System Center 2012 Virtual Machine Manager Host Parent Partition CPU Utilization

Microsoft.SystemCenter.VirtualMachineManager.2012.HostParentPartitionCPUUtilizationMonitor (UnitMonitor)

Monitors the CPU utilization on the parent partition

Knowledge Base article:

Summary

This monitor tracks the CPU performance of the host. The CPU usage has exceeded the threshold.

Causes

The virtual machines and parent partition workloads running on the host are consuming critical levels of the CPU resources on the host.

Resolutions

Either migrate virtual machines to a different host or reduce parent partition workload CPU consumption. To have Virtual Machine Manger automatically balance host clusters, enable dynamic optimization. For more information about dynamic optimization, see the Virtual Machine Manager documentation.
