In
today??™s server computing model, often an entire server is devoted to running a particular
application that may be tied to a particular operating system. As a result, the entire computer
may be underutilized if it is not a high-demand application.

Running Fedora and Red Hat Enterprise Linux 8
FIGURE 8-2
Fedora includes the GNOME or KDE desktop, and many games.
With virtualization, you have the opportunity to run multiple instances, including an
entire operating system, an application, and a data combination. Those instances (called
guests) can be Linux, Windows, or any other operating system that runs on the computer
hardware. Guests operate separately from each other, and so remain secure from each
other. As demand slows or increases for a guest, it can be moved to different hardware to
make the best use of available hardware.
Red Hat, Inc. has thrown some strong development support into the Xen virtualization
software (www.xensource.com) that is included in Fedora 8. Tools for starting, stopping,
and otherwise managing multiple guest operating systems are all included in the
Xen version that comes with Fedora 8.
AIGLX desktop eye candy??”The Accelerated Indirect GLX (AIGLX) project is a cooperative
effort between the Fedora community and the X.
