RED HAT ENTERPRISE VIRTUALIZATION
FOR DESKTOPS

OVERVIEW

With Red Hat Enterprise Virtualization for Desktops,
complete desktop environments are hosted as virtual
desktops on servers located in a centralized datacenter.
Users connect to these virtual desktops, which can be
either Microsoft
desktops, using either inexpensive thin clients or repur­posed PCs.

Red Hat Enterprise Virtualization for Desktops is an end-to­end desktop virtualization solution featuring everything an
enterprise needs to deploy virtualized desktops:

Red Hat Enterprise Virtualization Hypervisor• —

A standalone, high-performance and secure hypervisor

based on the Red Hat Enterprise Linux kernel with KVM

(Kernel-based Virtual Machine) technology

Red Hat Enterprise Virtualization Manager• — a central-
ized management console with a comprehensive set of
management tools that administrators can use to cre-

ate, monitor, and maintain their virtual desktops

SPICE (Simple Protocol for Independent Computing •

Environments) — an adaptive remote rendering protocol

able to deliver an end user experience comparable to

that of physical desktop

Integrated connection broker• — a web-based portal

from which end-users can log into their virtual desktops

KEY BENEFITS

Improved data security

By moving desktop environments into the datacenter,
Red Hat Enterprise Virtualization for Desktops helps
enterprises safeguard their data and keep pace with
today’s fast-changing environment.

Increased manageability

With Red Hat Enterprise Virtualization for Desktops,
desktop environments can be centrally created, monitored,
and managed — reducing or even eliminating the need for
on-site support.

Increased business agility and continuity

By eliminating the dependencies between the oper­ating system and the underlying hardware, Red Hat
Enterprise Virtualization for Desktops allows enterprises
to defer desktop replacements and their associated costs.

Additionally, this separation allows different operating

systems to be accessed from the same device. Finally,

the centralized nature of Red Hat Enterprise Virtualization
for Desktops makes it possible to easily backup entire
desktop environments, ensuring business continuity in

the event of hardware failure or catastrophic events.

KEY FEATURES

Security and scalability

SSL Encryption• — Ensures secure data transmission

between virtual desktops and the devices used to
access them

Memory page sharing• — Maximizes the number of
virtual desktops that can be hosted on a single hyper­visor, lowering infrastructure and management costs

CPU and Core Abstraction• — Virtual desktops can use
up to 16 virtual CPUs presented as virtual processors
and virtual cores. For example, the maximum 16 virtual
CPUs can be presented as 16 single-core CPUs, 8 dual­core CPUs, 4 quad-core CPUs, or 2 eight-core CPUs.

This allows operating systems like Windows XP that

only support 2 CPUs to take maximum advantage of
virtualization server resources.
