    Is Intel VT-x/EPT not supported by Q9550?

      Hello Community,

       

      Is Intel VT-x/EPT not supported by Q9550?

       

      I am asking because a warning of VMware Workstation "Virtualized Intel VT-x/EPT is not supported on this platform" due to that I can't perform esxi host and GNS3 VM. My PC is a Dell Optiplex 780 in the Bio:

       

      Enable Intel(R) Virtualization Technology is: Checked
      Enable Intel(R) VT for Direct I/O is: Checked
      Enable Intel(R) Trusted Execution Technology is: Unchecked
      Enable CPU XD Support is: Checked

       

      See attached pictures for more info

      The Bio is updated to the latest version

       

       

      Thank you

          Actually, both VT-x and VT-d are supported by the (vPro-enabled) Q9550 processor. In order for these features to be used, this processor must be combined with a vPro-enabled chipset. I see that the Dell Optiplex 870 indeed has a vPro-enabled chipset, namely Q45, so these features should be supported.

           

          EPT (Extended Page Tables) is an Intel second-generation x86 virtualization technology for the memory management unit (MMU). EPT support is found in Intel's Core i3/i5/i7 CPUs (amongst others). Unfortunately, the Q9550, which is a Core 2 Quad processor, supports only first-generation x86 virtualization technology.

           

          Bottom line, VMware Workstation is not going to work on this processor as EPT support is a requirement. I have to say, why you would want to attempt to run VMware on this ancient, 9-year-old machine is beyond me. It can only support 4GB of memory, which is (IMHO) far too little to reasonably support VM operation.

           

          Sorry,

            Scott, thank you so much for this helpful explanation, I haven't changed the PC because I didn't understand the problem.

             

            You're rock buddy!
