|colspan="2"|{{Admon/important|Using a Kickstart file with a local install|Under most circumstances, a network install would be drawing the installation data from a server in the local network, allowing it to transmit data at higher speeds than we can achieve over the internet. If your download speed is slow enough that network installs are failing, it is acceptable to install these VMs from local media. However, you will still need to provide a kickstart file to Centos3. <br /><br />To do so, start the install process as normal for an installation from an iso file, but when presented with the menu giving you the option to 'Install CentOS 7' or 'Test this media & install CentOS 7', highlite highlight 'Install CentOS7' and press '''<tab>'''. This will open a prompt at the bottom of the window for you to enter grub configuration options. Type '''inst.ks=https://ictraw.senecacollegegithubusercontent.cacom/~ops245OPS245/labs/main/centos7-kickstart-local.cfg''' andf and hit '''<enter>'''.}}

# We will now learn how to download a compressed image file and XML configuration file and add it as a VM to the Virtual Machine Manager menu.
# Issue the following commands:<ul><li><b><code><span style="color:#3366CC;font-size:1.2em;">wget https://ictmatrix.senecacollege.ca/~ops245/centos4.qcow2.backup.gz</span></code></b></li><li><b><code><span style="color:#3366CC;font-size:1.2em;">wget https://ictmatrix.senecacollege.ca/~ops245/labs/centos4.xml</span></code></b></li></ul>
# Use gunzip with elevated privileges to decompress the qcow2 image file into the '''/var/lib/libvirt/images''' directory.
# Issue the command: <b><code><span style="color:#3366CC;font-size:1.2em;">sudo virsh define centos4.xml</span></code></b>
# Inside each virtual machine, run <b><code>ip a</code></b> on the command line. Open a Terminal window in centos1 to do so. You'll need the IP address of each machine for the next steps.
# Switch to your '''c7host''' VM, open a terminal, login as root, and change directory to '''/root/bin'''.

# Give the '''lab2-check.bash''' file execute permissions (for the file owner).
# Run the shell script and if any warnings, make fixes and re-run shell script until you receive "congratulations" message.
#Arrange proof of the following on the screen:
