I successfully installed Virtual box via a few simply apt-get commands under Ubuntu 8.04 via these instructions.

It started fine, after two small annoying, install this module, add this group messages. I was even able to install Ubuntu Intrepid from .iso. But from here it was down hill.

Attempting to start VM gives the error.

This kernel requires the following features not present on the CPU:
pae
Unable to boot - please use a kernel appropriate for the CPU

Some digging around, and confirmation that the current packaged version of Virtual Box doesn’t support PAE. You think they could tell you before successfully installing an OS. I’m running 1.5.6, I need 1.6.x

$ dpkg -l | grep virtualbox
ii  virtualbox-ose                             1.5.6-dfsg-6ubuntu1                      x86 virtualization solution - binaries
ii  virtualbox-ose-modules-2.6.24-19-generic   24.0.4                                   virtualbox-ose module for linux-image-2.6.24
ii  virtualbox-ose-source                      1.5.6-dfsg-6ubuntu1                      x86 virtualization solution - kernel module

Off to the Virtual Box Downloads to get 1.6.4
Don’t make the same mistake as I did and use the first download link, that’s the commercial version that doesn’t install what you expect, you need the OSE. Of course this is not packaged, it’s only source.

  ./configure
Checking for environment: Determined build machine: linux.x86, target machine: linux.x86, OK.
Checking for kBuild: found, OK.
Checking for gcc: found version 4.2.3, OK.
Checking for as86:
  ** as86 (variable AS86) not found!

Ok, well I go through this step like 4 times, installing one package at a time, I wish they could do a pre-check and give you all missing requirements. I installed bin86, bcc, iasl.

Then I got to the following error.

$ ./configure
...
Checking for libxml2:
  ** not found!

Well it’s installed, all too hard. Throw Virtual Box away for virtualization software. And why am I using it anyway. Because VMWare Server doesn’t work under Ubuntu 8.04 either because of some ancient gcc dependency. Sees I may have to go back to that. I just want a working virtualization people on the most popular Linux distro to install other current distros. It’s not a difficult request.
