to do.

Quantum plugin specific files

Quantum plugins require plugin specific behavior. The files under the directory, lib/quantum_plugins/, will be used when their service is enabled. Each plugin has lib/quantum_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/quantum calls the following functions when the $Q_PLUGIN is enabled

  • quantum_plugin_create_nova_conf : set NOVA_VIF_DRIVER and optionally set options in nova_conf e.g. NOVA_VIF_DRIVER=${NOVA_VIF_DRIVER:-"nova.virt.libvirt.vif.LibvirtGenericVIFDriver"}
  • quantum_plugin_install_agent_packages : install packages that is specific to plugin agent e.g. install_package bridge-utils
  • quantum_plugin_configure_common : set plugin-specific variables, Q_PLUGIN_CONF_PATH, Q_PLUGIN_CONF_FILENAME, Q_DB_NAME, Q_PLUGIN_CLASS
  • quantum_plugin_configure_debug_command
