Problem

Everytime you go to power on a virtual machine you get asked the following question,

Virtual Machine Message
Virtualized Intel VT-x/EPT is not supported on this platform.
Continue without virtualized Intel VT-x/EPT?

And if you choose No it throws up an error. You need to choose Yes before it will let you power on the VM.

Solution

This is a problem of my own making, a while ago I was trying to enable Hyper-V on a Windows 8 VM, and needed to make a change in my VMware environment so I could add this Windows feature to the VM. I enabled the change globally on the ESX host (Instead of just on the machines .vmx file which would have caused me less problems!).

So I needed to remove the change I made.

1. Connect to the ESX host via SSH, and login.

2. You need to edit the /etc/vmware/config file, and remove the line I had added earlier [highlighted below].

[box]

vi /etc/vmware/config

Navigate to the line you want to remove with the arrow keys > Press I > remove the line > press {Esc}

:wq
