Hyper-V cannot connect Virtual Machine Management Service.

Question

Hello,

Hyper-v suddenly cannot connect Virtual Machine Management Service even with the following services running.

• Hyper-V Host Compute Service
• Hyper-V Machine Management.

I also added my user account to the group hyper-v administrator.

However, the hyper-v window keeps stacking on the following message, and the screen won't change.

Would you please tell me how to resolve this issue?

Hello Kashihara, Hiroki,

Thank you for posting in Q&A forum.

If Hyper-V is suddenly unable to connect to the Virtual Machine Management Service (VMMS)，here are several steps you can take to troubleshoot:

1. Restart the Hyper-V Virtual Machine Management Service:
2. Check for Error Messages in Event Viewer:

Check for any relevant error messages that might indicate the underlying issue with the Virtual Machine Management Service.

3. Verify the Hyper-V Services:

Make sure all Hyper-V related services are running properly:

Hyper-V Virtual Machine Management

Hyper-V Host Compute Service

Hyper-V Networking Management Service

If any of these services are stopped, start them manually and ensure they are set to Automatic.

4. Check Hyper-V Requirements and Role:

Ensure that the Hyper-V role is still enabled. Sometimes after updates or hardware changes, the Hyper-V role can become misconfigured.

You can also check this via PowerShell:

Get-WindowsFeature -Name Hyper-V

If it's disabled or missing, re-enable the Hyper-V role:

Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-All

5. Check Hyper-V Network Configuration:

Sometimes, network configuration issues or virtual switches can cause the Virtual Machine Management Service to fail. If you've recently changed your network settings, it may cause Hyper-V issues. You can try removing and re-adding virtual switches from the Virtual Switch Manager.

6. Reboot the Host Machine:

If restarting services doesn't work, a full reboot of the host machine can sometimes resolve issues with the Virtual Machine Management Service, especially after system updates.

 

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.
