Step-by-Step 3.01 Desktop VMs on Windows Desktops Installing Microsoft Virtual PC 2007
Desktop VMs on Windows Desktops • Microsoft Virtual PC 2007 (cont.) • Creating a Virtual Machine in Virtual PC • Start Virtual PC 2007 from Start | All Programs • New Virtual Machine Wizard • Create a customized VM • Create a VM with the defaults for the client • Add a pre-existing VM • Start VM with distribution disc in drive
Desktop VMs on Windows Desktops • Windows XP Mode and Windows Virtual PC • Windows XP Mode for Windows 7 • Windows Virtual PC with Windows XP preinstalled • Use to run legacy applications
Desktop VMs on Windows Desktops • Windows Virtual PC for Windows 7 • Guest OSs • Windows Vista • Windows 2000 • Linux • Requires hardware-assisted virtualization • Use the Hardware-Assisted Virtualization Detection Tool
Desktop VMs on Windows Desktops • VMware Player • VMware has produced VM software for 10 years+ • VMware Player is a desktop hypervisor • Available as a free trial • Three versions • 32-bit/64-bit for Windows hosts • 32-bit for Linux hosts • 64-bit for Linux hosts
Figure 3-9 Download the trial version of VMware to test it before deciding to buy it
Desktop VMs on Windows Desktops • Oracle VirtualBox • Host OSs • Windows • Linux • Mac OS X • Client OSs • Windows • Linux • DOS • Does not require virtualization hardware
Desktop VMs on Mac OS X • Apple Boot Camp • Not really a virtualization option • Multi-boot between Mac OSX and Windows • Requirements • Intel-based Mac • Mac OS X 10.6 or later strongly recommended • Keyboard and point device • Built-in optical disk drive or compatible external drive • Mac OS X installation disc
Desktop VMs on Mac OS X • Apple Boot Camp (cont.) • Requirements • Intel-based Mac • Mac OS X 10.6 or later strongly recommended • Keyboard and point device • Built-in optical disk drive or compatible external drive • Mac OS X installation disc • Client OSs • Windows XP Home or Professional Edition with SP 2 • Windows Vista or Windows 7 Home Premium, Professional, or Ultimate
Desktop VMs on Mac OS X • Apple Boot Camp (cont.) • Boot Camp comes with Mac OS X • Run Boot Camp Assistant • From Applications | Utilities folder • Creates a new partition for the Windows OS

The Boot Camp partition appears with other drives under Devices in the Finder
Desktop VMs on Mac OS X • Oracle Virtual Box • Guests • Windows • Linux • DOS • Hardware virtualization not required • Download disk image file • Install VirtualBox from the disk image
Step-by-Step 3.02 Installing Oracle VirtualBox
Desktop VMs on Mac OS X • Oracle Virtual Box (Continued) • Install Guest Additions after installing OS • Improves client OS appearance • Enables improved drivers for other hardware

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.
Chapter 3 Summary • Virtualization had its roots in the dumb terminal mainframe systems of the 1960s and the terminal service-terminal client systems of the 1990s • 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.
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.
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.
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 hardware-assisted 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.
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 VirtualBox 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.
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.
Chapter 3 Summary • Oracle VirtualBox 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.
