Last updated on MAY 26, 2021

Applies to:

Oracle VM - Version 3.0.1 to 3.4.4 [Release OVM30 to OVM34]
Oracle Cloud Infrastructure - Version N/A and later
Linux x86-64


Major distinctions between xen hypervisor and dom0.

The two possible major confusion here is how to check hypervisor and dom0's memory and CPU info.

EXAMPLE:Monitoring tool is confused around DOM0 available CPU/CORE:


4 processors (physical id 0-3) with 8 cores (core id 0-3 y 8-11) and hyperthreading (siblings = 2 * cpu core, and flag ht). So the total number of logical cpus is 64 (info from /proc/cpuinfo).

How could interpret " cpu cores : 1"?
