Definitive guide for the acceleration 3D on VirtualBox

As you know I have already written two posts on 'subject, Acceleration 3D on VirtualBox and Habemus 3D, and at this point I felt the need to organize this kind of notes to build a comprehensive and relatively easy to use. If you read the post above and have some experience to know that VirtualBox architecture dl system virtualization provides a host machine, where is the operating system "real", and a machine with the guest virtual system. The trick is to try to put the two communication systems and ensure that "guest" exploiting the host of 3D acceleration. To do this we first need vmgl, a software developed by the genius of a Canadian developer of a script to create a host interface that will allow the two machines to communicate, to a small number of configurations on both systems and a po 'di patience.

Prerequisites

In my case the host machine is equipped with Ubuntu Hardy Heron and the guest with OpenSUSE 11, and now the call respectively hardy and suse.
On hardy installed everything necessary for the compilation (make, build-essential ...) + the following packages: freeglut3-dev, libxmu-dev, libbz2-dev, zlib1g-dev, libssl-dev, libjpeg62-dev, libjasper-dev.
Follow my guide on the installation and configuration of OpenSuse 11 on VirtualBox procastinando but l 'installarzione the guest additions after the vmgl (the next step). Also you need to install suse on the need to compile (make, gcc, gcc + +, kernel source ...) + the version of suse packages above: freeglut-devel, xorg-x11-devel-libxmu, libbz2-devel, libopenssl - devel, libjpeg-devel, libjasper-devel.
Obviously there will be many dependencies to be met er which to prepare nstallare a lot 'of stuff.

Installing vmgl

Hardy
Making vmgl download from the link above, unpack the tar.gz archive in your home, get in vmgl.hg type and make, make install-host.
Suse
In / home / $ user / vmgl.hg type make, make install-guest.

Configuration

Hardy
Open the file / etc / gdm / gdm.conf DisallowTCP and change in DisallowTCP = true = false; saved and run as root stub-daemon. Now stored in / etc / hosts the ip address of suse (suppose 192.168.0.3) followed by the hostname (eg linux-zlug), this completes the line: 192.168.0.3 linux-zlug.

Suse
Create an interface with the host script leo, quietly follow the instructions, you should only change your user name, and run VirtualBox with the network interface tap1. Assigned to suse ip address 192.168.0.3 in / etc / hosts Enter the IP address of hardy (192.168.0.2) and hostname (eg maddomlinux); full line: 192.168.0.2 maddomlinux. Open the port 6000 for 'X forwarding by running YaST-> editor for file / etc/sysconfig-> Desktop-> Display Manager and changing the value of DISPLAYMANAGER_XSERVER_TCP_PORT_6000_OPEN from no to yes.
Finally the file / etc / environment included the following lines:
DISPLAY = hostname: 0
GLSTUB = hostname: 7000
Restart, et voilà:

* hostname = the name of the host machine (hardy). In my case maddomlinux.

Update 9/07/2008

Few lines above, I documented how to create a telnet X11Forwarding through implementing the DISPLAY variable in / etc / environment. There is also another way, that is to use ssh-X from the host machine (hardy). In my type of setup works best so that I can show to john (my commentator english) and all of you a screenshot (the first of two) of gnuchess 3D (only the keyboard, not the pawns I may ...) . Operation is simple:

ssh-X username @ host (in my case mad73 @ linux-zlug).
