3.5. Installation von Windows Server 2008 als voll virtualisierter Gast

Dieser Abschnitt beschreibt die Installation eines voll virtualisierten Windows Server 2008 Gasts.
Prozedur 3.4. Installation von Windows Server 2008 mit virt-manager
  1. Open virt-manager

    Start virt-manager. Launch the Virtual Machine Manager application from the Applications menu and System Tools submenu. Alternatively, run the virt-manager command as root.
  2. Select the hypervisor

    Select the hypervisor. If installed, select Xen or KVM. For this example, select KVM. Note that presently KVM is named qemu.
    Nachdem die Option gewählt wurde, erscheint die Schaltfläche Neu. Klicken Sie auf Neu.
  3. Start the new virtual machine wizard

    Pressing the New button starts the virtual machine creation wizard.
    Press Forward to continue.
  4. Name the virtual machine

    Provide a name for your virtualized guest. Punctuation and whitespace characters are not permitted.
    Press Forward to continue.
  5. Choose a virtualization method

    Choose the virtualization method for the virtualized guest. Note you can only select an installed virtualization method. If you selected KVM or Xen earlier (step 2) you must use the hypervisor you selected. This example uses the KVM hypervisor.
    Press Forward to continue.
  6. Select the installation method

    Für alle Windows-Versionen müssen Sie ein Lokales Installationsmedium verwenden, also entweder ein ISO-Abbild oder ein physisches, optisches Medium.
    Falls Sie einen PXE-Server für Windows-Netzwerkinstallationen konfiguriert haben, kann auch PXE verwendet werden. PXE-Windows-Installation wird in diesem Handbuch jedoch nicht behandelt.
    Set OS Type to Windows and OS Variant to Microsoft Windows 2008 as shown in the screenshot.
    Press Forward to continue.
  7. Locate installation media

    Wählen Sie "Speicherort des ISO-Abbilds" oder "CD-ROM oder DVD-Laufwerk". In diesem Beispiel wird ein ISO-Dateiabbild der Windows Server 2008 Installations-CD verwendet.
    1. Press the Browse button.
    2. Search to the location of the ISO file and select it.
      Press Open to confirm your selection.
    3. The file is selected and ready to install from.
      Press Forward to continue.

    Image files and SELinux

    For ISO image files and guest storage images, the recommended directory to use is the /var/lib/libvirt/images/ directory. Any other location may require additional configuration for SELinux, refer to Abschnitt 7.1, „SELinux und Virtualisierung“ for details.
  8. Storage setup

    Assign a physical storage device (Block device) or a file-based image (File). File-based images must be stored in the /var/lib/libvirt/images/ directory. Assign sufficient storage for your virtualized guest. Assign sufficient space for your virtualized guest and any application it requires.
    Press Forward to continue.
  9. Network setup

    Select either Virtual network or Shared physical device.
    The virtual network option uses Network Address Translation (NAT) to share the default network device with the virtualized guest. Use the virtual network option for wireless networks.
    The shared physical device option uses a network bond to give the virtualized guest full access to a network device.
    Press Forward to continue.
  10. Memory and CPU allocation

    The Allocate memory and CPU window displays. Choose appropriate values for the virtualized CPUs and RAM allocation. These values affect the host's and guest's performance.
    Virtualized guests require sufficient physical memory (RAM) to run efficiently and effectively. Choose a memory value which suits your guest operating system and application requirements. Windows Server 2008. Remember, guests use physical RAM. Running too many guests or leaving insufficient memory for the host system results in significant usage of virtual memory and swapping. Virtual memory is significantly slower causing degraded system performance and responsiveness. Ensure to allocate sufficient memory for all guests and the host to operate effectively.
    Assign sufficient virtual CPUs for the virtualized guest. If the guest runs a multithreaded application assign the number of virtualized CPUs it requires to run most efficiently. Do not assign more virtual CPUs than there are physical processors (or hyper-threads) available on the host system. It is possible to over allocate virtual processors, however, over allocating has a significant, negative affect on guest and host performance due to processor context switching overheads.
    Press Forward to continue.
  11. Verify and start guest installation

    Verify the configuration.
    Press Finish to start the guest installation procedure.
  12. Installation von Windows

    Complete the Windows Server 2008 installation sequence. The installation sequence is not covered by this guide, refer to Microsoft's documentation for information on installing Windows.
