: The virtualized OS is installed and run in a window under another OS. Special software is used to manage the entire process, referred to as the '''hypervisor'''.<br><br>
: '''Advantages''' of Virtualization:<ol><li>You can run VM from an '''ISO image file''' or a '''VM file'''.</li><li>One or more virtual machines can be run at the <u>same</u> time.</li><li>The '''guest''' OS '''shares hardware''' with the '''host''' OS and possibly other virtualized systems.</li><li>The '''guest''' systems have '''network access''' through the host.</li></ol>
: '''Installation Tips:'''<ol><li>Virtualization requires a '''compatible processor''': not all processors support that feature.</li><li>Your '''BIOS''' should be set to '''<u>enable</u> Virtualization'''.</li><li>Popular VM software for '''Windows''', '''Apple''' and '''Linux''' OS include:<ul><li>VMware</li><li>Oracle Virtual Box</li></ul></li></ol>

<span style="color:red;">'''ATTENTION''': This tutorial relates to an interest topic and is NOT worth marks.</span><br><br> In this sectioninvestigation, you will first ''download'' and ''install'' the '''VirtualBox''' VM application on your home computer,<br>then you will then ''download'' and unzip the '''Knoppix Live Distribution VM''' file to your computer.
# Launch the '''Knoppix''' Linux distribution by clicking the '''Launch''' button.<br><br>''''''NOTE:'''''' Your '''file manager''' will open and display both the '''Knoppix virtual machine icon''' and a '''Knoppix Installation ISO file'''. You will be launching the Knoppix Virtual machine in the '''Virtualbox''' application.<br><br>
# '''Double-click''' on the icon Knoppix.vbox in the Virtualbox menu.<br><br>
# Another dialog box will appear. '''Double-click''' on the '''Switch''' button when prompted to enter '''scale mode'''or '''Switch''' to scale mode.<br><br>'''NOTE:''' You should notice that you can switch between your Knoppix VM and your Windows computer which is referred to as the '''host machine'''.<br><br>

# '''Click''' the following link to access the '''Oracle Virtualbox''' application download website:<br>[https://www.virtualbox.org/wiki/Downloads https://www.virtualbox.org/wiki/Downloads]<br><br>
# In this website, '''click''' the link corresponding to your '''computer's operating system'''<br>to download to your computer.<br><br>
# '''Install''' the downloaded '''Virtualbox''' VM application on your computer.<br><br>'''NOTE:''' You may be required to allow '''authorization''' to run this program, select to install devices (if prompted) and to '''restart''' your computer after installation.<br><br>
# Open a '''File Manager''' application and '''navigate''' to directory that the '''Knoppix.zip''' file<br>was downloaded (eg. '''Downloads''').<br><br>[[Image:knoppix-file.png|thumb|right|280px|Knoppix VM file contained in the zipped file.

# '''Unzip''' the downloaded zip file (In MS Windows: ''Right click'' and Select "''Extract All''" )<br><br>'''NOTE:''' The contents of this zipped file should appear in another file manager window.<br><br>
# Navigate to the folder containing the ''extracted zipped files'' and '''double-click''' the file called '''Knoppix.vbox''' to launch the Knoppix VM.<br><br>'''NOTE:''' By '''double-clicking''' on this file (even if the VirtualBox application is not running)<br>it will launch the VirtualBox application and start the Knoppix virtual machine.<br><br>'''For Mac Users:''' If you experience an error message regarding the Kernel extension,<br>click on '''System Preferences''', select '''Security and Privacy'''<br>and click to '''allow Oracle''' service extensions to run on your machine.<br><br>If you have difficulty running Knoppix on your home machine/laptop you may ask your <br>'''Learning Centre ULG leaders''' for additional help in troubleshooting why Knoppix<br>is not working on your home machine/laptop.<br><br><table align="right"><tr valign="top"><td>[[Image:knoppix-start-menu.png|thumb|right|150px|'''Knoppix Start button''' (icon on the '''left''').]]</td><td>[[Image:knoppix-desktop.png|thumb|right|280px|The '''Knoppix Linux desktop environment''' has a similar look as the MS Windows desktop environment.

# Open the ''Knoppix start menu'' and select '''logout''' and '''shutdown''' to end your Knoppix Live session.<br><br>
# List '''4 applications''' that are contained in the Knoppix Linux Live distribution.
