Guest fails to start with nested virtualization enabled.

    Question

  • I need to enable nested virtualization on a guest running in Hyper-V so that I can use a VMWare Workstation effectively on the guest.

    Server is a Dell PowerEdge R410 with two Intel Xeon E5645 (VT-X with EPT is supported) running Windows Server 2016 Build 14393.  The guest is Windows 10 version 1803, using Hyper-V configuration version 8 generation 2.  

    When nested virtualization is enabled with "Set-VMProcessor -VMName Windows10 -ExposeVirtualizationExtensions $true" the guest fails to start.  It gets to "starting 10%" then returns to the off state.  The system event log displays the error "Windows10 has encountered a fatal error and a memory dump has been generated.  The guest operating system reported that it failed with the following error code: 0x1E.  If the problem persists, contact Product Support for the guest operating system.  (Virtual machine ID 228E40F4-227B-44D5-B7D8-49A070BBE734)".

  • Microsoft supports Hyper-V nested virtualization.  It does not support VMware nested virtualization.

    "I need to enable nested virtualization on a guest running in Hyper-V so that I can use a VMWare Workstation effectively on the guest.

    Your explanation is not very clear.  You said you want to use VMware workstation on a guest.  Then you say your guest is Windows 10 with Hyper-V enabled.  You cannot have both Hyper-V and VMware enabled on the same system.  So you would enable either Hyper-V or VMware, but not both.  But, since you say you are trying to do this in a guest, you can only enable Hyper-V.  VMware is not supported.

  •   As Tim said, nested virtualization is now supported but with strict conditions.

  • Hi,

    Thanks for posting in our forum!

    I don't understand your description very well. As I understand, your guest is win10 and create Hyper-V on it, and now, you also want to use VMware workstation on it, but it failed, if I misunderstood, please let me know.

    I agree with Tim. We can’t create Hyper-V and VMware on the same system. For the detail information, you can refer to following link:

    Hope this information can help you, if you have any question, please feel free to let me know.

    Thanks for your time and have a nice day!

    Best Regards,

    Daniel
