Whilst I’m waiting for my new hard disk to arrive for my Core-i5, I needed to use VirtualBox, so I decided to install it on my E5300 fileserver, which luckily has VT-x support, and of course is running a 64-Bit Ubuntu 9.10 install with 4Gb RAM.

It actually was easier than I expected, similar to the Fedora method you just add the repository to your /etc/apt/sources.list, import Oracle’s GPG key and run “sudo apt-get install virtualbox-3.2” as described here; which even pulls in the dkms system to rebuild the kernel modules automatically.

Then I just added my username to the vboxusers group and copied over my ~/.VirtualBox/ directory from the Core-i5, editing the paths to the VDI’s to point to the backups I made.

I had to upgrade my BIOS as it seems the one I was using didn’t actually have an option to enable VT-x, although it was detected in the flags of /proc/cpuinfo
