If you want to test Ubuntu 12.10 (Quantal Quetzal) without bothering yourself in partitioning your hard drive or dual booting with another OS, you can use VirtualBox which allows to install multiple operating systems (Linux, Windows, Mac OS X, etc.) in your host machine. This tutorial will explain to you how to create a virtual machine and how to install Ubuntu 12.10 in it. These steps are also applicable on other Ubuntu versions (12.04/11.10, etc.).

If you are working on a host machine running Ubuntu, you can install the latest version of VirtualBox (version 4.2.0) with these commands:

echo "deb http://download.virtualbox.org/virtualbox/debian $(lsb_release -sc) contrib" | sudo tee /etc/apt/sources.list.d/virtualbox.list

wget -q http://download.virtualbox.org/virtualbox/debian/oracle_vbox.asc -O- | sudo apt-key add -

sudo apt-get update

sudo apt-get install virtualbox-4.2

For other operating systems, you can download the appropriate file from here. Also, you need to download the iso image of Ubuntu 12.10 from here (currently in Beta 1).

Creating The Ubuntu VM (Virtual Machine)

Open VirtualBox and click New, then in the VM setup wizard, click Next and enter a name for your VM (Ubuntu 12.10 for example):


Note: Once you write "Ubuntu", the type of the OS will be detected automatically.

In the next screen, select the RAM size you want to allocate for the VM in megabytes. In this example, we will keep default settings (512 MB):


In the next screen, keep "Start-up Disk" and "Create new hard disk" options selected, then click Next:


Select "VDI (VirtualBox Disk Image)" and click Next:


In this screen, you can choose any option, but it is recommended to select "Fixed size" because it will run faster with less errors:


Next, set the VM size, this depends on the free disk space you have on your physical hard drive (no less than 5GB):


Once your virtual machine is successfully created, right click it in the VM VirtualBox Manager and select "Settings":


Open the "Display" tab and check on "Enable 3D Acceleration," then click OK:
