Matt Riedemann 925c256cd4 Remove NOVA_VIF_DRIVER variable
Commit 7561c8ded211d53e8745d1420a73b82bd0fc35cf removed the
libvirt.vif_driver option from Nova in Juno so we should remove the
variable from devstack since it's useless / confusing.

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.

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
