# Download and burn on a DVD a copy of the CentOS 7 installation DVD (64 bit edition) from the CentOS web site or the Belmont server.<br>'''Note:''' we'll be using the 64 bit version of CentOS because all of our lab computers are equipped with Intel 64 bit mainboards and CPUs, and any computer you bought in the last few years for yourself will be 64bit as well.<br><br>

#* '''Seneca's mirror of CentOS:''' https://mirror.senecacollege.ca/centos/7/isos/x86_64/CentOS-7-x86_64-DVD-2009.iso <br>This is very fast, but is only accessible from within Seneca's network - you can't access this from home. You can burn this disc on the machines in the Open Lab.)<br><br>

<ol>

<li value=4>Customize your installation following these guidelines:

<li>Free up at least '''100GB''' of disk space by shrinking the '''/home''' partition (At least '''40 GB''' for root (/) and '''40GB''' for /home). Since your machine will have far fewer users and more virtual machines than a typical installation, we will need that space elsewhere.

<li>Create a new logical volume for '''/var/lib/libvirt/images''' and give it the space made available by shrinking /home (You will need enough space for up to 10 virtual machines at 8GB each plus room to compress/extract images).

</ul>

</ul>

At this point you have a basic Centos system installed and updated. This will serve as a host for the virtual machines where you will do the majority of the work in this course. All the rest of our labs will assume you have this basic system running. If, for any reason, your system becomes corrupted during the semester, you'll have to redo this lab to be able to continue with the remaining uncompleted labs. You are responsible for YOUR system. If you do not perform back-ups you have taken this risk on yourself. Poor planning on your part does not constitute an emergency for anyone else.

==INVESTIGATION 2: VIRTUAL MACHINE INSTALLATION==

===Configuring a VM host===

#* Install the required virtualization software

#* Start and enable the virtualization service

#* Stop and delete the '''default''' network.

#* Use the '''plus sign''' to add a new virtual network using the following options:

#:* Use the '''last two digits of your student number for the third octet of network IP address''' (for example, if your student number is 000-000-0<b>90</b>, the network address would be 192.168.<b>90</b>.0/24.

#:* Ensure the DHCP range will allow you to assign '''at least 10 static IP addresses outside it''' (note: leave the low numbers available for static addresses).

#You will notice that the server installation defaults to a command-line interface. This is normal, and we will only be using this interface during this course.

#Ensure your machine has a network connection by running the command

{{Admon/tip|Default for network config for onboot|If you've turned on your networking interface during installation - it will be turned on by default. If you've left the network interface off during the installation - it will be off by default.}}

<ol><li value="4">Once you have a working connection - update your machine.</li></ol>

===Cloning a Virtual Machine===

<ol>

<li>'''If you are confident with what you have done so far, you may clone your existing machine to create the others by performing the following steps:'''</li>

<li><ol type="a">

<li>Record in your notes the steps for cloning a vm.</li>

<li>Use the host command to check for connectivity</li>
