Install VirtualBox In Hardy

I recently switched back to using Hardy Heron because after upgrading to 9.04 jaunty i didnt have any sound on my pc, iv hit the same problem before when upgrading my kernel but as i didnt blog it i cant remember how i fixed it so just decided to go back to what works for me, the one thing that didnt work for me straight away in ubuntu 8.10 hardy was virtualbox so im blogging how i solved it to keep for future referencing.

Firstly install virtualbox from the repositories by opening the terminal and entering;

$ sudo apt-get install virtualbox

Ok all that went fine for me but then when i created a new virtual machine and tried to run it i got an error

VBox status code: -1908 (VERR_VM_DRIVER_NOT_INSTALLED).

so after a little searching i found the answer which was that you need to install modules for your kernel version, so back to the terminal again and enter;

$ uname -r

to find your kernel version, mines was;
2.6.24-24-generic

so in the terminal i just entered;

$ sudo apt-get install virtualbox-ose-modules-2.6.24-24-generic

(You need to change the kernal numbers at the end to match your output from your uname -r command)

Then restart virtualbox backend with the commands;

$ sudo /etc/init.d/vboxdrv restart && sudo /etc/init.d/virtualbox-ose restart

Then at the top of your desktop go to
System >> Administration >> Users and Groups
click unlock then manage groups and scroll all the way down near the bottom where youll see a group called vboxusers click properties and make sure your username has a tick beside it and click OK.

Now you just need to reboot the pc and virtualbox should be running perfect for you to install any other OS's inside your ubuntu.
