Overview

This procedure describes preparatory operations required by the installation of an OpenShift environment on a KVM virtualization host. None of these operations are OpenShift-specific, but they are necessary if OpenShift and support nodes are to be deployed in a KVM virtualization environment.

Procedure

1. Create a directory-based storage pool to maintain the ISO images used in the installation, as described in this procedure. The conventional name of the pool is "iso-images": 

virsh # pool-info iso-images
Name:           iso-images
UUID:           e91bb163-c4be-4c1a-9212-70903e407a1c
State:          running
Persistent:     yes
Autostart:      yes
Capacity:       49.98 GiB
Allocation:     11.63 GiB
Available:      38.35 GiB

2. Stage the Red Hat Enterprise Linux 7.4 Boot ISO image that will be used to create the guest templates, as file, in /iso-images 

cp /tmp/rhel-server-7.4-x86_64-boot.iso /iso-images/
