ADVANCED SERVER VIRTUALIZATION VMware and Microsoft Platforms in the Virtual Data center phần 3 doc

124  Advanced Server Virtualization Disk Disk space and performance are as critical as processor and memory in its direct impact on guest virtual machine performance.  e Microsoft recommendation of 2GB of available hard disk space does not take into account the disk space requirements of the virtual machines. As discussed in chapter 7, the proper way to size and evaluate hard disk subsystems is to provide adequate performance under varying loads. Bear in mind that when virtual machines are launched, they will consume additional physical hard disk space beyond just that of their virtual hard disk fi le. With the release of Vir- tual Server 2005 R2, a blank saved state fi le (.VSV) is created when the virtual machine is launched.  is fi le is the size of the memory being used by the running virtual machine. So, if you have a virtual ma- chine that has 512MB of memory reserved for it, an extra 512MB fi le will be created on the host’s physical disk.  is will consume disk space that may not have been accounted for in your initial planning. Prior to the release of R2, this fi le would only be created when someone attempted to save state the virtual machine. With a pre-created saved state fi le in place during the launch of a virtual machine, Microsoft could better guarantee that the user would be able to save the state of a virtual machine rather than fi nd out when it is too late that the host server does not have enough disk space to accommodate the action. Network Microsoft host operating systems do not require permanent network connectiv- ity, however to perform any useful functions there should be one or more net- work cards present to deliver proper server class functionality.  e specifi c details and options of the recommended confi gurations are provided in chapter 7. Display  e minimum required graphics display card must provide at least 800×600 resolution and 256 colors. Although this is not recommended, as it will be near- ly impossible to administer the physical host server at such a low resolution and color depth. For the best performance, a graphics display card providing at least 1024×768 resolution and 16.7 million colors should be used.  is will also allow for easy administration of virtual machines from their physical host if necessary.

Windows Server 2003 Standard off ers support for up to four physical processors and 4GB of memory, Win- dows Server 2003 Enterprise supports up to eight physical processors and 32GB of memory, and Windows Server 2003 Data Center supports up to thirty-two physical processors and 64GB of memory.  ere are only a few instances when it would make sense to run Virtual Server on anything beyond Windows Server 2003 Enterprise Edition due to the high cost of hardware and software for a Data Center Edition class of machine. Virtual Server Administration Interface Virtual Server’s administration is done through a Web-based interface that re- quires Microsoft Internet Information Services (IIS) version 6.0. Only Microsoft Internet Explorer is supported as a browsing interface into the administration site and for full functionality, ActiveX Controls must be enabled. Virtual Server Scripting Microsoft has included a COM API scripting interface for automating the con- trol and management of virtual machines.  e COM API will be fully explored in chapter 25. Summary Microsoft Virtual Server 2005 is a new platform that is maturing rapidly.  ere are several capabilities that are lacking when compared to some of the more mature virtualization platforms, however the licensing costs easily make up for this short coming. Because Virtual Server leverages the Microsoft Windows Server 2003 family of operating systems as its platform, it gains the ability to support the broadest number of hardware platforms of any virtualization plat- form (matching that of VMware’s GSX server for Windows, which leverages the Windows operating systems as well). Support for guest operating systems is currently limited to Microsoft only-based platforms, but with the introduction of Virtual Server 2005 R2 the support will ultimately expand to include Linux and other non-Microsoft-based operating systems. Licensing is simply based on the number of processors that are going to be used, either a maximum of four or Marshall_AU3931_C008.indd 125Marshall_AU3931_C008.indd 125 4/13/2006 11:31:12 AM4/13/2006 11:31:12 AM 126  Advanced Server Virtualization thirty-two. Hardware and software requirements are simply any server that runs and can support Microsoft Windows Server 2003 Standard Edition or greater. It is recommended that the server being used be upgraded if it was not originally ordered with specifi cations for the specifi c purpose of providing virtualization services.

All options and aspects of the installation are covered in this chapter, allowing the reader to understand each option along with the ramifi cations of that option before doing an actual install.  e instal- lation of the Standard Edition is identical to the installation of the Enterprise Edition.  is chapter may also be used as a reference during the planning of the installation to ensure a repeatable and stable platform where the desired capabili- ties are consistently delivered. Virtual Server 2005 R2 Requirements Before installing Microsoft Virtual Server R2, it is important to make sure that your server and operating system meet all of the requirements. If a previous version (such as a beta or evaluation copy) is installed, it should be completely removed before installing a newer version. Before uninstalling a previous version of Microsoft Virtual Server, the Virtual Server service should fi rst be stopped and then the Add/Remove Program Files under Control Panel can be used to select the previous version of Microsoft Virtual Server and uninstalled by click- ing the Remove button.  is will uninstall the previous version of Microsoft Virtual Server. Marshall_AU3931_C009.indd 127Marshall_AU3931_C009.indd 127 3/31/2006 11:17:26 AM3/31/2006 11:17:26 AM 128  Advanced Server Virtualization When installing Virtual Server, the local administrator or a local user’s ac- count with administrative privileges must be used. Virtual Server should only be installed for production use on a Windows Server 2003-based operating system, however it will install on a Windows XP Professional with SP2 host operating system for non-production use. Preparing the Host Server Preparing the server is the fi rst in a critical series of steps ensuring that the system will be stable and provide adequate performance.  Ensure the server is properly cabled with the necessary power cables. Dual power supplies connected to separate power leads is preferred.  Connect any KVM type solution to the host server for remote manage- ment.  Connect all Ethernet ports that will be used (unused ports can also be con- nected if desired).  Upgrade to Gigabit Ethernet, if possible.  Team multiple network adapters for best performance.  Download and install the latest BIOS and then confi gure its settings ap- propriately.  Download and upgrade any fi rmware that needs to be updated.  Confi gure the RAID controller. 1. Confi gure the RAID controller for optimized write operations. 2. A multi-channel controller card should be confi gured with one channel confi gured as a mirrored pair for the operating system and the other channel confi gured as RAID 5 with four or more drives in the RAID set if possible for the virtual machines. 3.  e default stripe size is acceptable. 4. Assign physical hard drives. 5. Create logical volumes.  Delete all existing partitions including any server manufacturer's support partition.  Format using a high-performance fi le system such as NTFS.  Install and confi gure the host operating system. Preparing the Host Operating System  e host operating system is the next critical step in building the proper plat- form for Virtual Server.  e detailed steps involved in installing the host op- erating system will not be covered in this book. It is assumed that a basic level of understanding and experience with installing a Windows operating system Marshall_AU3931_C009.indd 128Marshall_AU3931_C009.indd 128 3/31/2006 11:17:32 AM3/31/2006 11:17:32 AM The Microsoft Virtual Server Platform  129 already exists.  e proper confi guration is covered below, including all required options and steps.  Microsoft Internet Information Server (IIS) 5.1 or 6 World Wide Web Services must be installed and the services must be started and operating without errors.  Ensure that the Physical Address Edition (/PAE) option is set in the boot. ini fi le if greater than 4GB of memory is being used.  Confi rm the correct amount of memory is being reported by the host op- erating system.  Ensure that the paging fi le is of adequate size.  Stop any unnecessary services.  Install only the necessary packages and applications rather than loading down the host operating system. It should only serve as the virtualization platform.  Disable all protocols and services on any network adapters that will be used exclusively by virtual machines, including TCP/IP. After the instal- lation, ensure that Virtual Machine Network Services is enabled on these network adapters.  Defragment the host operating system's hard disk.  Clear all event logs in Event Viewer.  Set the system's advanced performance settings for the processor to be optimized for background services.  Set any antivirus software to skip scanning of virtualization confi guration fi les, virtual hard disk image fi les, fl oppy image fi les, and CD/DVD-ROM ISO image fi les. Additionally, real-time scanning should be disabled en- tirely and scanning should be scheduled for nightly scans instead. Installing Microsoft Virtual Server 2005 R2 Microsoft Virtual Server 2005 R2 uses a Microsoft Windows Installer-based installation Wizard much like other current Microsoft applications.  e instal- lation Wizard is straight-forward and is very consistent with other Microsoft application installation Wizards.  is section provides step-by-step installation instructions together with screenshots that clearly show each available option. In this example, Microsoft Virtual Server 2005 R2 Enterprise Edition will be in- stalled on a host server running Microsoft Windows Server 2003 R2 Enterprise Edition.  e installation media for Microsoft Virtual Server 2005 R2 is a single ex- ecutable setup fi le.  is setup fi le should be copied onto the host server and then executed. Once the setup fi le has been started, the installation process will begin.

To continue the installation, the button labeled Install Microsoft Virtual Server 2005 R2 must be clicked. Figure 9.1 Microsoft Virtual Server 2005 R2 Setup Menu. Figure 9.2 License Agree- ment.  e license agreement is displayed on the next screen (see Figure 9.2) of the Wizard. It must be read and accepted before the installation process can con- tinue.  e option labeled, “I accept the terms in the license agreement,” must be Marshall_AU3931_C009.indd 130Marshall_AU3931_C009.indd 130 3/31/2006 11:17:32 AM3/31/2006 11:17:32 AM The Microsoft Virtual Server Platform  131 selected before the Next button is enabled. Once the license agreement has been accepted, the Next button is clicked.  e Customer Information screen has three input fi elds that must be fi lled out as shown in Figure 9.3.  e User Name fi eld requires the name of the licensed owner of the software and the Organization fi eld is used to optionally input an organization name of the user.  e Product Key fi eld requires the entry of a valid Microsoft Virtual Server 2005 R2 serial number. Once these fi elds are fi lled out properly, the Next button must be clicked to continue the installation.  e Setup Type screen is displayed next and it provides a decision point for the installation. Either the Complete or the Custom option must be selected.  e Complete option installs all options and reduces the number of installation Wizard screens presented (see Figure 9.4). It is also the default option.  e Cus- tom setup type allows exact features to be installed as required (see Figure 9.5). If the Custom option is selected, extra Wizard screens will be presented in order for the Custom installation features to be selected or deselected as required. Af- ter a setup type is selected, the Next button is clicked to proceed. Figure 9.3 Customer Information. Figure 9.4 Setup Type, Complete Installation.

After all Custom installation options have been selected, the Next button on the Custom Setup screen is clicked to continue the installation.  e next set of installer screens are displayed for if either the Complete or Custom setup type was used.  ere are two screens named Confi gure Compo- nents.  e fi rst Confi gure Components screen allows the confi guration of the TCP port that will be confi gured for the Virtual Server Administration Website as shown in Figure 9.9. By default, the value is port 1024. In this example, the default value is used. Additionally, this screen also has an option to select the user account context under which the Administration Website will reside.  e default option (used in this example) is to run the Administration Website as the authenticated user.  e other available option is to run the Administration Figure 9.7 Select Destina- tion Folder.
