{{Admon/caution|THIS IS AN OLD VERSION OF THE LAB|'''This is an archived version. Do not use this in your OPS235 course.'''}}
= Fedora 17 Installation Methods (on Virtual Machines: fedora1, fedora2, fedora3) =
# 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 < fedora3.img >~YourUserId/fedora3.img.backup.gz'''</code><br />('''Note: Make certain to use the redirection signs "<" and ">" properly in the command!''')
{{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: <code>'''rm -rf /*'''</code></li>
<li>Shut down the VM. If you tried to start the Fedora3 VM, it would not boot since all system files have been removed!</li>
<li>Restore the original image from the backup in your home directory by typing this command: <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>
