Symptom & Impact

Hyper-V role installation fails on Windows Server 2022 and prevents virtualisation workloads from being deployed or recovered on schedule.

Environment & Reproduction

Issue appears after enabling Hyper-V features when the host is in a pending reboot state or has incomplete servicing operations.

Get-WindowsFeature Hyper-V*
Get-ItemProperty 'HKLM:SOFTWAREMicrosoftWindowsCurrentVersionComponent Based ServicingRebootPending' -ErrorAction SilentlyContinue

Root Cause Analysis

A stale reboot requirement or interrupted CBS transaction blocks feature activation and leaves Hyper-V components partially configured.

Quick Triage

Validate host servicing health and feature state.

Get-WindowsFeature Hyper-V* | Select Name,InstallState
Get-WinEvent -LogName System -MaxEvents 30 | Select TimeCreated,Id,Message

Step-by-Step Diagnosis

Confirm pending reboot markers and servicing logs before remediation.

Solution — Alternative Approaches

Use offline servicing or remove and re-add role payload when corruption persists.

Verification & Acceptance Criteria

Hyper-V services run and VM creation succeeds without feature errors.

Get-Service vmms
Get-VMHost

Rollback Plan

If host instability occurs, remove Hyper-V role and restore pre-change backup.

Uninstall-WindowsFeature Hyper-V -Restart
wbadmin get versions

Prevention & Hardening

Stage cumulative updates before role enablement and enforce reboot checkpoints in maintenance workflows.
