# A window will appear with the title ''New VM''. There are five steps to be completed; click Forward after each step:
# '''Step 1 of 5:'''Select '''Local install media''' and click '''Forward'''.
# '''Step 2 of 5:''' Select '''Use ISO Image''', click the '''Browse''' button, and then the '''Browse Local''' button. Navigate to the location of the downloaded Centos7 LIVE CD image, select the image file and click '''Open'''. When finished, click Forward to proceed. If an error message appears regarding search permissions, just click '''yes''' to proceed.<br><br>'''NOTE:''' Select from the installation menu '''Troubleshooting''' and then select '''Install in Basic Graphics Mode'''.<br><br>
# '''Step 3 of 5:''' Set the memory to '''2048 MB''' and the number of CPUs to '''1'''
[[Image:vm-path.png|thumb|right|300px|It is extremely important to '''correctly specify the VM image file path-name'''. Double-check the spelling of the path-name before proceeding!]]
# Take a look at the kickstart file (eg. view url in a webj-browser) to determine the root password as well as the name and password for the first user account!
# Boot the virtual machine and log in (use the user ID and password information from the previous step). Compare the experience to the first time you booted the other virtual machines. Record this information in the '''table contained in Investigation 4'''.
# Repeat the steps as you did to '''start the SSH service''', '''set iptables to accept connections via ssh''', '''test connections between centos3 and c7host''', and '''disable SELinux''' (refer to lab1).
# Remember that centos3 is text-based interface only (no graphics). To recover from a blank screen, press a key (like the SPACE key) to return to the screen display.
# Record the time taken to install, and compare this to the time taken by the previous installations. Record your findings in the Installation Comparison chart in lab2 logbook.

::* In order to fully back up a virtual machine, what information should be saved in addition to the virtual machine image?
