Virtualization

Direct support for server virtualization, in the form of the Hyper-V hypervisor, was one of the
most important and highly anticipated improvements in Windows Server 2008. With the release
of Windows Server 2008 R2, Microsoft extends Hyper-V virtualization to include support
for client desktop virtualization, and adds important new capabilities for dynamic disk allocation,
live migration, and improved scalability and redundancy. We cover the improvements in
Hyper-V server virtualization capabilities in Chapter 3, “Hyper-V: Scaling and Migrating Virtual
Machines.”
Virtualization, however, isn’t limited to machine virtualization, but also includes presentation
virtualization (RDS), application virtualization (App-V), and client desktop virtualization
(VDI).
Windows Server 2008 R2 adds improvements in RDS that provide a more seamless integration
with Windows 7 clients, including full support for Windows Aero and multiple monitors.
Application virtualization support in R2 is improved, and the addition of the Remote Desktop
Virtualization Host (RD Virtualization Host) role service enables full desktop virtualization.
