RED HAT ENTERPRISE VIRTUALIZATION
FOR DESKTOPS
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 oper-
ating 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 hyper-
visor, 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 dual-
core 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.
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®Windows®or Red Hat®Enterprise Linux®
desktops, using either inexpensive thin clients or repur-
posed PCs.
Red Hat Enterprise Virtualization for Desktops is an end-to-
end 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.
