Your objectives are to install VirtualBox on your Debian server, and then install CentOS 6.2 as a virtual server inside of VirtualBox. First, install VirtualBox. You can install the full VirtualBox from VirtualBox.org, or you can install it from a Debian repository.
Next, pull down an ISO of CentOS 6.2. Probably the best ISOs are either "CentOS-6.2-x86_64-netinstall.iso" or "CentOS-6.2-x86_64-minimal.iso" since either is quite small and the installation with either is usually fast (depending, of course, on how much network bandwidth you can commandeer if you decide on the netinstall; the minimal install doesn't need network bandwidth.) You can find all of the different possibilities for ISOs and downloads by looking at the download area of CentOS.org. (Alternatively, you might try a bittorrent version — it sometimes can be quite fast.)
Now use the "create a new machine" option on VirtualBox; use a VDI (not a real partition) and this disk image doesn't need to be very large (30 gigabytes is more than sufficient). Give the machine only one processor and 1 gigabyte of memory. Make sure that your new virtual server's network device is visible to the lab (do not use an internal-only or NAT configuration). See the VirtualBox networking documentation for more information about your choices.
As to the new virtual server's internal configuraiton, you don't have to install any graphical interface (indeed, the minimal doesn't offer anything other than command line by default), but you are welcome to do so if you like. For an ip number, please use your next IP number, (i.e., 192.168.10.(GROUPNUM+4)*10+1, thus GROUP #1 would use 192.168.10.51 for this assignment.)
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 Wednesday, June 13.
