Nested Windows Hyper-V Server 2012 R2 on VMware vSphere ESXi 6

As I still have a preference for VMware and with the annoying inconvenience still fresh in my mind from the previous two posts on managing Windows Server & Hyper-V outside a domain (within  a workgroup) I decided to deploy Hyper-V as a nested VM within my VMware environment. Though for Hyper-V role to be installed a few tweaks have to be applied to the VM(s) in question.

Step 1 – Configure CPU/MMU Virtualisation

Within vSphere go to the VM properties, Options tab and under CPU/MMU Virtualization option select Use Intel VTx/AMD-V for instruction set virtualization and Intel EPT/AMD RVI or MMU virtualization

Windows vSphere C# Client
vSphere Web Client

Step 2 – Add VMX Attributes

  1. Shutdown the VM
  2. Browse to the datastore which hosts the VMX file of the VM in question
  3. Download it locally
  4. Open the VMX file in your favorite text editor (Notepad or Notepad++) and add the end of it:
hypervisor.cpuid.v0 = "FALSE"
vhv.enable= "TRUE"

Result

You are now able to proceed in adding the Hyper-V role:

    Thank you for the post!

    But I can’t get it working on ESXi 6.0 Update 2 (build 3620759).

    When I edit the .vmx file and upload it back to datastore, ESXi doesn’t recognize it as a valid virtual machine configuration file. I can’t register a VM from it. And even if I just replace the .vmx file for an existing VM it doesn’t power on and shows the error of configuration file:

    “An error was received from the ESX host while powering on VM HV5 (Hyper-V).
    Unable to load configuration file ‘/vmfs/volumes/575552a9-49a8011f-e4cc-7054d28f994f/HV5 (Hyper-V)/HV5 (Hyper-V).vmx’.”

    How can that issue be resolved?
    Thanks in advance.

        Check the box next to “Expose hardware-assisted virtualization to the guest operating system.” And add to the .vmx file this string hypervisor.cpuid.v0 = “FALSE”

        hi Corin, I’ve figured it out:

        On ESXi 6.0 Update 2 (build 3620759) only one line in the .vmx configuration file should be added:

        hypervisor.cpuid.v0 = “FALSE”

        And then it worked perfectly for me! 🙂 sucessfully created a virtual Hyper-V cluster, and there is almost no performance looses.

    Great post, it works for ESXi 6.0 U2; one addition you need to reload the configuration files at the end of this process

    vim-cmd vmsvc/getallvms
    vim-cmd vmsvc/reload n (n is the vm id, for example 4)

    These commands can be run from the ESXi shell through SSH

    ..i make @ changes, but can’t activate Hyper-V Serverrole:
    Message:
    can not be installed because the processor does not have the necessary virtualization capabilities
