# 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><br><br></li></ul>
<ol><li value="17"># Copy these files to the '''/var/lib/libvirt/images''' directory and decompress the qcow2 image file.</li><li># Make certain your present working directory is: '''/var/lib/libvirt/images'''</li><li># Issue the command: <b><code><span style="color:#3366CC;font-size:1.2em;">virsh define centos4.xml</span></code></b></li><li># What happened in the virtual manager window? To remove a VM entry in the Virtual Manager window, simply issue the command: '''virsh undefine vm_name''' (without the '''.xml''' file extension)</li><li># Start up your new centos4 VM.# Click on the user OPS235, and click the cog icon.# Notice Cinnamon (Software Rendering) is selected. The Cinnamon desktop environment has been installed on this VM. From this menu, you can select other installed desktop environments. This is how you switch between them.
