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 Red Hat Enterprise Linux 7.4 Binary DVD image that will be used to create the guest templates, as file, in /iso-images.
Make sure to use the Binary DVD image, not the Boot ISO or KVM Guest images.
cp /tmp/rhel-server-7.4-x86_64-dvd.iso /iso-images/
3. Create a partition-based storage pool to maintain storage for the virtualization guests, as described in this procedure. It is conventionally named "main-storage-pool". Make sure it has enough space available to accommodate the OpenShift environment's storage needs:
virsh # pool-dumpxml main-storage-pool
<pool type='fs'>
<name>main-storage-pool</name>
<uuid>5e3b81b6-a596-404f-a091-ef738dc21df5</uuid>
<capacity unit='bytes'>938496245760</capacity>
<allocation unit='bytes'>9520472064</allocation>
<available unit='bytes'>928975773696</available>
