RH018 – Virtualization and Infrastructure Migration Technical Overview — Lesson 1: Virtualization Landscape, KVM, OpenShift Virtualization, and Platform Concepts

Learning Objectives

• Explain the structures, services, data, settings, roles, and dependencies governing virtualization landscape and KVM.
• Implement and validate KubeVirt, OpenShift Virtualization, and platform comparison 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

• virtualization landscape applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• KVM applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• KubeVirt applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• OpenShift Virtualization applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.
• platform comparison applied to the course scenario, expected platform behavior, dependencies, controls, and evidence.

Instructor Demonstration

The instructor traces an architecture team evaluating how to modernize a mixed virtualization estate and migrate workloads with controlled risk. The walkthrough connects navigation, commands, configuration logic, system messages, and evidence captured in the virtualization assessment, migration option analysis, risk register, and phased modernization roadmap. 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 Virtualization Landscape, KVM, OpenShift Virtualization, and Platform Concepts and preserve the verified result in the virtualization assessment, migration option analysis, risk register, and phased modernization roadmap.

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 virtualization landscape.
• Compare two defensible responses and explain technical, security, operational, and support trade-offs.
• Determine how the virtualization assessment, migration option analysis, risk register, and phased modernization roadmap 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 virtualization assessment, migration option analysis, risk register, and phased modernization roadmap 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 Virtualization Landscape, KVM, OpenShift Virtualization, and Platform Concepts, explain the resulting platform behavior, and defend the outcome through the virtualization assessment, migration option analysis, risk register, and phased modernization roadmap.
