What is Server Virtualization?
• Concept of virtualization has existed in various forms in computing since the early 1960s
• In virtualization, physical resources are abstracted and shared by multiple operating systems
16© 2008 Citrix Systems, Inc. — All rights reserved
The Case for Server Virtualisation
• Servers are costly to maintain• Costs encompass provisioning, housing, power, cooling, management,
etc.
• Servers are poorly utilized• Typically one workload per server
• Physical servers are inflexible• More complex management than desktops

• Division founded by Xen creators in 2005 as XenSource, Inc.• Leaders of the Xen project
• Acquired by Citrix Systems – Oct. 2007
• Home of the Xen hypervisor• Open source, next-generation architecture
• High-performance, bare metal virtualization
• Delivers commercial virtualization products• Commercially packaged and supported Xen virtualization platform
for Windows and Linux - Citrix XenServer

Paravirtualisation
• Relies on “enlightened” operating systems
• Kernel and I/O paths know they are being virtualized
• Cooperation provides best performance
