Logical Domains 1.3 Administration Guide

Utilization Statistic Definition

The per virtual CPU utilization statistic (UTIL) is shown on the long (-l) option of the ldm list command. The statistic is the percentage of time that the virtual CPU spent executing on behalf of the guest operating system. A virtual CPU is considered to be executing on behalf of the guest operating system except when it has been yielded to the hypervisor. If the guest operating system does not yield virtual CPUs to the hypervisor, the utilization of CPUs in the guest operating system will always show as 100%.

The utilization statistic reported for a logical domain is the average of the virtual CPU utilizations for the virtual CPUs in the domain. A dash (---) in the UTIL column means that the strand is power-managed.
