Installing Windows 8 Client Hyper-V inside VMware Workstation/Fusion/ESX

Typically I used to try latest version of Windows on VMWare Player, Workstation or VirtualBox. Recently I was trying to set up a Windows Phone 8.0 development environment inside a VMWare virtual machine.

I tried to enable Hyper-V platform components in my Windows 8.1 Preview Virtual machine. It shows an error.

Hyper-V cannot be installed: A hypervisor is already running

  • Unable to use Hyper-V platform inside a Windows 8 virtual machine
  • When trying to enable/install Hyper-V in a Windows 8 virtual machine, you will see the above error:

SOLUTION:

Solution for this problem is to edit your VMware Virtual Machine configuration(.vmx) file in your Windows 8 Virtual machine stored location.

  • Switch off/Shutdown your VMware virtual machine
  • Edit the corresponding .vmx file
  • Append the following entries to the vmx file (verify entry if already exists)

hypervisor.cpuid.v0 = “FALSE”
vhv.enable = “TRUE”
mce.enable = “TRUE”

  • Save the changes
  • Start your Windows 8 VMware Virtual machine
  • Now go to Control Panel –> ‘Programs and Features’ –> Turn windows features on or off
  • Viola!,  You can now enable ‘Hyper-V Platform’ . Now you can install Windows Phone SDK on your Windows 8 Virtual Machine
