Ubuntu Server on VirtualBox returns error This kernel requires the following features not present on the cpu: 0:6

I installed Ubuntu Server 8.04 inside a VirtualBox (v 2.4.1_OSE) virtual machine.
The installation went smooth, but when I wanted to boot into my Ubuntu Server, it returned the following error right after GRUB:

This kernel requires the following features not present on the cpu: 0:6
Unable to boot – please use a kernel appropriate for your CPU

Screenshot or it didn’t happen?

Ubuntu Server on VirtualBox returns error

How to solve:

This can be easily resolved by enabling the PAE/NX option in the virtual machine’s settings.
This will expose the PAE of your CPU to the virtual machine.

Just:

  1. go to the homescreen of Virtualbox
  2. select your virtual machine
  3. click the ‘settings’ button on top of the screen
  4. click the tab ‘Advanced’
  5. check the box next to ‘PAE/NX’

Like in this screenshot:

Now, you can fire up your virtual machine again, and it will start up without this error.
