== Virtualization ==
- {{{
+
Virtualization in Fedora Core is based on Xen. Xen 3.0 is integrated within Fedora Core
[[GetVal(DocsDict,BeatsVer)]] in the installer. Refer to
[
http://fedoraproject.org/wiki/Tools/Xen] for more information about Xen.
- }}}
+
== Types of Virtualization ==
- {{{
+
There are several types of virtualization: full virtualization, paravirtualization, and
single kernel image virtualization. Under Fedora Core [[GetVal(DocsDict,BeatsVer)]] using
Xen 3.0, paravirtualization is the most common type. With VM hardware, it is also possible
to implement full virtualization.

=== Benefits of Paravirtualization ===
- *Allows low overhead virtualization of system resources.
- *Can provide direct hardware access in special cases (e.g., dedicated NICs for each
guest OS).
- *Allows hypervisor-assisted security mechanisms for guest OS.

== Installing Xen, Configuring and Using Xen ==
+
Xen must be installed on the host OS and the host OS must be booted into the Hypervisor
Kernel. Fedora Core [[GetVal(DocsDict,BeatsVer)]] includes an installation program for the
guest OS that will use an existing installation tree of a paravirtualized-enabled OS to
access that OS's existing installation program. Currently, Fedora Core
[[GetVal(DocsDict,BeatsVer)]] is the only available paravirtualized-enabled guest OS.
Other OSs can be installed using existing images, but not through the OS's native
installation program.
