Will the running VMs be impacted if I restart the "Hyper-V Virtual Machine Management" service?

    Question

  • The host OS is Windows Server 2008 R2. Because of some particular reason, I have to restart the Hyper-V Virtual Machine Management service on the host. I don't know if this will impact the VMs (guest OS). This is the production environment. I don't have a lab environment to test. Thanks!

  • Hi!

    Restarting or stopping the Hyper-V Virtual Machine Management service should not affect running VM's, only your ability to manage them such as through Hyper-V manager.

  • Like Andrews said, your VMs are not going to be affected by stopping/restarting the Hyper-V Virtual Machine Management service. Durring that time those VMs will dissapear from the Hyper-V Management console, and you won't be able to manage them.

  • Hi,

    If you restart this service, your virtual machines will be unavailable for the time of restart. 

    Why do yo have to do this operation ?
