Question

Hi,
I"m experiencing issue with a VM that has previsoulsy been snapshotted. The snap shots have been since deleted via the Hyper V Manager. The snap shots were not applied to the VM. Also no .avhd files have been deleted via Windows Explorer
When I start the VM I get the following error message.

Hi,
Please check whether you receive these error logs: Event ID 3130, 3131, 3320 or 3321.
Check the environment in which the start virtual machine operation was being attempted, including:
access and permissions to the configuration file, memory file and all image files
prior error messages in the event log
available RAM on the system
configuration settings
disk space for the memory file and any expanding virtual hard disks
Once the necessary issues have been rectified, try to start the virtual machine again.
If the problem continues, restart the VMMS 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
