Citrix XenDesktop™ Technology Preview Kit Citrix XenDesktop™ Technology Preview Kit Getting Started Guide Introduction The Citrix XenDesktop Tech Preview Kit includes the key components needed for a complete desktop delivery system. With the Tech Preview Kit, you get an early look at how these integrated technologies simplify desktop operations and provide the best user experience at the lowest cost of ownership. Included in the Tech Preview Kit: • • Citrix XenServer – An enterprise-class virtualization solution that creates the foundation for virtual desktop infrastructure (VDI) and offers advanced management features. Citrix XenDesktop Server – High speed delivery technologies that connect office workers to their personalized desktops with best performance, ease of use and rich desktop experience. To implement a XenDesktop Tech Preview Kit environment Implementation of the XenDesktop Tech Preview Kit consists of three steps: 1. 2. Build desktop virtualization infrastructure – This step includes the installation and configuration of XenServer and the creation of XenServer Virtual Machines (VMs.) Configure desktop delivery controller – This step covers the installation and configuration of XenDesktop Server. Preferably, XenDesktop Server should be installed in your XenServer virtualization environment on a virtual machine Server image. Deliver virtual desktops – This step covers the integration of the components to provide desktops to your users. 3. 2 Citrix Desktop Server, Version 2.0 Recommended Deployment System Requirements This topic describes the high-level requirements for installing the XenDesktop Tech Preview Kit. For further details regarding requirements refer to each component’s product documentation. Requirements for XenDesktop Tech Preview Kit Due to the requirements of the XenDesktop Tech Preview Kit it is strongly recommended to install this environment separately and in isolation away from your production network environment. All components except XenServer components should be installed on virtual machine images within the XenServer virtualization infrastructure but can be installed on separate physical machines based on your available hardware. • Windows 2003 Active Directory in Native mode. o For the XenDesktop Tech Preview Kit you will need an Active Directory Domain in Native mode consisting of 1 Domain Controller. Multiple Domain Controllers are not supported by the XenDesktop Tech Preview Kit. XenDesktop Server 2.0 uses Active Directory extensively to store configuration information and to manage the assignment of workstations to users. Citrix recommends that you use a non-production environment for testing this beta. Set up user accounts with permissions to connect to workstations in the same domain in which you plan to install Citrix Desktop Server All Windows Servers and workstations used in the XenDesktop Tech Preview Kit must be members of this Domain. o o o • • Create an Organizational Unit (OU) at the root level. This OU is used to store all farm configuration and workstation group information. You must create a XenServer resource pool and add the server running the XenServer Host to the resource pool, even if your deployment contains only a single XenServer Host. To be part of a Resource Pool, XenServer Hosts need to have static IP addresses. For this beta release, you must install all the server-side components of XenDesktop Server on a single server. You can install the Virtual Desktop Agent on up to 120 workstations. o XenDesktop Server, the management consoles, Citrix licensing, the Web Interface, the Web Client, and the farm data store, are installed on a single server. • Getting Started Guide 3 o o Windows XP Professional 32-bit, with Service Pack 2 workstations host the workstation-side components. Both XenDesktop Server and the workstations should be installed on VMs in your XenServer virtualization infrastructure but can be installed on separate physical machines based on your available hardware. Requirements for Servers Servers Running Citrix XenServer must meet the following requirements: XenServer requires at least two separate physical computers: one to be the XenServer Host, and the other to run the XenCenter application. The XenServer Host machine is dedicated entirely to the task of hosting virtual machines (VMs) and is not used for other applications. The computer that runs XenCenter can be any general-purpose Windows computer that satisfies the hardware requirements, and can be used to run other applications simultaneously. XenServer Host system requirements: • One or more 64-bit x86 CPU(s), 1.5 GHz minimum, 2 GHz or faster multi-core CPU recommended. To support VMs running Windows, an Intel VT or AMD-V x86-based system with one or more (up to 32) CPUs is required. o To run Windows VMs, hardware support for virtualization must be enabled on the XenServer Host. This is an option in the BIOS. It is possible your BIOS might have virtualization support disabled. Consult your BIOS documentation for more details • • 1 GB minimum RAM, 2 GB or more recommended Locally attached storage (PATA, SATA, SCSI) with 16 GB of disk space minimum, 60 GB of disk space recommended. o o Product installation creates two 4GB partitions for the XenServer Host Control Domain; remaining space is available for VMs Ensure you have enough storage to accommodate Virtual machine images for the server and workstation components of this kit. • 100 Mbit/s or faster network interface card (NIC). A gigabit NIC is recommended for faster P2V and export/import data transfers and for live relocation of VMs. XenCenter requirements: The XenCenter application for managing the XenServer Host can be installed and run on any Windows 2000/XP/Vista workstation or laptop. The following are the system requirements for XenCenter: • • • • • • Windows 2000, Windows XP, Windows Server 2003, or Windows Vista .NET framework version 2.0 or above 750 MHz minimum CPU, 1 GHz or faster recommended 1 GB RAM minimum, 2 GB or more recommended 100 MB minimum disk space 100Mb or faster NIC Servers Running Citrix XenDesktop Server (Beta) must meet the following requirements: • • • • Microsoft Windows Server 2003 Enterprise Edition, with Service Pack 2 installed Terminal Services running in application mode Microsoft .NET Framework, Version 3.0 Java Runtime Environment (JRE) Version 1.5.0_09 4 Citrix Desktop Server, Version 2.0 • • • • Microsoft Internet Information Services (IIS) Version 6.0 and ASP.NET Microsoft Visual J# 2.0 Redistributable Package Internet Explorer 5.0 or later, if you are running licensing on the server Disk space requirements: o o o o 400 MB for Citrix Desktop Server 50 MB for the Presentation Server Console 25 MB for the Access Management Console 30 MB for the licensing components Note: If .Net Framework, Version 3.0, Microsoft Visual J# 2.0, and Java Runtime Environment are not already installed in your server, the XenDesktop Server Installation will install these pre-requisites prior to installing XenDesktop. The XenDesktop Server CD also provides .NET Framework 3.0 in the Support\DotNet30 folder, so you can install it separately if you prefer. Workstation Requirements For the Tech Preview kit, workstations must be running Windows XP Professional 32-bit, with Service Pack 2 installed. Note: Support components needed by workstations, such as .NET Framework 3.0 and Visual C++ 2005 Runtime, are automatically installed as part of the overall workstation package if they are not already on the workstation. The Citrix Desktop Server CD also provides .NET Framework 3.0 in the Support\DotNet30 folder, so you can install it separately if you prefer. Client Requirements This beta release includes a new version of the Clients for Windows. You cannot upgrade to this version of the client from previous versions installed on client devices. You must uninstall previous versions of the client before installing the version included with this beta release. Client devices must meet the following requirements: • • • • • • • • • Standard PC architecture, 80386 processor or greater as required for the operating system Windows XP Professional 32-bit , with Service Pack 2 installed Available memory as recommended for the operating system by Microsoft Internet Explorer Version 5.0 or later; Netscape Navigator or Communicator Version 4.78, 6.2, or later; Mozilla Firefox 1.0 or later Microsoft mouse or 100% compatible mouse VGA or SVGA video adapter with color monitor High-density 3.5-inch disk drive (optional) and available hard drive space Windows-compatible sound card for sound support (optional) For network connections to the server farm, a network interface card (NIC) and the appropriate network transport software are required Supported connection methods and network transports are: Getting Started Guide 5 Protocol Program Neighborhood Agent X X Web Client Program Neighborhood X X X X X X TCP/IP+HTTP SSL/TLS+HTTPS TCP/IP Installing Citrix XenServer This section details the installation of XenServer for use with the XenDesktop Tech Preview Kit. Steps include • • • • • Installing XenServer and XenCenter Licensing XenServer Creating a resource pool Creating XenServer VM images Installing the necessary paravirtualized drivers on VMs Installing XenServer consists of installing two components on two separate machines – XenServer Host and XenCenter. XenCenter provides the management tools to administer your XenServer Host. To install the XenServer Host: Note: Do not install any other operating system in a dual-boot configuration with the XenServer Host; this is an unsupported configuration. Note: For integration with XenDesktop Server you must create a XenServer resource pool and add the server running the XenServer Host to the resource pool, even if your deployment contains only a single XenServer Host. To be part of a Resource Pool, XenServer Hosts need to have static IP addresses. 1. 2. Boot the computer from a CD image of the XenServer ISO included in this kit (XenServer-4.0.1-install-cd.iso) or PXE-boot from your TFTP server if applicable. After the initial boot messages, the installer does some hardware detection and initialization then presents a screen asking you to select which keyboard keymap you want to use for the installation. In this and the screens that follow, use TAB or ALT+TAB to move between elements, SPACE to select, and F12 to move to the next screen. Select the desired keymap and choose OK to proceed. On the Welcome to XenServer page select Install XenServer Host and choose OK to proceed. The next screen displays a message telling you that the setup program will install XenServer on the computer, and warns that it will overwrite data on any hard drives that you select to use for the installation. Choose OK to proceed. The XenServer End User License Agreement (EULA) is displayed. Use the up and down arrow keys to scroll through and read the agreement. Choose Accept EULA to proceed. At this point, if the computer on which you are installing the XenServer Host does not have a CPU which supports hardware virtualization, or if the support is disabled in the BIOS, a message appears to warn you that you will not be able to run Windows VMs. Choose OK to proceed. Note that some systems have issues in their BIOS software which can result in the setting being incorrect. If you get a spurious warning about a lack of hardware virtualization (or do not see a warning when you expected one), then perform a hard power cycle of the host and restart the installation. You should also check the hardware manufacturer’s support site for BIOS upgrades. If the installer detects a previously-installed version of XenServer Host, you are offered the choice to perform a clean installation, or to re-install over the existing version, which preserves any of the VMs present. Select an installation type and choose OK to proceed. 3. 4. 5. 6. 7. 6 Citrix Desktop Server, Version 2.0 8. If you have multiple local hard disks, you are asked to choose the Primary Disk for the installation. Select the desired disk and choose OK to proceed. After selecting the primary one, you are also prompted to choose if you want any of the other drives to be formatted for use by XenServer for VM storage. Select and choose OK to proceed. If the computer has a single hard disk, these two screens do not appear. The next screen asks you to specify the source of the installation packages. If you are installing from CD, you will most likely want to select Local media. If you are installing via PXE you will most likely want to select HTTP or FTP or NFS, as appropriate. If you select HTTP or FTP or NFS, you are next prompted to set up Networking. If the computer has multiple network interfaces, you are prompted to select one of them to be used as the management NIC for the XenServer Host software. Select and choose OK to proceed. Note: Only the management NIC will be configured with an IP address. If you wish to use other NICs in a computer with multiple NICs, see the section "Network interface configuration" in the "Networking" chapter of the XenServer Administrator’s Guide. If the computer has a single network interface, that interface is used as the management NIC and no prompt is displayed. You can select to configure the management interface using DHCP, or specify a different network configuration, which prompts you to configure the management interface’s properties manually. Following that, you are prompted to provide the URL or NFS server and path where the installation media are, as appropriate. Note: To be part of a Resource Pool, XenServer Hosts need to have static IP addresses. If you select Local media, this networking setup appears later in the installation process. If you are planning to install VMs that will run Linux operating systems, check the Use additional media checkbox. If you are planning to install only Windows VMs, you can leave this checkbox unchecked. Choose OK to proceed. 9. 10. The next screen asks you if you want to verify the integrity of the installation media. If you select Verify installation source, the MD5 checksum of the packages is calculated and checked against the known value. This may take some time. If you select Skip verification, this check is bypassed. Make your selection and choose OK to proceed. 11. You are next prompted to set a root password. (This will be the password that the XenCenter application will use to connect to the XenServer Host.) Type the desired password and type it again to verify it. 12. You are prompted to select the general geographical area for the Time Zone. Choose from the displayed list of geographical areas then choose OK to proceed. 13. You are prompted to select the specific locale for the Time Zone. (Note that this list is long, but if you type the first letter of the desired locale, the selection will jump to the first entry that begins with this letter.) Choose from the displayed list of locales then choose OK to proceed. 14. You are prompted to choose a method of setting the System Time. You can select Using NTP or Manual time entry. Make your selection and choose OK to proceed. 15. If you selected Using NTP in the preceding step, you are prompted to identify the time server or servers you want to use. You can check NTP is configured by my DHCP server and the time server will be set by DHCP. Otherwise, enter at least one NTP server name or IP address in the fields below. Choose OK to proceed. Otherwise, the installation script moves to the next step; you will be prompted for the manually-entered time later, near the end of the installation. Note: Currently XenServer assumes that the time setting for the server’s BIOS is the current time in UTC, and that the time for the VMs reflects the local time based on the time zone offset specified. 16. If you selected Local media in the installation source step above, you are next prompted to set up Networking. If the computer has multiple network interfaces, you are prompted to select one of them to be used as the management NIC for the XenServer Host software. Select and choose OK to proceed. If the computer has a single network interface, that interface is used as the management NIC and no prompt is displayed. If you selected HTTP or FTP or NFS in the installation source step above, this first Networking step has already been performed. 17. You are next prompted to specify the hostname and the configuration for the name service. In the Hostname Configuration section, if you select Automatically set via DHCP, the DHCP server will provide the hostname Getting Started Guide 7 along with the IP address. If you select Manually specify, enter the desired hostname for the server in the field below. In the DNS Configuration section, if you select Manually specify, enter the IP addresses of your primary (required), secondary (optional), and tertiary (optional) Nameservers in the fields below. Otherwise, select Automatically set up via DHCP to get name service configuration via DHCP. Select OK to proceed. 18. A message is displayed that the installation is ready to proceed and that this will format the primary disk and any other disks selected for VM storage, destroying any data that is currently on them. Select Install XenServer Host to proceed. A progress bar is displayed as the installation commences. If you chose to set the system date and time manually, a dialog box appears when the progress bar has reached about 90%. Enter the correct numbers in the fields and select OK to proceed. 19. If you selected to install support for Linux VMs, you will be prompted to put in the Linux Support disk. Eject the main disk, put in the Linux Pack disk, and close the CD drawer. Select OK. A screen appears, identifying that this disk contains the Linux Pack. Select OK to proceed with installing it. Another progress bar is displayed, and when it reaches 100%, a completion message is displayed. If you selected not to install support for Linux VMs, a completion message is displayed. 20. Select Reboot. Upon reaching the login prompt, the system should now be ready to manage via XenCenter. To connect to it, you will need the IP address or hostname of the XenServer Host. This is displayed at the login prompt. To install XenCenter: XenCenter is a Windows client application. XenCenter must be installed on a remote machine that can connect to the XenServer Host through the network; it cannot run on the same machine as the XenServer Host. It can be installed and run on Windows 2000/2003/XP/Vista computers. The .NET framework version 2.0 or above must be installed as well. Before installing XenCenter, be sure to uninstall the previous version if one exists. 1. 2. Run XenCenterSetup.exe. Follow the instructions displayed in the installer window. When prompted for installation directory, either click Browse to change the default installation location, or click Next to accept the default path C:\ProgramFiles\XenSource\XenCenter.
