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/
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":
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> <source> <device path='/dev/sda7'/> <format type='auto'/> </source> <target> <path>/main-storage-pool</path> <permissions> <mode>0755</mode> <owner>0</owner> <group>0</group> <label>system_u:object_r:unlabeled_t:s0</label> </permissions> </target> </pool>
