[SOLVED] This kernel requires x86_64 CPU

[Notorand.IT]

but only detected an i686 CPU.

This happens while trying to install from ISO CD image Ubuntu Server 12.04.3 inside Kubuntu 13.10 with graphical GUI.
This is the first time I try 64bit architectures within desktop graphical GUI, but it's not the first time within 64bit server architectures.
Useless to say it works in the server environment.
Guest is Linux architecture is x86_64:

Code: Select all

uname -m
x86_64

with kernel

Code: Select all

Linux version 3.11.0-13-generic (buildd@roseapple) (gcc version 4.8.1 (Ubuntu/Linaro 4.8.1-10ubuntu8) ) #20-Ubuntu SMP Wed Oct 23 07:38:26 UTC 2013

.
VirtualBox is installed from VB repo and is v4.3.2r90405 with Extension pack v4.3.2r90405.
Am I doing anything wrong? If so, what?
TIA.

[UPDATE] Read below!

Make sure you select a 64bit template when creating the VM. Make sure VT-x is enabled in the VM settings.

Post a VM log file if you want to continue the discussion: Minimum information needed for assistance.

Gotcha! Ubuntu is 32bit, Ubuntu 64bit is .. well ... 64bit! My fault. Thanks.
