#If you notice 0% free space in the / partition, then there is a problem. This most likely is caused by not following steps to create a <u>compressed</u> copy of the VM image. If that is the case, locate the large image backup and remove it. Do NOT remove the image in ''/var/lib/libvirt/images'' directory!

#Then simply type the command '''reboot''' to restart the machine (hopefully in graphical mode).

:NOTE: When you access the system in single-user mode, you can reset passwords for root or other users by using the '''passwd''' command.

::For example:

~~For example~~::*'''passwd root'''::*'''passwd username'''

*'''passwd root''':Not being able to start your c7host due to Kernel Panic or some sort of "catastrophic disk failure" is not as easy to fix. The "worst-case scenario" would be to purchase a new hard disk, perform lab1 completely, perform lab2 to install and set-up virtualization software, then restore your VM image and xml file backups (eg. decompressing images, issuing virsh define commands for xml files). That is why consistently performing backups of ALL of your VMS at the end of each lab is absolutely essential! You have been warned!

*'''passwd username'''
