# Issue the following commands:<ul><li><b><code><span style="color:#3366CC;font-size:1.2em;">wget http://cs.senecacollege.ca/~ops235/lab2/centos4.qcow2.backup.gz</span></code></b></li><li><b><code><span style="color:#3366CC;font-size:1.2em;">wget http://cs.senecacollege.ca/~ops235/lab2/centos4.xml</span></code></b></li></ul>
