Re: Virtualized Intel VT-x/EPT is disabled for this ESX VM. You will only be able to run 32-bit nested VMs

Let me suggest the following alternative procedure:

1) For the guest operating system, choose "ESX Server 4" or "ESX Server 5," as appropriate.

2) On the processors tab, check the box next to "Virtualize VT-x/EPT or AMD-V/RVI."

3) Install ESX.
