DO156: Red Hat OpenShift Virtualization Administration I — Lesson 1: OpenShift Virtualization Architecture, Operator, Resources, and Administration Interfaces

Learning Objectives

• Explain the architecture, purpose, dependencies, and expected behavior of OpenShift Virtualization architecture, operator installation, and KubeVirt resources.
• Apply web console and command-line interfaces while preserving reviewable technical evidence.
• Recognize and correct the condition where an unstated prerequisite or ownership gap causes the initial design to be incomplete.

Detailed Topics

• OpenShift Virtualization architecture: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• operator installation: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• KubeVirt resources: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• web console: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• command-line interfaces: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.

Instructor Demonstration

The instructor demonstrates openshift virtualization architecture, operator, resources, and administration interfaces by tracing architecture, commands, configuration, system messages, and evidence. The walkthrough tests how an unstated prerequisite or ownership gap causes the initial design to be incomplete and explains how to isolate the cause without masking related issues.

Hands-On Exercise

Establish a controlled baseline for OpenShift Virtualization Architecture, Operator, Resources, and Administration Interfaces and add the verified result to the virtualization operator baseline, VM build records, networking and storage tests, and support checklist.

1. Confirm scope, versions, access, dependencies, assumptions, and acceptance criteria.
2. Perform the workflow while recording commands, configuration, output, events, and decisions.
3. Test the normal path and one course-specific exception or boundary condition.
4. Retest the correction and document rollback, ownership, and follow-up actions.

Scenario Analysis

• Identify which dependency most strongly influences OpenShift Virtualization architecture in the stated scenario.
• Compare two approaches for web console and explain the security, reliability, performance, and support trade-offs.
• Decide what evidence must be retained in the virtualization operator baseline, VM build records, networking and storage tests, and support checklist before operational acceptance.

Troubleshooting Guidance

Begin with the first observable difference from the expected result. Check architecture, scope, identities, prerequisites, and starting conditions separately, then correlate logs, events, commands, metrics, and configuration history. Treat the assumption that an unstated prerequisite or ownership gap causes the initial design to be incomplete as a hypothesis until a reproducible retest confirms the cause.

Validation Checklist

• The required architecture, scope, identities, prerequisites, and starting conditions were checked and recorded.
• The normal path and a course-specific exception were tested.
• The virtualization operator baseline, VM build records, networking and storage tests, and support checklist links conclusions to commands, configuration, logs, metrics, or other objective evidence.
• Corrective actions, rollback, ownership, and handover notes are complete.

Lesson Outcome

Learners can apply OpenShift Virtualization Architecture, Operator, Resources, and Administration Interfaces, explain the observed platform behavior, and support the result with a reviewable virtualization operator baseline, VM build records, networking and storage tests, and support checklist.
