Appendix C. Red Hat Virtualization User Interface Plugins
C.1. Red Hat Virtualization User Interface Plug-ins
Red Hat Virtualization supports plug-ins that expose non-standard features. This makes it easier to use the Red Hat Virtualization Administration Portal to integrate with other systems. Each interface plug-in represents a set of user interface extensions that can be packaged and distributed for use with Red Hat Virtualization.
At key events during runtime, the Administration Portal invokes individual plug-ins via event handler functions representing Administration-Portal-to-plug-in communication. Although the Administration Portal supports multiple event-handler functions, a plug-in declares functions which are of interest only to its implementation. Each plug-in must register relevant event handler functions as part of the plug-in bootstrap sequence before the plug-in is put to use by the administration portal.
