+Using the virtual machine
+*************************
+
+Introduction
+============
+
+A virtual machine with a ready-to-use *Modoboa* setup is available
+`here <http://modoboa.org/resources/modoboa.vmdk.bz2>`_. It is composed
+of the following components:
+
+* Debian 6.0 (squeeze)
+* Modoboa and its prerequisites
+* MySQL
+* Postfix
+* Dovecot
+* saslauthd
+* nginx and gunicorn
+
+Actually, it is the result you obtain if you follow the official
+documentation.
+
+The disk image is using the `VMDK
+<http://en.wikipedia.org/wiki/VMDK>`_ format and is compressed using
+bzip2. To decompress it, just run the following command::
+
+  $ bunzip2 modoboa.vmdk.bz2
+
+If you can't use the vmdk format, you can use `qemu
+<http://qemu.org/>`_ to convert it to another one. For example::
+
+  $ qemu-img convert modoboa.vmdk -O qcow2 modoboa.qcow2
+
+Then, just use your prefered virtualization software (qemu, kvm,
+virtualbox, etc.) to start the machine. You'll need to configure at
+least one bridged network interface if you want to be able to play
+with *Modoboa*, ie. your machine must be visible from your network.
+
+The default network interface of the machine (``eth0``) is configured
+to use the DHCP protocol.
+
+Connect to the machine
+======================
+
+The following UNIX users are available if you want to connect to the system:
+
+===== ======== ====================
+Login Password Description
+===== ======== ====================
+root  demo     the root user
+demo  demo     an unpriviliged user
+===== ======== ====================
+
+To connect to *Modoboa*, first connect to the system and retrieve its
+current network address like this::
+
+  $ /sbin/ifconfig eth0
+
+Once you know its address, open a web browser and go to this url::
+
+  http://<ip_address>/modoboa/admin/
+
+You should see the login page. Here are the users available by default:
+
+================ ======== ============================================
+Login            Password Capabitilies
+================ ======== ============================================
+admin            password Default super administrator. Can do anything 
+                          on the admin but can't access applications
+
+admin@demo.local admin    Administrator of the domain *demo.local*.
+                          Can administrater its domain and access to 
+                          applications.
+
+user@demo.local  user     Simple user. Can access to applications.
+================ ======== ============================================
+
+Limitations
+===========
+
+Using this demo, you will be able to test almost every functionality
+*Modoboa* provides. The exceptions are listed below:
+
+* No spam quarantine: there is not any amavis setup on the machine. By
+  the way, you can still use this feature if you know any quarantine
+  available on your network.
