Windows 7 Guest Running XPM Mode - How to Enable Hardware Virtualization?

I have attempted several searches on this and apparently I have not nailed the right search terms.  I just keep getting the traditional "Turn on hardware virtualization support in BIOS" or "Enable paravirtualization, etc. in ESX" - neither apply here.

I am running an 64-bit workstation (i7 based with 24GB of RAM).  I do in fact have the Intel virtualization enabled in BIOS.

I am running VMware Workstation v.7.1.1 Build 282343 on Windows Vista Pro x64 Edition, SP2

I am running Windows 7 Pro x64 Edition virtual guest machines.

I am attempting to run the Microsoft XP Mode (old Virtual PC technology).  However, I continue to get the Hardware Virtualization not supported error.

At first I thought it would be a simple BIOS setting, so I hit F2 during boot of the virtual guest and went in to the virtual machine BIOS - no such setting.

Unlike ESX, there are no virtualization settings like Paravirtualization, that I have been able to locate under the advanced virtual machine options (including when the VM is powered off).

Additionally, the closest I have found is the Virtualization engine settings on the virtual CPU, but I have not found a combination of settings that works.

Ideas?  Surely someone is doing this...

Sorry about the Apple zones - my mistake - cached from a previous question.

If I read youi post correctly, you are trying to run a virtual machine from inside a virtual machine (the Windows 7 VM). I don't think you can do that with VMware Workstation. At least such is my understanding.

If you wish to move forward this way, you could make Windows 7 your real host and Vista your guest. Then XP mode should be available to the real host. ... Thinkpads_User

Thanks, but you had it correct the first time.  I am creating Windows 7 guests as a lab environment to verify functionality of all of a customer's software packages prior to upgrade.  Some of those packages may require XMP, and therefore I need to be able to demonstrate that as well.  While I could go Win 7 on a host, logistically it would be very difficult given the current arrangement and needs of the lab environment.  Since XMP is a common feature on Win 7, I am hoping that there is a way to do this...but maybe not.

I don't think VMware Workstation supports such a thing.

You might be able to create a reasonable workaround by having a regular XP guest machine to do your testing. You should be reasonably assured the software that works in the XP guest will work in XP Mode.

Not by this customer it wouldn't.  While I am well aware there are ways to approximate this experience, my original question stands - Can it in fact be accomplished in VMware Workstation 7?  I have seen nothing on the VMware site that says yes or no.  Figured I would ask here first, but if no one knows than I will open a ticket Monday AM with VMware.

I cannot readily find a VMware reference, but I see a number of user references to that say that VMware Workstation does not have this capability (which is my own understanding), and also that an inner guest can only be 32-bit.  Let us know about VMware Support when you get it.  ... Thinkpads_User
There is an additional download on the m$ XP mode download site which you can also install, and then you won't need hardware virtualization:


(it's the third download in the list, with the 2 **)
Add the following statement to your vmx file for your Windows 7 guest.

monitor_control.restrict_backdoor = "TRUE"

Good Luck
