I have an Intel E7300 Core2 Duo processor with 2.66GHz speed. I need to run a 64 bit winxp sp2 vmware image. My host operating system is Win 7. So I just installed the VMPlayer from www.vmware.com.

The problem is when I run the vm image it says "This host doesn't support VT". If I continue I see Widows shows an error message saying "Attempting to load an x64 operating system, however this CPU is not compatible with x64 mode".

My question is how do I run this vm without buying a new processor? Any other tools or software?

Wild ass guess here... VM needs Intel VT support to run a 64bit OS. Your motherboard's chipset does not support Intel VT. So either run a 32bit OS, or get new hardware. Or use a different virtual machine manager. But I might just be flat out wrong. – Will Jun 25 '10 at 19:02
@Will It’s the CPU, not the chipset. – kinokijuf Jan 24 at 15:33
@kinokijuf It must be supported First by CPU. Then by Chip set. Otherwise OS can not utilize it. – Shiplu Jan 24 at 16:55

Intel Core 2 Duo E7300 doesn't have Virtualization Technology (VT) support. Intel's website has a whole list of which processors support VT-x here.

enter image description here

So you cannot run 64-bit operating systems in a virtual environment. You will have to use a different processor which supports VT-x (or AMD-V in case of AMD processors).

Seems I have to buy the "YES" marked ones!! – Shiplu Jun 25 '10 at 23:50

Apparently VMware and VirtualBox don't support 64-bit guests without VT (at least, as of Aug 2009)

Since your CPU does not support VT (as Om Nom Nom pointed out), you'll have to either upgrade your CPU or switch to a virtualization product that does support 64-bit VMs without VT (Xen was suggested in the Serverfault question, but I don't think you can install Xen on a Windows host).

I'll go with Xen. Is it possible to install in Ubuntu? In fact I dont want to download another 32bit sister of this 24GB vmware image. It takes a lot of time to download. – Shiplu Jun 25 '10 at 23:54
Yep, you can install Xen on Ubuntu. Here are some instructions, although I'm not sure if they're for the very latest version: help.ubuntu.com/community/Xen – rob Jun 26 '10 at 0:40

Have you checked your BIOS to make sure that VT is enabled? Some machines (including mine) ship with it disabled. I just had to enable it in the BIOS and it was good to go...
