions:

In the [DEFAULT] section, disable additional plug-ins:
```
[DEFAULT]
# ...
service_plugins =
```

In the [DEFAULT] and [nova] sections, configure Networking to notify Compute of network topology changes:

[DEFAULT]
# ...
notify_nova_on_port_status_changes = True
notify_nova_on_port_data_changes = True

[nova]
# ...
auth_url = http://controller:35357
auth_type = password
project_domain_name = default
user_domain_name = default
region_name = RegionOne
project_name = service
username = nova
password = NOVA_PASS

Replace NOVA_PASS with the password you chose for the nova user in the Identity service.

Configure the Modular Layer 2 (ML2) plug-in

The ML2 plug-in uses the Linux bridge mechanism to build layer-2 (bridging and switching) virtual networking infrastructure for instances.

Edit the /etc/neutron/plugins/ml2/ml2_conf.ini file and complete the following actions:
- In the [ml2] section, enable flat and VLAN networks:
```
[ml2]
# ...
type_drivers = flat,vlan
```
- In the [ml2] section, disable self-service networks:
```
[ml2]
# ...
tenant_network_types =
```
- In the [ml2] section, enable the Linux bridge mechanism:
```
[ml2]
# ...
mechanism_drivers = linuxbridge
```
  Warning
  
  After you configure the ML2 plug-in, removing values in the type_drivers option can lead to database inconsistency.
- In the [ml2] section, enable the port security extension driver:
```
[ml2]
# ...
extension_drivers = port_security
```
- In the [ml2_type_flat] section, configure the provider virtual network as a flat network:
```
[ml2_type_flat]
# ...
flat_networks = provider
```
- In the [securitygroup] section, enable ipset to increase efficiency of security group rules:
```
[securitygroup]
# ...
enable_ipset = True
```

Configure the Linux bridge agent

The Linux bridge agent builds layer-2 (bridging and switching) virtual networking infrastructure for instances and handles security groups.

Edit the /etc/neutron/plugins/ml2/linuxbridge_agent.ini file and complete the following actions:
- In the [linux_bridge] section, map the provider virtual network to the provider physical network interface:
```
[linux_bridge]
physical_interface_mappings = provider:PROVIDER_INTERFACE_NAME
```
  Replace PROVIDER_INTERFACE_NAME with the name of the underlying provider physical network interface. See environment-networking for more information.
- In the [vxlan] section, disable VXLAN overlay networks:
```
[vxlan]
enable_vxlan = False
```
- In the [securitygroup] section, enable security groups and configure the Linux bridge iptables firewall driver:
```
[securitygroup]
# ...
enable_security_group = True
firewall_driver = neutron.agent.linux.iptables_firewall.IptablesFirewallDriver
```

Configure the DHCP agent

The DHCP agent provides DHCP services for virtual networks.

Edit the /etc/neutron/dhcp_agent.ini file and complete the following actions:
- In the [DEFAULT] section, configure the Linux bridge interface driver, Dnsmasq DHCP driver, and enable isolated metadata so instances on provider networks can access metadata over the network:
```
[DEFAULT]
# ...
interface_driver = linuxbridge
dhcp_driver = neutron.agent.linux.dhcp.Dnsmasq
enable_isolated_metadata = True
```

Return to Networking controller node configuration <neutron-controller-metadata-agent>.
