#Press the down arrow key to highlight: and press e to edit the Linux Kernel boot options.#At the end of the command line, add a space (after the word quiet) and type single (i.e. for single user mode).#Press ENTER to save editing changes to the Linux Kernel Image boot command.#Press '''b''' to boot from that modified Linux Kernel Image.#The system should boot up in text-based mode, and when completed be in the root's home directory (without prompting for root's password!)#One thing to look at is partition space usage. Issue the command: '''df -h'''#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).
