How to determine if a few selected CPUs are overloaded while the others are idle when pinning CPUs to Virtual Machines (Doc ID 2095273.1)

Last updated on MAY 26, 2021

Applies to:

Oracle VM - Version 3.3.3 and later
Oracle Cloud Infrastructure - Version N/A and later
Linux x86-64

Goal

On Oracle VM 3.X.X, when pinning vCPUs to particular virtual machines, e.g. when configuring hard partitioning, one can want to monitor the hypervisor server (VM Server, dom0) to determine if some CPUs are not used at all, e.g. in case there is the need to provision new Virtual Machines on this VM Server.

Note : This solution doesn't apply if there are no CPU pinning configured as the load should be spread across all CPUs / vCPUs.
