Sean M. Collins 75a6454097 neutron: Wait until ovs-vswitchd creates the bridge
Seeing a race condition where lib/neutron code tries to
set the MTU on br-ex before it exists.

Thanks to some good grepping by sdague, it appears that the difference
between lib/neutron and lib/neutron-legacy is that the initial bridge
being created is br-int while in lib/neutron the initial bridge
created is br-ex, which means there must be some kind of warm-up that
occurs between the first bridge that is created by ovs-vswitchd and the
second, and the second one created is much faster.

So instead, let's just wait for the bridge to be created successfully.

Neutron plugin specific files

Neutron plugins require plugin specific behavior. The files under the directory, lib/neutron_plugins/, will be used when their service is enabled. Each plugin has lib/neutron_plugins/$Q_PLUGIN and define the following functions. Plugin specific configuration variables should be in this file.

  • filename: $Q_PLUGIN
    • The corresponding file name MUST be the same to plugin name $Q_PLUGIN. Plugin specific configuration variables should be in this file.

functions

lib/neutron-legacy calls the following functions when the $Q_PLUGIN is enabled

  • neutron_plugin_create_nova_conf : optionally set options in nova_conf
  • neutron_plugin_install_agent_packages : install packages that is specific to plugin agent e.g. install_package bridge-utils
  • neutron_plugin_configure_common : set plugin-specific variables, Q_PLUGIN_CONF_PATH, Q_PLUGIN_CONF_FILENAME, Q_PLUGIN_CLASS
  • neutron_plugin_configure_debug_command
  • neutron_plugin_configure_dhcp_agent
  • neutron_plugin_configure_l3_agent
  • neutron_plugin_configure_plugin_agent
  • neutron_plugin_configure_service
  • neutron_plugin_setup_interface_driver
  • has_neutron_plugin_security_group: return 0 if the plugin support neutron security group otherwise return 1
  • neutron_plugin_check_adv_test_requirements: return 0 if requirements are satisfied otherwise return 1
