Chapter 3 Summary • LO 3. 1 Virtualization – There are many types of virtualization today, such as virtual worlds, storage virtualization, network virtualization, server virtualization, and desktop virtualization—the subject of this chapter. 41 © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved.

Chapter 3 Summary – Virtualization had its roots in the dumb terminal mainframe systems of the 1960 s and the terminal service-terminal client systems of the 1990 s – Today’s virtual desktops can be hosted on network servers or on PCs. – A hypervisor, or virtual machine monitor (VMM), is the software that emulates the necessary hardware on which an operating system runs. 42 © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved.

Chapter 3 Summary – A Type I hypervisor (a “bare-metal hypervisor”) runs directly on a computer without an underlying host operating system. – A Type II hypervisor requires a host operating system. – The major sources of hypervisors are Citrix, VMware, Parallels, Microsoft, and Oracle. 43 © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved.

Chapter 3 Summary • LO 3. 2 Desktop VMs on Windows Desktops – There are both commercial and free Type II hypervisors for running Linux, DOS, or Windows on a Windows desktop computer. – Microsoft Virtual PC 2007 is free and will run on any computer running Windows XP or newer versions of Windows, and it supports Windows, Linux, and DOS guests without requiring hardware-assisted virtualization. 44 © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved.

Chapter 3 Summary – Windows XP Mode is a free hypervisor that installs on a Windows 7 host with a Windows XP guest preinstalled. It does not require hardwareassisted virtualization. – The free Windows Virtual PC requires both Windows 7 and hardware-assisted virtualization. Use the Hardware-Assisted Virtualization Detection Tool to test your computer before you download one of these solutions. 45 © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved.

Chapter 3 Summary – VMware has several commercial hypervisor products. Download and install the trial version of VMware player to temporarily test this product before buying it. – Oracle Virtual. Box is free and runs on several hosts including versions of Windows, Linux, and Mac OS X. It will run on hardware that does not support virtualization. 46 © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved.

Chapter 3 Summary • LO 3. 2 Desktop VMs on Mac OS X – You have several choices for hypervisors for Mac OS X that will run versions of Windows and Linux. – Apple Boot Camp is not actually a hypervisor so much as a dual boot option that allows you to dual -boot between Mac OS X and Windows. This gives each OS full use of the hardware, but only one can be loaded at a time. 47 © 2012 The Mc. Graw-Hill Companies, Inc. All rights reserved.

Chapter 3 Summary – Oracle Virtual. Box is a free hypervisor and will run versions of Windows, Linux, and DOS on hardware that does not support virtualization. – Parallels is a commercial hypervisor product for Apple and other hosts, mentioned, but not detailed in this chapter. 48 © 2012 The Mc.
