I get this message while trying to install Ubuntu 12.04 as a guest in VirutalBox 4.1.18, on an Ubuntu 10.04 host.
This kernel requires the following feature not present on the CPU: pae
Some host specs:
- The host's kernel is:
Linux 2.6.32-41-generic-pae GNU/Linux
- lscpu (host):
Architecture: i686
,CPU op-mode(s): 32-bit, 64-bit
grep --color=always -i PAE /proc/cpuinfo
does showpae
in its output.
The 12.04 iso used is: ubuntu-12.04.0-desktop-i386.iso
As a comparison/check, I downloaded and installed Linux Mint 13 Cinnamon to the same host on the exact same VM (I just changed the .iso image). It worked fine. Its iso is: linuxmint-13-cinnamon-dvd-32bit.iso
It seems (to me) that I have pae.. what is going on here?
Update: I had assumed that Linux Mint also required pae (being Ubuntu based), but I've just run; grep --color=always -i PAE /proc/cpuinfo
in the Mint VM. It showed no output. So it seems the issue may lie with VirtualBox. If that is the case, how can I get Virtualbox into pae mode?
