Introduction to VirtualBox

VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.[1]

Dependencies

VirtualBox only supports x86 and x86_64.

Required

• Dev86
• IASL
• LibXSLT
• Xalan-C++
• Qt3
• libIDL
• SDL
• ALSA

Optional

• GCC-3.3

Creating the vboxusers Group

groupadd -g 29 vboxusers

Users that are going to use VirtualBox should be added to this group.

Non-Multilib

Compile VirtualBox:

sed -i "s@/usr/X11R6@${XORG_PREFIX}@g" $(grep -lr /usr/X11R6 *) &&
./configure --with-xerces="-lpthread -lxerces-c" \
    --with-qt-dir=$QTDIR &&
source env.sh &&
kmk

Build the kernel module:

cd out/linux.*/release/bin/src &&
make

Install the kernel module:

make install

Install VirtualBox:

cd .. &&
install -m755 -d -v /opt/VirtualBox &&
cp -av * /opt/VirtualBox

Multilib

ToDo

Configuring

The kernel module needs to be loaded for VirtualBox to function. Make sure it gets loaded on boot:

echo "vboxdrv" >> /etc/sysconfig/modules

Also lets create a udev rule so that /dev/vboxdev can be accessed by the users in the vboxusers group.

cat > /etc/udev/rules.d/90-vboxdev.rules << "EOF"
KERNEL=="vboxdev", NAME="%k", MODE="0660", GROUP="vboxusers"
EOF

Create a helper script that will start VBoxSVC and then execute the specified client:

cat > /opt/VirtualBox/VBox.sh << "EOF"
#!/bin/sh

INSTALL_PATH="/opt/VirtualBox"
export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}${LD_LIBRARY_PATH+:}${INSTALL_PATH}"

if [ ! -c /dev/vboxdrv ]; then
  echo "/dev/vboxdrv does not exist. Load the kernel module then try again."
  exit 1
fi
if [ ! -r /dev/vboxdrv -o ! -w /dev/vboxdrv ]; then
  echo "User $(whoami) can not read and/or write to /dev/vboxdrv."
  exit 1
fi

SERVER_GET_PID="eval SERVER_PID=\$(ps -U $(whoami) | grep VBoxSVC | awk '{ print \$1 }')"

$SERVER_GET_PID
if [ "$1" = "shutdown" -a -n "$SERVER_PID" ]; then
  kill -TERM $SERVER_PID
  exit 0
fi

if [ ! -x "$INSTALL_PATH/VBoxSVC" ]; then
  echo "$INSTALL_PATH/VBoxSVC does not exist! Can not continue."
  exit 1
fi

APP=$(which $0)
APP=${APP##/*/}

if [ ! -x "$INSTALL_PATH/$APP" ]; then
  echo "$INSTALL_PATH/$APP does not exist!"
  exit 1
fi
case "$APP" in
  VirtualBox|VBoxManage|VBoxSDL|VBoxVRDP)
    EXEC_APP="$INSTALL_PATH/$APP"
  ;;
  *)
    echo "Unknown application - $APP"
  ;;
esac

if [ -z "$SERVER_PID" ]; then
   rm -rf /tmp/.vbox-$(whoami)-ipc
   "$INSTALL_PATH/VBoxSVC" --daemonize
fi

$SERVER_GET_PID
if [ -z "$SERVER_PID" ]; then
  echo "VBoxSVC failed to start. Can not continue"
  exit 1
fi

exec "$EXEC_APP" "$@"
EOF

A script similar to the one above is shipped with the binary version.

Link the binaries we want to run to the script:

for file in VirtualBox VBoxManage VBoxSDL VBoxVRDP; do
  [ -f "/opt/VirtualBox/$file" ] && ln -sfv "../../opt/VirtualBox/VBox.sh" "/usr/bin/$file"
done

Create a desktop file:

cat > /usr/share/applications/VirtualBox.desktop << "EOF"
[Desktop Entry]
Encoding=UTF-8
Version=1.3.8
Name=InnoTek VirtualBox
GenericName=Virtual Machine
Type=Application
Comment=Run several virtual systems on a single host computer
Exec=VirtualBox
TryExec=VirtualBox
Path=
Icon=VBox.png
Categories=Application;Emulator;System
EOF

Finally grab the pixmap http://cblfs.cross-lfs.org/images/6/61/VBox.png and put it in /usr/share/pixmaps.
