Thanks. I replied myself, trying to provide some more information about
what's going on...

I'm not even sure whether xend is running or not! :-( As I wrote there,
even when I only see the xend status check, I have xm working, which
shouldn't happen without a proper xend running, right?

Moreover, independently from whether I install the package or not, or
whether I kill/start xend manually, it looks indeed like the libxl
driver is not able to load itself.

Where should I look for the libvirtd logs you're mentioning? I've
checked in /var/log/libvirt/* and in /var/log/messages, without finding
anything interesting. Should I look somewhere else? Should I pass
additional parameter to any of the involved components?

Thanks again and Regards,
Dario
