Managing Virtual Machines with Red Hat OpenShift Virtualization (DO316)

DO316 - 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.

Following course completion, hands-on lab access will remain available for up to 45 days for any live course that includes a virtual environment.

Who Should Attend?

This course is intended for

  • 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.

What You'll Learn

After completing this course, learners should be able to:

  • 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 .

Prerequisites

Recommended:

  • Red Hat OpenShift Administration I: Operating a Production Cluster (DO180)
    • 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.
    • For candidates that have not earned an RHCSA or equivalent, confirmation of the correct skill set knowledge can be obtained by passing the online skills assessment at Red Hat Skills Assessment

Follow-On Courses

VM Administrators using OpenShift Virtualization require deeper Kubernetes and OpenShift skills than provided by DO316, even if they do not intend to manage containerized, cloud-native applications, and these skills are provided by existing OpenShift Administration courses:

  • Red Hat OpenShift Administration II: Configuring a Production Cluster (DO280) is also a recommended follow-up course for security and resource management of OpenShift projects.
  • Red Hat OpenShift Administration III: Scaling Kubernetes Deployments in the Enterprise (DO380)
  • And Enterprise Kubernetes Storage with Red Hat OpenShift Data Foundation (DO370) are recommended follow-up courses for node, storage, and security management of OpenShift clusters.
  • Red Hat OpenShift Installation Lab (DO322) is a recommended follow-up course for installing and configuring OpenShift clusters.
