Hands-On Assignment 3 - VirtualBox and CentOS

Instructions

Using a Virtual Machine software package such as Oracle Virtualbox or VMWare, create a virtual machine on your host computer. Then install an operating system such as CentOS, Windows, Linux, or a MAC OS.

After completion, start the OS and open a terminal (or command window) and issue  three commands:

$ whoami

$ hostname

$ ifconfig (if the os for the VM is Mac or Linux, or ipconfig if the os for the VM is Windows, or ip addr show in some other versions of Windows.)

Then take a screen shot of the results from those commands within the os while it is running on your VM and send it as a PDF or image file. The screen shot could be an image file from a phone or camera. The screen shot must show the VM logo (such as Oracle Virtualbox). The screen shot can’t be from the host computer; it must be within the virtual machine

 ------------------------------------------------------------------------------------------------

An example of installation procedures:

These instructions are based on Virtualbox as the VM software and CentOS as the VM OS on a MAC OS 10.10.5. Virtualbox or VMWare creates a virtual computer that functions as if it has the equivalent hardware as the host machine. CentOS is an example of an operating system that can be installed on that virtual machine. You could use Windows or Linux if so desired.

Do a Google search for Oracle Virtualbox and a CentOS free download for your platform. Be sure to get the right ones for your platform, for example “*.dmg” for MAC. Some downloads are OS version specific, for example, MAC OS 10.10.x.

Install your VM. In the case of Virtualbox for MAC, just double click “Virtualbox-xxx.dmg”. From the pop-up window, drag “Virtualbox” onto the “Application” folder. Close the pop-up window. Double click “Virtualbox” icon to launch Virtualbox in the Virtualbox window. There is no OS installed yet. You can install more than one OS on the VM, but only one OS can run at once. To toggle between the Virtualbox and the host environment, press the “command” key on the MAC. There are similar methods used in other virtual machine environments.

On the top panel click “New”. A new smaller window pop-up within. Enter a “Name” for this VM OS you are about to create, e.g. “CentOS_1”.

Choose a “Type” for the OS. The CentOS’ type is  “Linux”. For “Version”, choose “Red Hat (64-bit)”. 

Adjust “Memory size” to 8GB. 

For “Hard Disk”, choose

• “Create a virtual hard disk now”, if you do not have one already.
• “Use an existing virtual hard disk file”, if you are using one from other person or previous created one.

Click “Create”.

Another window pops-up. For “file location”, leave it alone, or click the right icon next to it for determining your own location.

For “Hard Disk File Type”, choose,

• “VDI (Virtual Disk Image)”, if you don’t need to port it to another computer.
• “VMMDK (Virtual Machine Disk)”, if you want to port it to another computer.

Click “Create”. 

Another window pops-up. It asks where the bootable file is. Right click on the icon next to it, choose the CentOS-xxx.iso file (a CD/DVD disk image) or any virtual OS image that you have downloaded. This will create the virtual OS on the VM. For CentOS, you will need to go through configuration to choose files and features you need. Then on the second configuration window, be sure to create a root password and a user account other than the root. Give it the administrate privileges, that will make it easier to do things later on. But be aware that this user can also damage the system, if you are not careful. The good thing is that you can always create another VM and VM OS.

------------------------------------------------------------------------------------------------

The alternatives to CentOS on a Virtualbox VM might be to use VMware or Virtualbox to create your VM. You could then install some version of Windows or Linux.

Windows 10 may have difficulty in installing CentOS on a Virtualbox VM or on a VMWare VM. (Creating your VM using VMWare and installing Windows 7 works very well if you are working with a Windows host machine.)
