In order to save money and resources when learning to install, manage, and connect Linux machines to form networks, we will be using '''Virtual Machines''' for this course. In fact, we will be using two virtualization programs: In lab1, we will create a Centos7 Host virtual machine (c7host) in the virtual program called '''VMware Workstation''' (this host will be stored on your Solid State External Drive (SSD). Then in lab2, we will install another Virtual package on your host VM called '''KVM''' which will be used to create 3 other virtual Machines (VMs) that will be used to learn about Linux system administration for the remainder of this course.
It is ESSENTIAL to have a '''Solid State Drive (SSD) with a minimum storage capacity of 250 240 GB''' to perform your lab sessions and provide a host for your other Centos7 host and other VMs that you will create in lab2.
* '''Disable Linux Kernel security enhancements''' to allow easier internal networking connections (to be reactivated in a later lab).
=INVESTIGATION 1: CREATE AND INSTALL FIRST VIRTUAL MACHINE (c7host)=
In this lab, you will learn how to install your '''Centos Full Install DVD''' as a virtual machine using the '''VMware Workstation''' application.
Make certain to record your observations of this install in the comparison chart for '''c7host''' in your '''lab2 logbook'''.

Click the '''Browse''' button and specify the path of your downloaded Centos7 Full install DVD (most likely file is contained in your Downloads folder). When finished, click on the '''OK''' button</span>.
# You will return to your c7host VM. Click the play button near the top to boot your c7host VM for the first time.
