Resolve

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:

1. 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."

3. On the command prompt type the following command to start the nvpswmi service

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.
