Objectives

• 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 for this course

• Take our free assessment to gauge whether this offering is the best fit for your skills
• 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.

Audience

• 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

Outline

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.

Running and Accessing Virtual Machines

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

Configuring Kubernetes Networking for Virtual Machines

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

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.

Configuring Storage for Virtual Machines

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

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.

Replicating Virtual Machines by Using Instance Types, Templates, and Clones

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

Advanced Virtual Machine Management

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

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.
