VMware Fusion 5: Enable VT-x/EPT inside a virtual machine

VMware has done a great job in recent versions of Fusion, Workstation and vSphere when it comes to allowing users to run other hypervisor applications inside a virtual machine.  In fact, many of my recent blog posts here at virtualizationadmin.com are using Hyper-V servers that I have running under VMware Fusion 5.

To enable this feature inside one of your virtual machines,

  1. Make sure the virtual machine is in a powered off state
  2. Open that virtual machine’s properties page
  3. Select the Processors & Memory page
  4. Select the checkbox next to Enable hypervisor applications in this virtual machine
  5. Restart the server


Once this support is added, you should be able to, for example, install the Hyper-V role on a Windows server.
