feat: end-to-end validation matrix (all OS × path combinations)

[kristopherjturner]

Overview

Define and execute a comprehensive end-to-end validation matrix that confirms all conversion scenarios work correctly on real hardware. This is the exit gate for the epic.

Scope

• Validation matrix: OS × conversion path × VM configuration
  • Rows: Windows Server 2016, 2019, 2022, Ubuntu 20.04, Ubuntu 22.04, RHEL 8, RHEL 9
  • Columns: Azure Local path, Hyper-V path, single-disk, multi-disk, batch mode
• Automated validation runner that executes the matrix and produces a pass/fail report
• Reference hardware documentation (cluster config, Hyper-V host spec)
• Baseline results committed to tests/validation/results/
• Integration with CI/CD for periodic validation runs

Acceptance Criteria

• All Windows Server 2016/2019/2022 cells pass on Azure Local path
• All Windows Server 2019/2022 cells pass on Hyper-V path
• At least Ubuntu 22.04 passes on both paths
• Batch mode validated with ≥5 VMs in a single run
• Epic [Epic] VM Conversion Toolkit Full Build-Out #5 marked complete only after full matrix passes (required cells)

Dependencies

• Parent Epic: [Epic] VM Conversion Toolkit Full Build-Out #5
• All script issues: feat: script refinement — Azure Local conversion path (01–05 scripts) #6, feat: script refinement — Hyper-V standalone conversion path #7
• Error handling: feat: error handling and staged rollback capability #9
• Logging: feat: shared logging module and Azure Monitor forwarding #10
• CI/CD: infra: CI/CD pipelines (lint, test, release) #11
