When a partition makes calls to the HvCreateEventLogBuffer hypercall function to create event log buffers, the partition assigns each buffer an event log buffer index that can begin at zero and can end at the maximum number of buffers (which was established at group initialization) minus one. The index is unique within the event log type and is used by both the hypervisor and the guest to identify each individual buffer in a consistent manner. An attempt to create a buffer with an index that exceeds the maximum number of buffers minus one or that matches the index that was assigned to an existing buffer will result in an error.
