Hi,

I have a Hyper-V server on my DR site and a Veeam Backup server. May I know do I need to license the Hyper-V OSE VM again whenever I restore the VM to the DR server?
The Hyper-V server is Windows Server 2016 Standard version and only allows 2 VM. The production VM has already been licensed.

Kindly advice

Thank You

    Hi @DEREK YEO TAT KAI ,

    Virtual machines do not have licenses, the licenses are assigned to the physical hosts. Licenses assigned to the physical hosts grant rights to two (Standard for two physical CPUs) or unlimited (Datacenter for two physical CPUs) virtual operating system environments running Windows Server.

    Two common scenarios for higher availability and dynamic data centers involve:

    • Running the same workload simultaneously on two servers, or Only run the workload during maintenance.
    • Running a workload on a primary server and periodically moving it to a second server due to a failure, load balancing, patching, or planned downtime.

    In both scenarios, regardless of whether the workloads are running in physical or virtual OSEs, each server must have the appropriate number of licenses assigned to it prior to the workload running on it.

    The above information can be found from here:
    Licensing Windows Server for use with virtualization

    Hello DEREKYEO,

    Unfortunately, yes. It is normally necessary to fulfill the activation process once restored.

    But, In this case because you are using Hyper-V and the benefit of AVMA, it can work automatically if you have the AVMA keys preconfigured in the VMs prior to their backup.

    AVMA Reference: https://learn.microsoft.com/en-us/windows-server/get-started/automatic-vm-activation
