Hi everybody
Following the quickstart guide of xen I can only use para-virtualized guests because my Asus A8V Deluxe mainboard with AMD 64 bit processor does not have the svm flag. Can anyone tell me the difference between Para- and Fully-virualized guests ? What are the limitations of a system that only supports para-virtulazed guests ?

A fairly technical overview is here:

Fully-virtualized can (in theory) run any OS ever written.
Para-virtualized can only run OS which have been ported to Xen (eg Linux and some varities of Solaris & BSD)
At this time, paravirtualized is significantly faster than fullvirt so if you have the option paravirt is always preferred. With Windows of course you don't have that option - fullvirt is only choice.
