+
+ - Adding a user account
+ - Modifying user account
+ - Deleting a user account
+ - login event
+ - logout event
+ - IP whitelisting update
+ - IP blacklisting update
+
+* VNFC Creation
+
+ - The instantiation of a newly-defined VNFC
+ - The instantiation of a VNFC with pre-configured state
+ - The cloning of an existing VNFC
+
+* VNFC Deletion
+
+ - The deletion of VNFC and of all of its instances (e.g. snapshots, backups, archives, cloned images)
+
+* Software management
+
+ - patching e.g. opreating system, drivers, VM components
+ - dynamic updates to the configuration e.g. DNS, DHCP
+ - application software updates

+
+* Other VNFC Operational State Changes
+
+ - Hibernation, sleep, resumption, abort, restore, suspension
