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: CheckedEnable Intel(R) VT for Direct I/O is: CheckedEnable Intel(R) Trusted Execution Technology is: UncheckedEnable 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,

...S

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!

Subject: VT-x/EPT Not Supported Error on Intel® Core™ i7-1185G7 – How to Solve

Message:

Hello Intel Community,

I am currently using a Dell system with an 11th Gen Intel® Core™ i7-1185G7 @ 3.00GHz processor. While attempting to run VMware Workstation, I receive the following error message:

"This host supports Intel VT-x, but Intel VT-x with Extended Page Tables (EPT) is not supported on this platform."

Steps I have already tried:

Enabled Intel Virtualization Technology (VT-x) and VT-d in BIOS.

Verified Windows Features (Hyper-V, Windows Hypervisor Platform, Windows Sandbox).

Tested different BIOS/software settings suggested online.

The problem still persists.

From my understanding, this processor should support Intel VT-x, VT-d, and EPT.

My questions are:

Can Intel confirm whether the i7-1185G7 fully supports VT-x, VT-d, and EPT?

If it is supported, what steps should I follow to resolve this issue in VMware Workstation?

Are there any known compatibility issues or BIOS settings specific to 11th Gen Intel processors that I should adjust?

I will attach screenshots of the error messages for reference.

Thank you for your assistance.

Best regards,
[DHANUSH]
