Hi

My Processor is X9000
# Dual Core
# Enhanced Intel Speedstep® Technology
# Intel® EM64T 1
# Intel® Virtualization Technology
With 4GbRam

I setup VT on the Bios host
My OS Host Vista Family Premium SP1 32 bit
My OS Guest Ubuntu 8.10 64 bit

I activated on VirtualBox
ACPI
IO APIC
VT-x/AMD-V


When I boot the Ubuntu CD a message tell me:
This kernel requires an x86-64 CPU, but only detected an i686 CPU

You also need PAE. Enable that and you should be done.

Sorry forgot to mention :

PAE/NX activated

Same problem
