→Investigation 6: How do I backup a virtual machine?
# Shut down all of the virtual machines.
# Change to the directory <code>/var/lib/libvirt/images/</code>. Note the size of the files in this directory. What do these files contain?
# Make a compressed backup of the <code>fedora3.img</code> file to your home directory with this command: <code>gzip </var/lib/libvirt/images/fedora3.img >~'''YourUserId'''/fedora3.img.backup.gz</code>
{{Admon/caution|Make sure the backup is successful!|If there are any error messages, '''DO NOT''' proceed past this point. You're going to destroy your fedora3 virtual machine and restore it using the backup you have created -- if there are any problems with the backup, you will not have a working virtual machine, and will have to re-install it.}}
<ol>
<li>Wreck <u>only</u> your fedora 3 system! Try this command inside the fedora3 virtual machine ('''DO NOT''' do this on your main Fedora system, or you will have to repeat your '''lab2''' and portions of your '''lab3'''!): <code>rm -rf /*</code></li>
<li>Shut down the VM.</li>
<li>Restore the original image from the backup in your home directory (type this command carefully): <code>gunzip <~'''YourUserId'''/fedora3.img.backup.gz >fedora3.img</code></li>
<li>Restart the VM. Is it working normally?</li>
<li>Create compressed backups of your other virtual machines.</li>
