Are you trying to install that in a VM? Nested virtualization isn't enabled out-of-the-box, VMware clients (Player & Workstation) have supported it for a while now. (And it looks like your CPU is new enough to support it well)
Shut the VM down, close the VMware application & add the following line to your .vmx
file:
vhv.enable = "TRUE"
(If Workstation/Player later complains about the vmx
being corrupted, your version doesn't support it. Remove the line to fix the file.)
VMware hypervisors support it so that you could test ESXi out in a local Workstation machine. However, it's also known to work for other virtualization OSes. (I used it for Hyper-V in Windows 8.1 so I could develop Windows Phone apps without upgrading my Windows 7 workstation)
