If you experience problems trying to setup one of these RDF engines, you can download and try the prebuilt VM disk images from Athena's FTP directory at: 
29 3 Giorgos Giannopoulos
30 3 Giorgos Giannopoulos
ftp://guest@geoknow-server.imis.athena-innovation.gr/
31 3 Giorgos Giannopoulos
32 3 Giorgos Giannopoulos
Use guest:be-my-guest when prompted for your credentials and login to the FTP account.
33 3 Giorgos Giannopoulos
34 3 Giorgos Giannopoulos
These images are normal XEN domU disk images, that can be used to create a functional domU guest. Of course, you should also provide:
35 3 Giorgos Giannopoulos
* your own guest configuration file at <code>/etc/xen/<the-vm>.cfg</code> (or wherever you have chosen to configure your domU guests)
36 3 Giorgos Giannopoulos
* a swap image file
37 3 Giorgos Giannopoulos
38 3 Giorgos Giannopoulos
Use root:root as the root password for your newly created machine (and of course, change it just after your first login)
39 3 Giorgos Giannopoulos
40 3 Giorgos Giannopoulos
After creating the machine, you should login with the serial console (eg. <code>xm console <the-vm></code>) and:
41 3 Giorgos Giannopoulos
* configure your network interfaces to adapt to your local network
42 3 Giorgos Giannopoulos
* configure your hostname and your <code>/etc/hosts</code> file
