Part 1: Backing Up Virtual Machines
# We will now learn how to download a compressed image file and xml configuration file and add it as a VM to the virtual manager menu.
# Issue the following commands:<ul><li><b><code><span style="color:#3366CC;font-size:1.2em;">wget</span></code></b></li><li><b><code><span style="color:#3366CC;font-size:1.2em;">wget</span></code></b><br><br></li></ul>
<ol><li value="17">The downloaded file "practical1.img.gz" is a "raw image compressed VM file", but will work the same for a Virtual Machine as the qcow2 file format.Copy these files to the '''/var/lib/libvirt/images''' directory and decompress that raw 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 practical1.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> Launch the VM Prior to see if it boots-up</li><li>Can your practical test, you log into this will be required to perform a similar operation to download, unzip and run a VM? Perhaps image for your instructor will give you a clue in week #7..practical test. >;p<br><br></li></ol>
