Problem installing Vista 64bit with VirtualBox on a Vista 64bits

I want to configure a Dev VM on my Windows Vista 64. But the installation shows the following error:
Attempting to load a 64-bit application, however this CPU is not compatible with 64-bit mode.

I have windows Vista 64 bits, but it seems like VirtualBox is defining the VM with a 32bits processor.

It seems that you need a EM64T VT-capable processor to be able to load a 64 bit OS under a virtual machine.

For VMware, there is a utility and docs to look at here:

Check you BIOS to see if the VT option has been disabled. Enable it if at all possible.

Looking on the VirtualBox web site, it states this for running 64 bit guest OS's:

64-bit-VT or AMD-V capable CPU
Ensure AMD-V is enabled in BIOS
