Symptoms

If Virtualization Technology (VT) is enabled in the BIOS to run 64-bit virtual machines:

Booting a 64-bit virtual machine with Paravirtualization generates an error:

Ubuntu 8: This kernel requires an x86-64 CPU, but only detected an i686 CPU.

SLES 10: Cool Software, but... This is a 32-bit Computer. You cannot use 64-bit software on it.

Windows 2008 Server: Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode.

Windows 2003 Server: Attempting to load an x64 operating system, however this CPU is not compatible with x64 mode. Please install a 32-bin X86 operating system.

You receive a message indicating that Long mode is required.

Cause

These errors are thrown by 64-bit guest operating systems if paravirtualization (VMI) is enabled.

Resolution

There is no 64-bit support for VMI when using ESX 3.5.x or earlier.

To power on 64-bit guest operating systems, you must disable VMI. To disable VMI:

Select the virtual machine in VMware Infrastructure Client.

Click Edit Settings > Options > Advanced.

Deselect Paravirtualization.
