Hello Corrado,

per rendere tutti partecipi del problema ti rispondo in inglese. Non me 
ne volere per questo... :)

So, your problem can be summarized with the following sentence: whenever 
you try to start virtual machines all you get is a set of running 
processes but no consoles.

You say the pair of arguments "con0=xterm quiet" looks questionable, but 
it is not. "con0=xterm" tells the UML kernel to launch an xterm and to 
attach the primary console of the virtual machine to it. "quiet" 
instructs the UML kernel to limit the verbosity of the messages during 
the boot phase. Anyway, they are separate arguments (you should not 
interpret them as "launch a quiet xterm for console 0").

Since the UML kernel is correctly started, this problem may be related 
to unavailability of the xterm emulator (try running "xterm" alone and 
see what happens), but this is only a very rough guess. In order to 
better diagnose the problem, it would be useful for me to see what is 
the output of "vstart vm1 --new --verbose --noxterm".
