LAB 8. VirtualBox

Objective:

· Familiarize students with Oracle VirtualBox

· Give students hand-on experience with creation of windows 10 virtual machine.

1. Download Disk image files

The IT department team at APIC have already downloaded disk image files and they are available at student share folder.

On the desktop open the shareholder (STUDENT Applications) the select OSI ISO -> Windows 10 .VDI file and copy Windows10 file at your document folder.

2. Start VirtualBox

You can start VirtualBox as follows:

· On a Windows host, in the standard "Programs" menu, click on the item in the "VirtualBox" group. On Vista or Windows 7, you can also type "VirtualBox" in the search box of the "Start" menu.

When you start VirtualBox for the first time, a window like the following should come up:

This window is called the "VirtualBox Manager". On the left, you can see a pane that will later list all your virtual machines. Since you have not created any, the list is empty. A row of buttons above it allows you to create new VMs and work on existing VMs, once you have some. The pane on the right displays the properties of the virtual machine currently selected, if any. Again, since you don't have any machines yet, the pane displays a welcome message.

3. Creating your first virtual machine

Click on the "New" button at the top of the VirtualBox Manager window. A wizard will pop up to guide you through setting up a new virtual machine (VM):

On the following pages, the wizard will ask you for the bare minimum of information that is needed to create a VM, in particular:

1. The VM name will later be shown in the VM list of the VirtualBox Manager window, and it will be used for the VM's files on disk. Even though any name could be used, keep in mind that once you have created a few VMs, you will appreciate if you have given your VMs rather informative names; "My VM" would thus be less useful than "Windows 10 64bit".

2. For "Operating System Type", select the operating system that you want to install later. The supported operating systems are grouped; if you want to install something very unusual that is not listed, select "Other". Depending on your selection, VirtualBox will enable or disable certain VM settings that your guest operating system may require. This is particularly important for 64-bit guests. It is therefore recommended to always set it to the correct value.

3. On the next page, select the memory (RAM) that VirtualBox should allocate every time the virtual machine is started. The amount of memory given here will be taken away from your host machine and presented to the guest operating system, which will report this size as the (virtual) computer's installed RAM. You can select 2048 MB RAM size.

4. Next, you must specify a virtual hard disk for your VM.

There are many and potentially complicated ways in which VirtualBox can provide hard disk space to a VM, but the most common way is to use a large image file on your "real" hard disk, whose contents VirtualBox presents to your VM as if it were a complete hard disk. This file represents an entire hard disk then, so you can even copy it to another host and use it with another VirtualBox installation.

The wizard shows you the following window:

Here you have the following options:

· To create a new, empty virtual hard disk, press the "New" button.

· You can pick an existing disk image file.

In this lab, you will pick an existing disk image that you have downloaded it. Choose the virtual hard disk file by clicking on the small folder icon as shown below:

Then select Create.

VirtualBox supports two types of image files:

· A dynamically allocated file will only grow in size when the guest actually stores data on its virtual hard disk. It will therefore initially be small on the host hard drive and only later grow to the size specified as it is filled with data.

· A fixed-size file will immediately occupy the file specified, even if only a fraction of the virtual hard disk space is actually in use. While occupying much more space, a fixed-size file incurs less overhead and is therefore slightly faster than a dynamically allocated file.

5. After clicking on "Finish", your new virtual machine will be created. You will then see it in the list on the left side of the Manager window, with the name you entered initially.

4. Running your virtual machine

To start a virtual machine, you have several options:

· Double-click on its entry (Windows10) in the list within the Manager window or

· select its entry (Windows10) in the list in the Manager window it and press the "Start" button at the top

3 Lab submission

Put your name and student ID in this lab document and submit by due date and time to APIC online learning system. Late submission penalties apply.

The lab work will contribute to your final assessment results with 8%

You need to Submit :

· Word document which include screenshots of your work ( step by step screenshots ) of how to use Oracle VB to install an operating system and the answers for the above questions.

ALL SCREENSHOTS SHOULD SHOW THE VM TASKBAR WHICH SHOWS DATE AND TIME.

DO NOT SNIP OR TRIM SCREEN SHOTS .
