  <title>Installation details</title>

  <para>As installation of VirtualBox varies depending on your host operating
  system, we provide installation instructions in four separate chapters for
  Windows, Mac OS X, Linux and Solaris, respectively.</para>

  <sect1>
    <title>Installing on Windows hosts</title>

    <sect2>
      <title>Prerequisites</title>

      <para>For the various versions of Windows that we support as host
      operating systems, please refer to <xref
      linkend="hostossupport" />.</para>

      <para>In addition, Windows Installer 1.1 or higher must be present on
      your system. This should be the case if you have all recent Windows
      updates installed.</para>
    </sect2>

    <sect2>
      <title>Performing the installation</title>

      <para>The VirtualBox installation can be started <itemizedlist>
          <listitem>
            <para>either by double-clicking on its executable file (contains
            both 32- and 64-bit architectures)</para>
          </listitem>

          <listitem>
            <para>or by entering <screen>VirtualBox.exe -extract</screen></para>

            <para>on the command line. This will extract both installers into
            a temporary directory in which you'll then find the usual .MSI
            files. Then you can do a <screen>msiexec /i VirtualBox-&lt;version&gt;-MultiArch_&lt;x86|amd64&gt;.msi</screen>
            to perform the installation.</para>
          </listitem>
        </itemizedlist></para>

      <para>In either case, this will display the installation welcome dialog
      and allow you to choose where to install VirtualBox to and which
      components to install. In addition to the VirtualBox application, the
      following components are available:<glosslist>
          <glossentry>
            <glossterm>USB support</glossterm>

            <glossdef>
              <para>This package contains special drivers for your Windows
              host that VirtualBox requires to fully support USB devices
              inside your virtual machines.</para>

          </glossentry>

          <glossentry>
            <glossterm>Networking</glossterm>

            <glossdef>
              <para>This package contains extra networking drivers for your
              Windows host that VirtualBox needs to support Host Interface
              Networking (to make your VM's virtual network cards accessible
              from other machines on your physical network).</para>
            </glossdef>
          </glossentry>

          <glossentry>
            <glossterm>Python Support</glossterm>

            <glossdef>
              <para>This package contains Python scripting support for the
              VirtualBox API (see <xref linkend="VirtualBoxAPI" />). To get this
              feature installed an already working Python installation on the
              system is required.</para>
            </glossdef>
          </glossentry>
        </glosslist></para>

      <para>Depending on your Windows configuration, you may see warnings
      about "unsigned drivers" or similar. Please select "Continue" on these
      warnings as otherwise VirtualBox might not function correctly after
      installation.</para>

      <para>The installer will create a "VirtualBox" group in the programs
      startup folder which allows you to launch the application and access its
      documentation.</para>

      <para>With standard settings, VirtualBox will be installed for all users
      on the local system. In case this is not wanted, you have to invoke the
      installer by first extracting it by using <screen>VirtualBox.exe -extract</screen>
      and then do as follows: <screen>VirtualBox.exe -msiparams ALLUSERS=2</screen>
      or <screen>msiexec /i VirtualBox-&lt;version&gt;-MultiArch_&lt;x86|amd64&gt;.msi ALLUSERS=2</screen>
      on the extracted .MSI files. This will install VirtualBox only for the
      current user.</para>

      <para>To not install certain features of VirtualBox there is an <computeroutput>ADDLOCAL</computeroutput>
      parameter that can be specified additionally to explicitly name the features
      to be installed. The following features are available:

              <para>Main binaries of VirtualBox.
                <note>This feature never can be absent,
                since it contains the minimum set of files to have working VirtualBox installation!</note>

      <title>The VirtualBox kernel module</title>

      <para>VirtualBox uses a special kernel module to perform physical memory
      allocation and to gain control of the processor for guest system
      execution. Without this kernel module, you will still be able to work
      with virtual machines in the configuration interface, but you will not
      be able to start any virtual machines.</para>

      <para>The VirtualBox kernel module is automatically installed on your
      system when you install VirtualBox. To maintain it with future kernel
      updates, for recent Linux distributions -- for example Fedora Core 5 and
      later, Ubuntu 7.10 (Gutsy) and later and Mandriva 2007.1 and later --,
      generally we recommend installing Dynamic Kernel Module Support
      (DKMS)<footnote>
          <para>See <ulink
          url="http://en.wikipedia.org/wiki/Dynamic_Kernel_Module_Support">http://en.wikipedia.org/wiki/Dynamic_Kernel_Module_Support</ulink>
          for an introduction.</para>
        </footnote>. This framework helps to build kernel modules and to deal
      with kernel upgrades.</para>

      <para>If DKMS is not already installed, execute one of the following:
      <itemizedlist>
          <listitem>
            <para>On an Ubuntu system:</para>

            <screen>sudo apt-get install dkms</screen>
          </listitem>

          <listitem>
            <para>On a Fedora system:<screen>yum install dkms</screen></para>
          </listitem>

          <listitem>
            <para>On a Mandriva system:<screen>urpmi dkms</screen></para>
          </listitem>
        </itemizedlist></para>

      <para>If DKMS is available and installed, the VirtualBox kernel module
      should always work automatically, and it will be automatically rebuilt
      if your host kernel is updated.</para>

      <para>Otherwise, there are only two situations in which you will need to
      worry about the kernel module:<orderedlist>

            your Linux system is not prepared for building external kernel
            modules.</para>

            <para>Most Linux distributions can be set up simply by installing
            the right packages - normally, these will be the GNU compiler
            (GCC), GNU Make (make) and packages containing header files for
            your kernel - and making sure that all system updates are
            installed and that the system is running the most up-to-date
            kernel included in the distribution. <emphasis>The version numbers
            of the header file packages must be the same as that of the kernel

      <!--TODO Write a couple of notes about hardened kernels. If PaX is installed, VBox presently doesn't start. I tried with a
gentoo hardened kernel that had PaX enabled, and VBoxHeadless failed with really funny VERR_NO_MEMORY messages. Discussing
it with Knut revealed that PaX might be the problem, and running paxctl to disable these protections actually
helped. For reference:
First run paxctl -C VBoxVDRP to have the executable modified to support PaX flags in the first place.
Then paxctl -pemrxs VBoxHeadless to disable all protections. TODO: Figure out which ones are really needed.-->

      <title>Performing the installation</title>

      <para>VirtualBox is available in a number of package formats native to
      various common Linux distributions (see <xref linkend="hostossupport" />
      for details). In addition, there is an alternative generic installer
      (.run) which should work on most Linux distributions.</para>

      <sect3>
        <title>Installing VirtualBox from a Debian/Ubuntu package</title>

        <para>First, download the appropriate package for your distribution.
        The following examples assume that you are installing to a 32-bit Ubuntu
        Karmic system. Use <computeroutput>dpkg</computeroutput> to install the
        Debian package:</para>

        <screen>sudo dpkg -i VirtualBox-3.2_$VBOX_VERSION_STRING_Ubuntu_karmic_i386.deb</screen>

        <para>You will be asked to accept the VirtualBox Personal Use and
        Evaluation License. Unless you answer "yes" here, the installation
        will be aborted.</para>

        <para>The group <computeroutput>vboxusers</computeroutput> will be
        created during installation. Note that a user who is going to run
        VirtualBox must be member of that group. A user can be made member of
        the group <computeroutput>vboxusers</computeroutput> through the GUI
        user/group management or at the command line with</para>

        <screen>sudo usermod -a -G vboxusers username</screen>

        <para>Also note that adding an active user to that group will require
        that user to log out and back in again. This should be done manually
        after successful installation of the package.</para>

        <para>The installer will also search for a VirtualBox kernel module
        suitable for your kernel. The package includes pre-compiled modules
        for the most common kernel configurations. If no suitable kernel
        module is found, the installation script tries to build a module
        itself. If the build process is not successful you will be shown a
        warning and the package will be left unconfigured. Please have a look
        at <computeroutput>/var/log/vbox-install.log</computeroutput> to find
        out why the compilation failed. You may have to install the
        appropriate Linux kernel headers (see <xref
        linkend="externalkernelmodules" />). After correcting any problems, do
        <screen>sudo /etc/init.d/vboxdrv setup</screen>This will start a
        second attempt to build the module.</para>

        <para>If a suitable kernel module was found in the package or the
        module was successfully built, the installation script will attempt to
        load that module. If this fails, please see <xref
        linkend="linuxkernelmodulefailstoload" /> for further
        information.</para>

        <para>Once VirtualBox has been successfully installed and configured,
        you can start it by selecting "VirtualBox" in your start menu or from
        the command line (see <xref linkend="startingvboxonlinux" />).</para>
      </sect3>

      <sect3>
        <title>Using the alternative installer (VirtualBox.run)</title>

        <para>The alternative installer performs the following steps:</para>

        <itemizedlist>
          <listitem>
            <para>It unpacks the application files to a target directory of

        <para>The installer must be executed as root with either
        <computeroutput>install</computeroutput> or
        <computeroutput>uninstall</computeroutput> as the first parameter. If
        you do not want the installer to ask you whether you wish to accept
        the license agreement (for example, for performing unattended
        installations), you can add the parameter
        <computeroutput>license_accepted_unconditionally</computeroutput>.
        Finally, if you want to use a directory other than the default
        installation directory, add the desired path as an extra
        parameter.</para>

        <screen>sudo ./VirtualBox.run install /opt/VirtualBox</screen>

        <para>Or if you do not have the "sudo" command available, run the
        following as root instead:<screen>./VirtualBox.run install /opt/VirtualBox</screen></para>

        <para>After that you need to put every user which should be able to
        use VirtualBox in the group
        <computeroutput>vboxusers</computeroutput>, either through the GUI
        user management tools or by running the following command as
        root:</para>

        <screen>sudo usermod -a -G vboxusers username</screen>

        <para><note>
            <para>The <computeroutput>usermod</computeroutput> command of some
            older Linux distributions does not support the
            <computeroutput>-a</computeroutput> option (which adds the user to
            the given group without affecting membership of other groups). In
            this case, find out the current group memberships with the
            <computeroutput>groups</computeroutput> command and add all these
            groups in a comma-separated list to the command line after the
            <computeroutput>-G</computeroutput> option, e.g. like this:
            <computeroutput>usermod -G group1,group2,vboxusers
            username</computeroutput>.</para>
          </note>If any users on your system should be able to access host USB
        devices from within VirtualBox guests, you should also add them to the

        <title>Performing a manual installation</title>

        <para>If, for any reason, you cannot use the shell script installer
        described previously, you can also perform a manual installation.
        Invoke the installer like this:</para>

        <screen>./VirtualBox.run --keep --noexec</screen>

        <para>This will unpack all the files needed for installation in the
        directory <computeroutput>install</computeroutput> under the current
        directory. The VirtualBox application files are contained in
        <computeroutput>VirtualBox.tar.bz2</computeroutput> which you can
        unpack to any directory on your system. For example:</para>

        <screen>sudo mkdir /opt/VirtualBox
sudo tar jxf ./install/VirtualBox.tar.bz2 -C /opt/VirtualBox</screen>

        <para>or as root:<screen>mkdir /opt/VirtualBox
tar jxf ./install/VirtualBox.tar.bz2 -C /opt/VirtualBox</screen></para>

        <para>The sources for VirtualBox's kernel module are provided in the
        <computeroutput>src</computeroutput> directory. To build the module,
        change to the directory and issue</para>

        <screen>make</screen>

        <para>If everything builds correctly, issue the following command to
        install the module to the appropriate module directory:</para>

        <screen>sudo make install</screen>

        <para>In case you do not have sudo, switch the user account to root
        and perform<screen>make install</screen></para>

        <para>The VirtualBox kernel module needs a device node to operate. The
        above make command will tell you how to create the device node,
        depending on your Linux system. The procedure is slightly different
        for a classical Linux setup with a
        <computeroutput>/dev</computeroutput> directory, a system with the now
        deprecated <computeroutput>devfs</computeroutput> and a modern Linux
        system with <computeroutput>udev</computeroutput>.</para>

        <para>On certain Linux distributions, you might experience
        difficulties building the module. You will have to analyze the error
        messages from the build system to diagnose the cause of the problems.
        In general, make sure that the correct Linux kernel sources are used
        for the build process.</para>

        <para>Note that the user who is going to run VirtualBox needs read and
        write permission on the VirtualBox kernel module device node
        <computeroutput>/dev/vboxdrv</computeroutput>. You can either define a
        <computeroutput>vboxusers</computeroutput> group by entering<screen>groupadd vboxusers
chgrp vboxusers /dev/vboxdrv
chmod 660 /dev/vboxdrv</screen>or, alternatively, simply give all users access
        (insecure, not recommended!)<screen>chmod 666 /dev/vboxdrv</screen>You
        should also add any users who will be allowed to use host USB devices
        in VirtualBox guests to the appropriate USB users group for your
        distribution. This group is often called
        <computeroutput>usb</computeroutput> or
        <computeroutput>usbusers</computeroutput>.</para>

        <para>Next, you will have to install the system initialization script
        for the kernel module:<screen>cp /opt/VirtualBox/vboxdrv.sh /etc/init.d/vboxdrv</screen>(assuming
        you installed VirtualBox to the
        <computeroutput>/opt/VirtualBox</computeroutput> directory) and
        activate the initialization script using the right method for your
        distribution. You should create VirtualBox's configuration
        file:<screen>mkdir /etc/vbox
echo INSTALL_DIR=/opt/VirtualBox &gt; /etc/vbox/vbox.cfg</screen>and, for
        convenience, create the following symbolic links:</para>

        <screen>ln -sf /opt/VirtualBox/VBox.sh /usr/bin/VirtualBox
ln -sf /opt/VirtualBox/VBox.sh /usr/bin/VBoxSVC
ln -sf /opt/VirtualBox/VBox.sh /usr/bin/VBoxManage

        <title>Updating and uninstalling VirtualBox</title>

        <para>Before updating or uninstalling VirtualBox, you must terminate
        any virtual machines which are currently running and exit the
        VirtualBox or VBoxSVC applications. To update VirtualBox, simply run
        the installer of the updated version. To uninstall VirtualBox, invoke
        the installer like this: <screen>sudo ./VirtualBox.run uninstall</screen>
        or as root<screen>./VirtualBox.run uninstall</screen>. Starting with
        version 2.2.2, you can uninstall the .run package by invoking <screen>/opt/VirtualBox/uninstall.sh</screen>To
        manually uninstall VirtualBox, simply undo the steps in the manual
        installation in reverse order.</para>

        <title>Automatic installation of Debian packages</title>

        <para>The Debian packages will request some user feedback when
        installed for the first time. The debconf system is used to perform
        this task. To prevent any user interaction during installation,
        default values can be defined. A file
        <computeroutput>vboxconf</computeroutput> can contain the following
        debconf settings: <screen>virtualbox virtualbox/module-compilation-allowed boolean true
virtualbox virtualbox/delete-old-modules boolean true</screen>The first line
        allows compilation of the vboxdrv kernel module if no module was found
        for the current kernel. The second line allows the package to delete
        any old vboxdrv kernel modules compiled by previous
        installations.</para>

        <para>These default settings can be applied with <screen>debconf-set-selections vboxconf</screen>
        prior to the installation of the VirtualBox Debian package.</para>

        <para>In addition there are some common configuration options that can be set prior to

      consists of a service daemon (<computeroutput>VBoxSVC</computeroutput>)
      and several application programs. The daemon is automatically started if
      necessary. All VirtualBox applications will communicate with the daemon
      through Unix local domain sockets. There can be multiple daemon

      communicate with the daemon running under the user account as the
      application. The local domain socket resides in a subdirectory of your

      versions of VirtualBox. <emphasis>The installation must be performed as
      root and from the global zone</emphasis> as the VirtualBox installer
      loads kernel drivers which cannot be done from non-global zones. To
      verify which zone you are currently in, execute the
      <computeroutput>zonename</computeroutput> command. Execute the following
      commands:</para>

      <screen>gunzip -cd VirtualBox-$VBOX_VERSION_STRING-SunOS.tar.gz | tar xvf -</screen>

      <para>Starting with VirtualBox 3.1 the VirtualBox kernel package is no
      longer a separate package and has been integrated into the main package.
      Install the VirtualBox package using:</para>

      <screen>pkgadd -d VirtualBox-$VBOX_VERSION_STRING-SunOS.pkg</screen>

      <note>
        <para>If you are using Solaris Zones, to install VirtualBox only into
        the current zone and not into any other zone, use

        linkend="solariszones" />.</para>
      </note>

      <para>The installer will then prompt you to enter the package you wish
      to install. Choose "1" or "all" and proceed. Next the installer will ask
      you if you want to allow the postinstall script to be executed. Choose
      "y" and proceed as it is essential to execute this script which installs
      the VirtualBox kernel module. Following this confirmation the installer
      will install VirtualBox and execute the postinstall setup script.</para>

      <para>Once the postinstall script has been executed your installation is
