Investigation 1: Installing from a Live Disc
== Investigation 1: Installing from a Live Disc ==
{{Admon/tip|Using an Image instead of a Live Disc|It is recommended that you perform this installation from your Fedora LIVE CD. As a matter of interest (for future reference), it is possible to download the .iso image file from http://belmont.senecac.on.ca/fedora/releases/16/Live/x86_64/Fedora-16-x86_64-Live.iso and install directly from that file. There are many Internet tutorials that show the individual how to perform that task.}} ==== Introduction ==== In this investigation, you will install Fedora from your live disc, and observe the differences between this type of installation and the DVD installation previously performed. ==== VM Details ====
* '''Name:''' fedora1
* '''Boot media:''' Fedora Live CD
* '''Installation source:''' Network server: http://belmont.senecac.on.ca/fedora/releases/16/Fedora Live CD/x86_64/os/* '''Kickstart file:''' http://zenit.senecac.on.ca/~chris.tyler/fedora16-vda-ks.cfg
* '''Memory:''' 768MB
* '''Disk space:''' 10GB
* '''CPUs:''' 1

There are five steps to be completed; click Forward after each step:# '''Step 1 of 5:''' Enter the virtual machine (called '''fedora1''') name and select '''Local install media''' (refer to ''Step 1 of 5'' thumbnail above).# '''Step 2 of 5:''' '''Insert the CDROM or DVD containing the Fedora Live Disc image. Wait a moment for the disc to be recognized''', then select '''Use CDROM or DVD''' as the install media. Set the ''OS type'' to '''Linux''' and the ''Version'' to '''Fedora 16''' (refer to ''Step 2 of 5'' thumbnail above).<!-- {{Admon/tip|Using an ISO image|Instead of using a physical CD or DVD, you can use an ISO image of a CD or DVD. The virtualization software will make this ISO image appear like an actual CD within the virtual machine. Because hard disks are faster then optical discs, this will work faster than an actual CD/DVD.}}{{Admon/note|Choosing the operating system type and version|The purpose of the ''OS type'' and ''Version'' fields is to fine-tune some of the virtual machine settings for best performance. The VM will work even if these are set incorrectly.}} --># '''Step 3 of 5:''' Set the memory to '''768 MB''' and the number of CPUs to '''1''' (refer to ''Step 3 of 5'' thumbnail above).# '''Step 4 of 5:''' This next step creates a disk file that will be used to simulate the virtual machine's disk drive. Select a size of '''10 GB''' and checkmark the box labeled '''Allocate entire disk now''' (refer to ''Step 4 of 5'' thumbnail above).# '''Step 5 of 5:''' Review the options that you have selected. '''Make a note of the storage location.''' If anything needs to be changed, use the ''Back'' button to go back and edit it; otherwise, click '''Finish''' (refer to ''Step 5 of 5'' thumbnail above). {{Admon/caution|Removing and Recreating VMs|If for some reason the user wants to remove a Virtual Machine, they can right-click the VM, and select delete in the Virtual Machine Manager. It is recommended to '''"delete the image file" in the remove VM dialog box when removing and then recreating a VM'''. Note: If you fail to properly remove the VM image file, it may affect the hard disk size for the new VM (i.e. use the old smaller size. Make certain to remove that VM image file prior to recreating the VM.|'''}}  {{Admon/note|Fedora LIVE CD Install Screen Shots Thumbnails|While performing the Fedora 16 LIVE CD install, click on the thumbnails below to provide a '''"visual reference"''' while performing this particular Fedora installation.}} {|cellpaddingPerform ="8" width="100%" |[[Image:fedoralive1.png|thumb|100px| The Virtual Machine will now start.]]|[[Image:failedtoload.png|thumb|140px| '''Ignore and close the "Failed To Load" dialog box'''.
