Yes, notoriously wrong indeed.
In my case, I have a Xeon X3220, which they clearly indicate to support both VT-x and EPT (http://ark.intel.com/products/28034/Intel-Xeon-Processor-X3220-8M-Cache-2_40-GHz-1066-MHz-FSB), but when I install ESXi 5, the message "Virtualized Intel VT-x/EPT is not supported on this platform" still appears. I take that as the X3220 does not support EPT? (Although it may support VT-x as according to the CPUZ readings)
So is there any official confirmation about this? And is there any workaround for me to install ESXi on a Workstaion 9?
This misannoucement really annoys me.
Thanks for the information anyway.
