Who is the course for
- Virtual Machine Administrators interested in moving virtualized workloads
from traditional Hypervisors to OpenShift Virtualization.
- Kubernetes Administrators (Cluster Administrators, Clusters Engineers)
interested in supporting containerized and virtualized workloads in the same
OpenShift cluster.
- Site Reliability Engineers interested in using GitOps and Ansible
Automation to manage Virtual Machines on OpenShift.
What we teach you
- 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.
- Connect VMs to external and extra networks (outside of the Kubernetes pod
and service networks).
- Connect VMs to host storage and external storage.
- Ansible management of VMs.
- Create VMs from VM Templates.
Required skills

Hat OpenShift I: Containers & Kubernetes (DO180) is recommended but not
required.

Course outline
Introduction to OpenShift Virtualization
Describe the
features and use cases of OpenShift Virtualization.
Run and access Virtual Machines
Create, manage, inspect,
and monitor virtual machines in Red Hat OpenShift Virtualization.
Configure Kubernetes network for Virtual
Machines
Configure standard Kubernetes network objects and external
access for VMs and virtual machine-backed applications.
Connect Virtual Machines to external networks
Configure
node networking to connect virtual machines and nodes to networks outside the
cluster.
Configure Kubernetes storage for Virtual Machines
Manage
storage and disks for VMs in Red Hat OpenShift.
Virtual Machine template management
Create and manage
templates to provision virtual machines.
Advanced Virtual Machine management
Snapshot, clone, and
live migrate a virtual machine and initiate node maintenance.
Configure Kubernetes high availability for Virtual
Machines
Configure Kubernetes resources to implement high
availability for virtual machines.
What you need to know
Impact on the Organization
OpenShift Virtualization
allows organizations to realize operational savings by managing virtualized
workloads and containerized workloads together using the same orchestration and
clustering infrastructure provided by Red Hat OpenShift.
Deploying Virtual
Machines (VMs) on OpenShift also eases integration of traditional server-based
applications with more modern cloud-native applications and their supporting
practices such as CI/CD, DevOps, and SRE to take advantage of quicker
time-to-market and other benefits from these practices, without having to first
redesign virtualized workloads as container-native workloads.
Impact on the Individual
IT professionals will learn to
deploy and manage virtualized workloads on OpenShift and manage these workloads
using both traditional ways, such as SSH and Ansible, and also modern DevOps
practices, such as GitOps and CI/CD.
Recommended next course or exam
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: Operating a Production Kubernetes
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.
Linux skills are not required to managing 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.
- Red Hat Linux Automation with Ansible and exam (RH295) for using Ansible
to manage the OS inside a Linux VM.
