Virtual Machines

We will be using a virtual machine image running Linux 2.6 kernel using the Debian distribution. This will run using the freely-available VirtualBox software.

Each virtual machine includes the source code for Operating System Concepts and Operating System Concepts Essentials.

Obtaining Virtual Box

Visit www.virtualbox.org and click on the download tab.

Download the virtualbox platform packages for your appropriate system and install the software.

We are providing two separate approaches for installing the Linux VM: (1) As a VirtualBox appliance, and (2) as a disk image. For most users, we recommend installing it as a virtualbox appliance.

Installation as a VirtualBox Appliance

Click here to download the file OS-Concepts.ova

Double-click on the downloaded file. This will open the following window



Choose the Import button.

Proceed to Running Linux


Installation Using a Virtual Machine Image

Click here to download the file debian-cmpt352.vmdk.zip (zip) [ Best for those on OS X ]

Click here to download the file debian-cmpt352.7z (7zip) [ Best for those on Windows ]

Extract the zip file to debian-cmpt352.vmdk

Installing the Virtual Machine

1. Click on the button New

2. This will open a virtual machine wizard for creating a new virtual machine.

3. Give your virtual machine a name. The operating system type is Linux, and it is a Debian distribution.

4. Choose the default value for base memory size

5. Click on the radio button for using an existing hard disk (this is debian-cmpt352.vmdk)

6. Click on the button for navigating to the location of debian-cmpt352.vmdk



7. Click Create.


Running Linux

Highlight the virtual machine you wish to run (OS-Concepts) and click on the Start button:




This will commence the Linux boot process.

The default username is os and the password is os as well

There is a root user and the password is cmpt351


Exiting Linux

Choose

System -> Shutdown

Editing Files

There are no graphical development tools built-in. Rather, you will have to use a command line

Applications -> Accessories -> Terminal

where you will find gcc, our C compiler.

There is also an editor - gedit

Applications -> Accessories -> gedit Text Editor

However this is a text editor only. You can use it to edit your C files, yet you will have to compile it using the command line.
