[[Image:vmware-1a.png|thumb|right|550px450px|The VMware Workstation 12 application will allow you to create and administer '''4 different virtual machines''' ('''VM'''s) on your computer system. ]]
===Purpose of Lab 1===
* '''Correctly install the CentOS 7 FULL INSTALL DVD (c7host)''' on your SSD using '''VMware Workstation'''.
|}
=INVESTIGATION 1: CREATE AND INSTALL FIRST VIRTUAL MACHINE Create And Install Your 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.
===Part 1: Using VMware Workstation Pro to Create a New Virtual Machine (VM) ===
*'''Name:''' c7host
*'''Boot media / Installation:''' CentOS 7 Full Install DVD (image file)

# Although the images may be a little out of date (i.e. not exact), you can refer to this listing of installation screenshots for general reference:<br>[[http://matrix.senecac.on.ca/~murray.saul/ops235/ssd2/ installation screen-shots] ]<br>
# Power up the computer in your Seneca lab in '''Windows'''.
# If you haven't already downloaded the CentOS 7 Full Install DVD ISO, then download the following link for the CentOS 7 Full Install DVD image on your local computer: <br>httphttps://belmontmirror.senecacollege.ca/pub/centos/7/isos/x86_64/CentOS-7-x86_64-DVD-18041810.iso
# Plug your SSD drive into your computer. Note the drive letter for that device.
# Format your SSD to use exFAT, '''not NTFS'''. Open ''My Computer'', right-click on the SSD, and select ''Format...''. The dialog box should have the '''exFAT''' option selected, as the example to your right shows. Once selected, click ''Start''.
# Run the '''VMware Workstation Pro''' application (do '''<u>NOT</u>''' run VMware Player!).
# <span style="background-color:yellow;">In your VMware Workstation application window, click the '''Edit''' menu, then select '''Preferences'''. Under the '''Default Location For Virtual Machines''', enter the pathname for the newly created folder in your SSD device and click '''OK'''</span>.
# Click on the item labelled '''Create a New Virtual Machine'''.<br><br>'''NOTE:''' We will just be creating a "shell" for the VM the to contain our CentOS 7 Linux operating system.<br>This will allow us to configure the VM properly so it will boot-up properly in our Seneca labs.<br><br>
# Select the '''Custom (advanced)''' for the Virtual Machine Configuration setting and click '''Next'''.
# Click '''Next''' at the next screen to proceed.
# Select the '''I will in<u>s</u>tall the operating system later''' option and click '''Next'''.
# In the next screen, select '''Linux''' as the '''Guest Operating System''', and '''CentOS 7 64-bit''' for the OS ''version'' and click '''Next'''.# Enter '''c7host''' for the ''<u>V</u>irtual machine name'' and note the location where the image will be stored on your Windows machine and click '''Next'''.<br><br>'''NOTE:''' Since this "virtual machine" will be supporting other virtual machines (i.e. nested VMs), it is recommended to select a '''higher number or core processors''' (like 2 or 3).<br>You can can always change this setting later on to maximize the performance of running the "nested" VMs on your Host VM.<br><br>
# Select the <b>maximum number of processor cores</b> your computer supports and click '''Next''' .
# In the following screen, change the Memory from ''1GB'' to '''8GB''' (i.e. '''8192 MB''') and click '''Next'''.

# Make certain that your '''c7host''' VM is running, open the Bash Shell terminal and issue the command: <b><code><span style="color:#3366CC;font-size:1.2em;">su -</span></code></b> and enter root's password.<br><br>
# Change to the '''/root/bin''' directory.<br><br>
#Download the checking script by issuing the following Linux command:<br><b><code><span style="color:#3366CC;font-size:1.2em;">wget http://matrixcs.senecac.onsenecacollege.ca/~murray.saulops235/ops235lab1/lab1-check.bash</span></code></b><br><br># Give that downloaded shell script file execute permissions (for the file owner).<br><br>'''FYI:''' Your this checking script will not work unless you issued "'''su -'''" instead of just "'''su'''".<br><br>
# Run the shell script and if any warnings, make fixes and re-run shell script until you receive "congratulations" message.<br><br>
#Arrange evidence (command output) for each of these items on your screen, then ask your instructor to review them and sign off on the lab's completion:
