VMWARE ESXi and Dell PowerEdge 64bit problem

Today, a refurbished Dell PowerEdge 2900 Tower arrived today, and I imediately plugged it in and installed ESXI. I figured out how to create a vmware image so I created my first one to be Windows 7 64bit. When I started the image up I recieved the following message from vmware:

"...this virtual machine is configured for 64-bit guest operating systems. However, 64-bit is not possible.... verify that the BIOS settings enable VT and disable 'trusted execution'..."

What the heck is this? I am not too familiar with the Dell PowerEdge BIOS settings so I hope someone there is, and knows what I need to change. This system is refurbished. It has dual Xeon 64bit processors with 24 GB of ram.

Please advise.

You need to boot to the BIOS Setup (F2) and enable hardware-assisted virtualization (VT) ... under Processor.

In your server's BIOS, you need to enable Intel-VT (or AMD-V) to be able to run 64-bit VMs. I'm not sure if the 2900 servers had that feature, though. Let me do a little checking. In the meantime, go into your BIOS and see if you can find that option to enable.

Yes, they did, and I believe all configurable processors support VT.

Under Processor Options should be:

Virtualization Technology (Disabled default)

That was easy. Thanks for looking this up for me. I a bit paranoid making changes to this machine, and even more cautious about setting up ESXi as I go. I will post more, tomorrow... and will probably start wondering how to take all my vmware server 2.0 images and move them into this server. ;-). The title of that question will be Moving Images from VMWARE 2.0 to VMWARE ESXi.
