Red Hat Certified Specialist in OpenShift Virtualization

Overview

Create and manage virtual machines on OpenShift using the Red Hat OpenShift Virtualization operator

Managing Virtual Machines with OpenShift Virtualization teaches the essential skills required to create and manage virtual machines (VM) on OpenShift using the Red Hat OpenShift Virtualization operator. This course does not require previous knowledge of containers and Kubernetes.

This course provides:

• Skills required to create, access, and manage VMs on OpenShift clusters

• Skills required to control usage and access of cpu, memory, storage, and networking resources from VMs using the same Kubernetes features that would also control usage and access to these resources for containers

• Sample architectures to manage High Availability (HA) of VMs using standard Kubernetes features and extensions from OpenShift Virtualization

• Strategies to connect VMs on OpenShift to data center services outside of their OpenShift cluster, such as storage and databases

• Strategies to migrate VMs from compatible hypervisors to OpenShift Virtualization by using the Migration Toolkit for Virtualization operator

Audience Profile

Virtual Machine Administrators who want to virtualize workloads from traditional Hypervisors to OpenShift Virtualization

Platform Engineers, Cloud Administrators, and System Administrators who want to support virtualized workloads, either independently from or in the same OpenShift cluster as containerized workloads

Prerequisites

• Red Hat OpenShift Administration I: Operating a Production Cluster (DO180) is recommended but not required

• Linux skills are not required to manage OpenShift clusters and OpenShift Virtualization but managing individual Linux VMs requires Linux sysadmin skills provided by:

  • Red Hat System Administration I (RH124) and Red Hat System Administration II (RH134) for managing the OS inside a Linux VM.

At Course Completion

Create VMs from installation media and disk images

Access text and graphical consoles of a VM

Connect to VMs using Kubernetes networking (services, ingress, and routes)

Provision storage to VMs using Kubernetes storage (PVC, PV, and storage classes)

Start, pause, and stop VMs

Clone and snapshot VMs

Create and seal golden VM images

Connect VMs to external and extra networks (outside of the Kubernetes pod and service networks)

Provision load balancer services for VMs and then use the services to enable SSH access to VMs

Connect VMs to host storage and external storage

Create VMs from predefined and custom VM Templates and InstanceTypes

Migrate VMs from compatible hypervisors

Back up and restore VMs by using OADP and command-line tools

Course Outline

Module 1: Red Hat OpenShift Virtualization

Distinguish Red Hat OpenShift Virtualization from container technologies and from traditional virtual machine technologies. Describe the features and use cases of OpenShift Virtualization. Deploy the OpenShift Virtualization operator in an existing Red Hat OpenShift environment.

Module 2: Running and Accessing Virtual Machines

Create, manage, inspect, and monitor virtual machines in Red Hat OpenShift Virtualization.

Module 3: Configuring Kubernetes Networking for Virtual Machines

Configure standard Kubernetes network objects and external access for VMs and virtual machine-backed applications.

Module 4: Connecting Virtual Machines to External Networks

Configure node networking to connect virtual machines and nodes to networks outside of the cluster by using Multus CNI plug-ins and the NMState operator.

Module 5: Configuring Storage for Virtual Machines

Manage storage and disks for virtual machines in Red Hat OpenShift by using Kubernetes.

Module 6: Create and Restore Backups of Virtual Machines

Create virtual machine snapshots and back up virtual machine components individually and by using the OpenShift APIs for Data Protection (OADP) operator.

Module 7: Replicating Virtual Machines by Using Instance Types, Templates, and Clones

Create and manage clones, templates, and instance types to provision virtual machines.

Module 8: Advanced Virtual Machine Management

Import, control the placement of, monitor the health of, and live migrate virtual machines.

Module 9: Configuring Kubernetes High Availability for Virtual Machines

Implement high availability virtual machines that are resilient to failures, planned maintenance, and cluster upgrades by configuring Kubernetes resources.
