While attempting to install a 64bit OS in ESX Server you receive the following message

Host CPU is incompatible with the virtual machine’s requirements at CPUID level 0x80000001 register ‘edx’.

host bits: 0000:0000:0000:0000:0000:0000:0000:0000

required: xx1x:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx

Mismatch detected for these features:

*Longmode; required when virtual machine is configured for a 64-bit OS.





Cause:

The Virtualization Technology (VT) Extensions have not been enabled in the server BIOS.

Solution:

To install and configure 64bit operating systems in ESX Server requires that Virtualization Technology (VT) Extensions be enabled in the server BIOS settings.

Change the setting on BIOS for Virtualization.
