Virtualization is a broad computing term for running software, usually operating systems, concurrently and isolated from other programs on one system. Virtualization uses a hypervisor, a software layer that controls hardware and provides guest operating systems with access to underlying hardware. The hypervisor allows multiple operating systems to run on the same physical system by giving the guest operating system virtualized hardware.

You can install Red Hat Enterprise Linux 6 as a fully virtualized guest on a 64-bit x86 host system or in a logical partition (LPAR) on a POWER or IBM System z system.

For more information about installing Red Hat Enterprise Linux 6 in a virtualized environment on a 64-bit x86 host system, refer to "Part II. Installation" in the Red Hat Enterprise Linux 6 Virtualization Guide, available from http://docs.huihoo.com/redhat/. For more information about installing Red Hat Enterprise Linux 6 in a virtualized environment under PowerVM on IBM System p, refer to PowerVM Virtualization on IBM System p: Introduction and Configuration, available from http://publib-b.boulder.ibm.com/abstracts/sg247940.html. For more information about installing Red Hat Enterprise Linux 6 in a virtualized environment under z/VM on System z, refer to Part III, “IBM System z Architecture - Installation and Booting” in this guide.
