Chapter 23:
Introduction to Virtualization
Ubuntu is not yet "installed" into the virtual machine. The live CD version is
instead running purely from the virtual CD-ROM. Accordingly, any files you create,
applications you install, or changes you make to Ubuntu will not be saved. In order
to make the virtual machine contain a fully functioning copy of Ubuntu, you need to
run the Ubuntu installation process. On the live CD desktop is a shortcut called Install.
Double-clicking it will begin the Ubuntu installation procedure. The detailed Ubuntu
installation procedure is not covered here, but it is similar to the installation of Fedora
Linux, which was discussed in Chapter 20.
NOTE
When you install a guest operating system into a virtual machine, it's just like installing it
onto a bare-metal computer. You will need to partition and format the hard disk for the virtual machine
during its installation, because the virtual hard disk starts out completely blank. The first time you
install a guest operating system into a virtual machine, you might be concerned that all of the typical
warnings about deleting the hard disk's contents might possibly affect the host computer. However,
as long as you're running in the virtual machine, only the virtual hard disk can be partitioned and
formatted by the guest operating system; your host system is completely insulated from the virtual
machine.
