We have a set +of listener plugins which listens for fencing requests for virtual +machines. + +These plugins are assigned callbacks which are entry functions in to +the backend plugins. The backend plugins perform the actual fencing +request. + +In the middle, we have only enough code to provide basic integration +functions between the listener and backend plugins. This includes a +very simple confiugration plugin which we pass to each of the plugins. + +Because we are passing function pointers in to the plugins themselves +for configuration (rather than having the plugins call an API directly, +for example), we are able to swap out the configuration subsystem for +other, more full-featured configuration systems, such as libccs. |
