Abstract
A hypervisor includes methods to receive an event log from an event source. The event log includes a notify of every partition (NEP) flag. The status of the NEP flag indicates whether the event log is to be sent to all partitions. If the NEP flag is set to a value indicating that the event log is not to be sent to all partitions, then for each partition in a set of active partitions, the hypervisor reads a platform event monitor (PEM) flag for the partition. If the platform event monitor flag is set to a value indicating the partition is to receive the event, the hypervisor passes the event log to an event service for the partition.
