  1. Create an LXC container.

     sudo lxc-create -t ubuntu -n gravity

  2. Edit the container configuration file (/var/lib/lxc/gravity/config) and add these lines:

     lxc.cgroup.devices.allow = c 1:1 rwm # dev/mem
 lxc.cgroup.devices.allow = c 13:63 rwm # dev/input/mice
 lxc.cgroup.devices.allow = c 195:* rwm # dev/nvidia*

  3. Edit the container fstab file (/var/lib/lxc/gravity/fstab) and add these lines:

     /dev/dri dev/dri none bind,optional,create=dir
 /dev/snd dev/snd none bind,optional,create=dir
 /tmp/.X11-unix tmp/.X11-unix none bind,optional,create=dir
 /dev/video0 dev/video0 none bind,optional,create=file
 /dev/nvidiactl dev/nvidiactl none bind,optional,create=file
 /dev/nvidia0 dev/nvidia0 none bind,optional,create=file

  4. Copy source code into the container:

     sudo cp -r /path/to/source/code/of/gravity /var/lib/lxc/gravity/rootfs/home/ubuntu/
 sudo cp /path/to/box2d-2.4.1.tar.xz /var/lib/lxc/gravity/rootfs/home/ubuntu/

  5. Start the container.

     sudo lxc-start -n gravity -d

  6. Attach to the container (login with the user ubuntu and password ubuntu):

     sudo lxc-console -n gravity

  7. Set apt proxy if necessary. Create a /etc/apt/apt.conf.d/90proxy and put something like this in it:

     Acquire::http { Proxy "http://10.0.3.1:3142"; };

  8. Install the needed tools and libraries:

     sudo apt-get install python build-essential pulseaudio alsa libsdl2-dev libsdl2-mixer-dev libsdl2-ttf-dev libglew-dev nvidia-current

  9. Load PulseAudio TCP module by running the following command on the host:

     pactl load-module module-native-protocol-tcp

  10. Set the PulseAudio server in the guest:

    export PULSE_SERVER=10.0.3.1:4713

  11. Set the X DISPLAY environment variable:

    export DISPLAY=:0.0

  12. Correct the ownership of the source code directory:

    sudo chown ubuntu ~/gravity/ -R

  13. Build and install Box2D:

    cd
tar -xf box2d-2.4.1.tar.xz
cd box2d-2.4.1/
./build.sh
sudo cp build/bin/libbox2d.a /usr/local/lib/
cd ../..
sudo cp -r box2d/ /usr/local/include/

  14. Build the game:

    cd ~/gravity/
./waf configure --release
./waf build

  15. Run the game:

    ./build/gravity
