It starts with a discussion of the hardware requirements for Hyper-V 3.0 and then explains a basic Hyper-V–deployment followed by an upgrade from Hyper-V 2.0 to Hyper-V 3.0. The chapter concludes with a demonstration of migrating virtual machines from Hyper-V 2.0 to Hyper-V 3.0 3 Understanding Hyper-V in Windows Server 2012 Hyper-V 3.0 flavors Before we get started, it is worth noting that like its predecessors, Hyper-V 3.0 comes in two different flavors. Microsoft offers a standalone version of Hyper-V, or you can operate Hyper-V as a server role on top of Windows Server 2012. This book deals with Hyper-V exclusively as a server role. Hardware requirements According to Microsoft, the minimum hardware required for deploying Windows Server 2012 includes: • A 64-bit processor operating at 1.4 GHz or higher • 512 MB of RAM • 32 GB of hard disk space • A DVD Drive • A monitor and video card with a minimum display resolution of 800 x 600 • Keyboard and mouse (or other compatible pointing device) • Internet access Because Hyper-V is designed to use the server’s hardware to host a number of virtual machines, the minimum system requirements are not suitable for Hyper-V. Specifically, you will need more memory and hard disk space, and it’s advisable to have a server with multiple sockets and/or multiple CPU cores. The servers used in the development of this book were equipped with the following: • An 8-core, 64-bit CPU • 32 GB of RAM • A 500-GB hard drive used to store the host operating system. • Four 1-TB hard drives configured as a RAID 5 array In addition to the hardware requirements listed above, the CPU must support hardware-level virtualization. It is worth noting that virtualization has been disabled by default on many servers, so you may need to enable virtualization through the system BIOS, as shown in Figure 1.1. If your server’s BIOS contains a setting for Data Execution Prevention (DEP), you will need to enable that setting as well. 4 Understanding Hyper-V in Windows Server 2012 Figure 1.1 You may need to manually enable virtualization in the server’s BIOS. Installing Windows Server 2012 and Hyper-V 3.0 Setting up a clean installation of Windows Server 2012 and Hyper-V 3.0 is relatively simple and straightforward. First, install Windows Server 2012 by completing these steps: 1. Boot your server from the Windows Server 2012 installation media. 2. When the Windows Server 2012 splash screen launches, verify that the language, time and currency format, and keyboard or input methods are correct (Figure 1.2). Figure 1.2 Verify your installation preferences. 5 Understanding Hyper-V in Windows Server 2012 3. Click Next. 4. Click Install Now (Figure 1.3). Figure 1.3 Click Install Now. 5. Choose the operating system that you want to install (Figure 1.4). It is worth noting that a default Windows Server 2012 does not include the GUI. If you want to use the GUI then do not choose the Server Core option. Although Server Core is Microsoft’s preferred method for deploying Windows Server 2012, it is easier to manage Hyper-V through a GUI. Therefore, the instructions found throughout this book will assume that you are using the GUI. If you are interested in Server Core deployments, see Chapter 5 for a discussion about managing Hyper-V through Windows PowerShell.

Figure 1.5 You must accept Microsoft’s license agreement. 7. When prompted for the type of installation you want to perform, choose the option for Custom: Install Windows Only (advanced) (Figure 1.6). Figure 1.6 Choose the option to perform a custom installation. 8. Choose the volume on which you want to install Windows and click Next (Figure 1.7). 7 Understanding Hyper-V in Windows Server 2012 Figure 1.7 Select the drive or volume on which you want to install Windows Server 2012. 9. Setup will now begin the installation process (Figure 1.8). After the Windows installation completes , you must work through a separate process to install Hyper-V. Figure 1.8 The installation process will now begin. Deploying Hyper-V 3.0 After Windows Server 2012 is up and running, the next step is to install the Hyper-V role. To do so, follow these steps: 1. Open the Server Manager if it is not already open. 2. Choose the Add Roles and Features command from the Manage menu (Figure 1.9). 8 Understanding Hyper-V in Windows Server 2012 Figure 1.9 Choose the Add Roles and Features command. 3. When the Add Roles and Features Wizard launches, click Next to bypass the wizard’s Welcome screen. 4. Click Next. 5. Choose the Role-Based or Feature-Based Installation option (Figure 1.10). Figure 1.10 Choose the Role Based or Feature Based Installation option. 6. Click Next. 7. On the Server Selection screen, make sure that the local server is selected and click Next (Figure 1.11). 9 Understanding Hyper-V in Windows Server 2012 Figure 1.11 Make sure that your local server is selected. 8. Select Hyper-V from the list of server roles (Figure 1.12). Figure 1.12 Select the Hyper-V role. 9. If you are prompted to install additional features, click the Add Features button. 10.
