DO316 – Managing Virtual Machines with Red Hat OpenShift Virtualization — Lesson 1: OpenShift Virtualization Architecture, Operator, VM Objects, and Lifecycle

Learning Objectives

• Explain the structures, services, data, settings, roles, and dependencies governing KubeVirt architecture and OpenShift Virtualization operator.
• Implement and validate VM objects, VM lifecycle, and console and CLI using reviewable evidence.
• Evaluate the condition where the observed result differs from the approved configuration because a prerequisite, permission, dependency, or sequence was missed and select a proportionate corrective response.

Detailed Topics

• KubeVirt architecture applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• OpenShift Virtualization operator applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• VM objects applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• VM lifecycle applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• console and CLI applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.

Instructor Demonstration

The instructor traces a virtualization team onboarding traditional virtual machines to a shared OpenShift platform. The walkthrough connects navigation, commands, configuration logic, system messages, and evidence captured in the OpenShift Virtualization operating model, VM deployment records, migration plan, and recovery checklist. It also tests the exception where the observed result differs from the approved configuration because a prerequisite, permission, dependency, or sequence was missed.

Hands-On Exercise

Complete a controlled Red Hat exercise covering OpenShift Virtualization Architecture, Operator, VM Objects, and Lifecycle and preserve the verified result in the OpenShift Virtualization operating model, VM deployment records, migration plan, and recovery checklist.

1. Confirm scope, prerequisites, versions, identities, dependencies, and acceptance criteria.
2. Execute the workflow while recording commands, settings, outputs, events, and system messages.
3. Test normal behavior, one boundary condition, and the stated exception.
4. Document corrections, evidence, ownership, retest criteria, rollback, and handover actions.

Scenario Analysis

• Identify which object, service, policy, setting, or sequence most strongly influences KubeVirt architecture.
• Compare two defensible responses and explain technical, security, operational, and support trade-offs.
• Determine how the OpenShift Virtualization operating model, VM deployment records, migration plan, and recovery checklist should be approved, retained, retested, and updated.

Troubleshooting Guidance

Start where expected behavior first differs from the observed result. Check prerequisites, identity, configuration order, version compatibility, connectivity, status, resource limits, and evidence separately. Treat “the observed result differs from the approved configuration because a prerequisite, permission, dependency, or sequence was missed” as a hypothesis until commands, logs, settings, and retest outcomes confirm the cause.

Validation Checklist

• Required platform components, identities, permissions, settings, and dependencies are present.
• The OpenShift Virtualization operating model, VM deployment records, migration plan, and recovery checklist connects each conclusion to objective, reviewable evidence.
• Normal processing, a boundary condition, dependency behavior, and the stated exception were tested.
• Corrections, ownership, retest criteria, rollback, documentation, and operational handover are complete.

Lesson Outcome

Learners can apply OpenShift Virtualization Architecture, Operator, VM Objects, and Lifecycle, explain the resulting platform behavior, and defend the outcome through the OpenShift Virtualization operating model, VM deployment records, migration plan, and recovery checklist.
