    How To Create Nested Virtualization Using Hyper-V In The Guest?

    CuiZinieR Novice




      I try to do nested virtualization with VMware Player v7 and Windows Server 2012 R2 as the guest but fail to install the Hyper-V role.



      According to this VMware document, it's possible to run a VM within a VM with Player 7: "Virtualized HV is fully supported for virtual hardware version 9 or later VMs on hosts that support Intel VT-x and EPT or AMD-V and RVI. To enable virtualized HV, select VM->Settings and navigate to the processor settings screen. Check the box next to  "Virtualize Intel VT-x/EPT or AMD-V/RVI."“



      First, I tried on 2 different computers (1 server running Windows Server 2008 R2 and 1 laptop running Windows 7 Pro) whose CPU support "Intel® VT-x with Extended Page Tables (EPT)" according to Intel's official website:


      Second, in the VM CPU settings, I tried the following options:






      In each case, when I try to add the Hyper-V role in the guest, it fails with the message "Hyper-V cannot be installed: A hypervisor is already running":





      I also tried using VMware Workstation 11 instead of Player 7 but it's the same.



      Can someone tell me what's wrong? How can I do nested virtualization using Hyper-V in the guest?


      Thanks in advance.
