Number Of CPU CORE from cpuinfo File Available for DOM0 (Doc ID 1682786.1)

Last updated on SEPTEMBER 17, 2017

Applies to:

Oracle VM - Version 3.0.1 to 3.2.8 [Release OVM30 to OVM32]
Linux x86-64

Goal

Major distinctions between xen hypervisor and dom0.

http://wiki.xen.org/wiki/Hypervisor

http://wiki.xen.org/wiki/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"?
