Hyper-V Management Service Fails to start RRS feed

  • General discussion

  • Hi,

    I have a windows server 2012 standard with Hyper-V role configured. This configuration is being backed up by Veeam backup and replication. I started getting errors from Veeam backup couple of days ago. I was also told by Veeam support before that such issues would be fixed by restarting the Hyper-V Manager service on the hyper-v host. 

    So I stoped the service and then tried to start it. the service did not start. I get below error:

    Windows Could not start the Hyper-V Virtual Machine Management Service on Local Computer. 

    Error 0x80040154: Class not registered

    Event viewer does not give much details about the error in starting the service. All I get from Event viewer is:

    I have checked WMI service and it is running. Any thoughts on this and how to solve this issue?
