Well, with regard to this point, I've done many different tests during the last
period actually, just to see how it behaves. I stated that if I give
too much RAM
to dom0, the system is unusable (~3-4GB, or ~7-8 for the laptop). If I
avoid to set
such parameter, the amount of free RAM is random! One time I can get 3 or 4 GB
free (for my desktop PC with 4GB of RAM) or 300MB free, or some other random
value.

LOL, of course! :-)
