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 2: Self-service networks

Configure the Networking components on a compute node.

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, enable VXLAN overlay networks, configure the IP address of the physical network interface that handles overlay networks, and enable layer-2 population:

      [vxlan]
enable_vxlan = True
local_ip = OVERLAY_INTERFACE_IP_ADDRESS
l2_population = True

      Replace OVERLAY_INTERFACE_IP_ADDRESS with the IP address of the underlying physical network interface that handles overlay networks. The example architecture uses the management interface to tunnel traffic to the other nodes. Therefore, replace OVERLAY_INTERFACE_IP_ADDRESS with the management IP address of the compute node. See environment-networking for more information.

    • 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

Return to Networking compute node configuration <neutron-compute-compute>.
