Your objective is to set up a virtual server using VirtualBox on your Fedora machine. Please call it centos52.YOURDOMAIN.
Since you did a yum update last class, it would be a good idea to reboot since you possibly (likely, even) have a new kernel and VirtualBox needs to be compiled and run against that new kernel.
You also likely need to install gcc, make, and kernel-devel, although some of you of course may have already some of or all of these packages installed.
You can retrieve the latest version of VirtualBox from VirtualBox.org.
Once you have installed VirtualBox (by default, it adds a menu item to your Applications->System Tools menu), I suggest bringing up the client and take a look around. There's an excellent manual available from the interface.
Now you need to pull down CentOS. Please pull down the DVD installation version from CentOS.org. This will take a while.
Once you have pulled it in, use the VirtualBox interface to create and start a new machine. When it asks for a DVD/CD, make sure that you tell it that you want to use an image file, and then point it at the ISO file (not a physical DVD) that you pulled down.
A journal is due for this assignment. Make sure that you document in your journal all of the steps that you went through, following the guidelines on the class home page. Please share the workload so that all team members get experience with all aspects of the work. Don't forget to assign your work percentages to yourself and your other teammates in your journal. Please turn in a printed copy of this assignment at the beginning of class on Tuesday, February 3rd.
