    991. Create a [https://www.virtualbox.org VirtualBox] container, and install Ubuntu 10.04 LTS from http://releases.ubuntu.com/lucid/ubuntu-10.04.4-desktop-i386.iso. For easy use you can optionally install Guest Additions on the Ubuntu VM to copy-paste commands in the terminal from your host machine. This first step should have been done before getting to this page, but is mentioned to double check before proceeding.
    1010
    11 2. Before getting started make sure the machine is up to date.[[br]]
    12     `sudo apt-get update`[[br]]
    13     `sudo apt-get upgrade`
    14 
    15 3. Reconfigure dash. When the "Configuring dash" screen appears select NO.[[br]]
    16     `sudo dpkg-reconfigure dash`
    17 
    18 4. Install required packages to compile the kernel. This will be needed when the OpenVZ kernel is compiled.[[br]]
    19     `sudo apt-get install kernel-package libncurses5-dev fakeroot wget bzip2 module-assistant debhelper build-essential bridge-utils`
    20 
    21 5. Set the following variables that will be used.[[br]]
    22     `Variant="linux-image-generic"`[[br]]
    23     `VersionAppendix="-openvz"`[[br]]
    24     `MyConfigFile="kernel-2.6.32-i686.config.ovz"`[[br]]
    25 
    26 6. Set the build dependencies for OpenVZ[[br]]
    27     `Package="$(apt-cache showpkg $Variant | grep "^2\.6\.32" | grep "linux-image")"`[[br]]
    28     `Package=$(ReturnWord () { echo $3; }; ReturnWord $Package)`[[br]]
    29     `sudo apt-get build-dep --no-install-recommends $Package`[[br]]
    30 
    31 7. Prepare the linux headers before compiling, and create the configuration for the kernel.[[br]]
    32     `sudo m-a prepare`[[br]]
    33     `sudo kernel-packageconfig`
    34 
    35 9. Set up multi-core support. This step may not be necessary if your VM is only using one core, but it does not hurt to execute this line anyway.[[br]]
    36     `Cores=$(Nr () { echo $#; }; Nr $(grep "processor" /proc/cpuinfo | cut -f2 -d":"))`[[br]]
    37     `echo "CONCURRENCY_LEVEL := $(($Cores + 1))" | sudo tee -a /etc/kernel-pkg.conf`[[br]]
    38 
    39 10. Download the linux kernel source code.[[br]]
    40     `cd /usr/src`[[br]]
    41     `sudo wget http://archive.ubuntu.com/ubuntu/pool/main/l/linux/linux_2.6.32.orig.tar.gz`
    42 
    43 11. Get the OpenVZ patch for the linux kernel, and the OpenVZ kernel itself.[[br]]
    44     `sudo wget http://download.openvz.org/kernel/branches/2.6.32/current/patches/patch-feoktistov.1-combined.gz`[[br]]
    45     `sudo wget http://download.openvz.org/kernel/branches/2.6.32/current/configs/$MyConfigFile`
    46 
    47 12. Unpack the source code.[[br]]
    48     `sudo rm -fR linux-2.6.32`[[br]]
    49     `sudo tar -xpf linux_2.6.32.orig.tar.gz`[[br]]
    50     `sudo rm -fR "linux-2.6.32$VersionAppendix"`[[br]]
    51     `sudo mv linux-2.6.32 "linux-2.6.32$VersionAppendix"`[[br]]
    52     `sudo rm linux`[[br]]
    53     `sudo ln -s "linux-2.6.32$VersionAppendix" linux`
    54 
    55 13. Apply the OpenVZ patch to the kernel.[[br]]
    56     `cd /usr/src/linux`[[br]]
