DO016 – Red Hat OpenShift Virtualization Technical Overview — Lesson 1: OpenShift Virtualization Architecture, KubeVirt, Operator, and Use Cases

Learning Objectives

• Explain the architecture, purpose, dependencies, and expected behavior of OpenShift Virtualization architecture, KubeVirt, and operator.
• Apply platform integration and use cases 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.
• KubeVirt: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• operator: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• platform integration: apply the concept to the course scenario, identify dependencies and controls, and record objective evidence of the result.
• use cases: 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, kubevirt, operator, and use cases 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, KubeVirt, Operator, and Use Cases and add the verified result to the virtualization capability assessment, VM architecture map, migration considerations, and next-step roadmap.

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 platform integration and explain the security, reliability, performance, and support trade-offs.
• Decide what evidence must be retained in the virtualization capability assessment, VM architecture map, migration considerations, and next-step roadmap 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 capability assessment, VM architecture map, migration considerations, and next-step roadmap 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, KubeVirt, Operator, and Use Cases, explain the observed platform behavior, and support the result with a reviewable virtualization capability assessment, VM architecture map, migration considerations, and next-step roadmap.
