Event InformationAccording to Microsoft:

Cause :

This event is logged when Hyper-V Virtual Machine Management service is being shut down while some virtual machines are runnings.

Resolution :

Turn off virtual machines

Vmms.exe (by default in the %windows%\system32 directory) is the service that uses the Msvm_VirtualSystemManagementService WMI object to perform Virtual System Management related operations in Hyper-V and the Hyper-V Manager. This error means the vmms was shutdown through the Service Control Manager (SCM) and all the virtual machines on the virtualization server (also called a host) may not have been not turned off.

Restart the Virtual Machine Management Service (VMMS), then turn Off any virtual machines that are still turned on.

To restart VMMS using the Service Manager:
  1. In the Hyper-V Manager click the server on which you want to stop the service, then click Action , then click Stop Service.
  2. Click Action , then click Start Service .
To restart the VMMS service using the command prompt:
  • On the computer that has the stopped service, open a command prompt as local administrator and type the following:
    net stop nvpswmi
    If the service is not running, you will see the error "The Hyper-V Networking Management service is not started."
    net start nvspwmi
  • If the service start starts you will see the message "The Hyper-V Networking Management service was start successfully."

    To restart VMMS using PowerShell.
    1. On the computer that has the stopped service, open a command prompt as local administrator and type the following:
    C:\PS>restart-service vmms

    Verify :

    Check that the VMMS service is in the running state in the Service Control Manager and that the failed operation now succeeds.
