Learn how to troubleshoot and resolve virtual machines (VMs) that keep starting after patching Windows Server 2022 Datacenter with Hyper-V role. This guide provides step-by-step solutions for IT professionals.
Virtual machines (VMs) are essential components of modern IT infrastructure, providing flexibility and efficiency in resource management. However, issues can arise, particularly after system updates or patches. This article addresses a common problem where VMs remain in a “Starting” state and provides a comprehensive solution.
Problem Description
After applying patches KB5029250 & KB5029655 to Windows Server 2022 Datacenter with the Hyper-V role, some VMs exhibit persistent “Starting” status. Despite various attempts, including host reboots and patch uninstallation, the issue persists, preventing access to VM settings and requiring VMMS service restarts.
Troubleshooting Steps
To resolve the VM start-up issues, follow these steps:
- Ensure all VM configuration files are intact and uncorrupted.
- Check for any discrepancies in the .xml files associated with the VMs.
- Review the Windows Event Viewer for any related errors or warnings.
- Look for Hyper-V-VMMS and Hyper-V-Worker event logs.
- Confirm that the Integration Services version matches the host’s Hyper-V version.
- Update Integration Services if necessary.
- Assess if the host has sufficient resources (CPU, RAM, storage) to support the VMs.
- Adjust resource allocation to prevent overcommitment.
- Examine virtual network configurations for potential conflicts.
- Reconfigure network settings if required.
- Conduct a clean boot of the host to eliminate interference from third-party services or drivers.
- If available, restore the VMs from a recent backup prior to the patch application.
- If the issue remains unresolved, reach out to Microsoft Support for further assistance.
