I can tell you from experience that this is because VT is NOT enabled in the BIOS. Take a look at this thread:

HP DL380G4 with Intel Xeon3.0 GHz processor. Using Smartstart - I can install Windows 2008 - 64 Bit edition. No problem. Than I installed VMWare ESX 3.5 with latest updates. Trying to install Same Windows 2008 - 64 Bit ; no go. It gives me the message "Info: Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode." I am sure that CPU does support 64 Bit becuase I was able to install it directly on the hardware. Googling pointed to various direction including 1) checking the "Virtualization option" in BIOS - there is no option like that 2) Modifying the line in .VMX file on HP servers SMBIOS.reflectHost=TRUE No affect. 3) Upgrading the firmware on the server - done - no change. >From what I understand - VMWare ESX 3.5 doesn't have a 32 bit and 64-Bit editions. Any help idea to check further will be appreciated.
