Hardware Virtualization on a OptiPlex 755

Question

I have a fresh batch of OptiPlex 755 systems that just arrived. When trying to install my VM clients (Virtual PC 2007, VMWare Server 1.0.4, etc.) I've discovered that these systems/models do not appear to have any hardware virtualization available to my virtual machine clients. I have gone into the BIOS and enabled the option under the 'Performance' => 'VT for Direct I/O'. On a OptiPlex 745 it was just listed as 'Hardware Virtualization' not 'VT for Direct I/O', and likewise the option doesn't appear to have worked like the VT option on the OptiPlex 745s. Within Virtual PC 2007, under 'Options' => 'Hardware Virtualization' it is reporting 'Note: Hardware-assisted virtualization is not available on this computer.' The current configuration is: OptiPlex 755 - BIOS A03 Intel Core 2 Duo - Processor 4400 (2.00GHz) Windows XP Pro w/SP2 2.0 GB RAM ...any ideas? I thought this processor supported Hardware VT. The description in the BIOS for 'VT for Direct I/O' is as follows (which makes me assume VT SHOULD be available): 'This field specifies whether a Virtual Machine Monitor (VMM) can utilize the additional hardware capabilities provided by Intel(R) Virtualization Technology for Direct I/O' Thanks -Rob Haas

You have a E4400. That does not have virtualization.

As Hydralisk00222 stated, you are using the Intel Core 2 Duo E4400 processor. The lowest-end Core 2-series processor that supports Intel Virtualization Technology (Intel VT) is the Core 2 Duo E6300.
