Optimal Multi-Core Health Monitor Architecture

A multi-core processor system and a method of operating the system allocates fault queues in a shared system memory for each virtual machine of a partitioned guest operating system running on a core or partition of the processor system. Health monitors of the partitioned guest operating system log faults in the fault queue corresponding to the appropriate virtual machine. The health monitors may take additional action in response to warning-level or virtual machine-level faults. A health monitor of the multi-core processor resource then polls each fault queue, as well as the partition-level and module-level event logs maintained by the module operating system, for available faults and logs all faults in a single nonvolatile event log of the multi-core processor resource.
