Red Hat Integrated Virtualization - A Quick Guide

Overview

This paper shows examples of Red Hat's integrated virtualization being used to reduce costs, and improve availability, security and flexibility. There are two styles of virtualization employed by Red Hat Enterprise Linux. One is called "paravirtualization" and the other is named "HVM". HVM or "Hardware Virtual Machine" takes advantage of the latest Intel and AMD hardware assistance. This technique allows Red Hat Enterprise Linux to emulate a complete ia32 or ia32-64 architecture and enables the operation of any operating environment designed for those architectures. "Paravirtualization" is a highly optimized virtualization technique and only Red Hat Enterprise Linux version 5 and Red Hat Enterprise Linux version 4 Update 5 are able to operate in this way.
