{|cellpadding="8" width="100%"|- valign="top"| '''In this lab, you will create three virtual machines'''. This also gives you an opportunity to experiment with different ways of installing Fedora. Later in this course you will install another operating system distribution in a virtual machinesmachine.  You should already have both a '''Fedora installation DVD''' and a '''Fedora LIVE CD'''.

* '''Boot MediaIn both cases, the boot media (which you used to load the installation software) and the installation source (the software that got installed) were the same:'''** your CD or /DVD** Hard disk** USB flash drive** Network provides both. However, the Fedora (and most other Linux distributions) permits you to use any combination of bootmedia and installation media:

The virtual machine is running from the live disc at this point, and no software has been installed on the ''hard drive'' of the virtual machine.# Login to the VM and double-click on the ''Install to Hard Drive'' icon. The installation program, similar to the one used when installing Fedora questions in Lab 2, will appear. You will get a warning at one point during the installation process that the disk "may need to be re-initialized" -- this is simply a warning that the virtual disk is completely blank, and it is safe to select ''Re-initialize drive''.# During the installation process, when prompted for the drive, select "Virtio Block Device", when prompted for the hostname, enter "fedora1", when prompted for the timezone, select ''America/Toronto'', and when asked about storage, select ''Use All Space''. '''Use the default values for all other fields.'''
