Another strange thing. I tried, in order to solve this, to put my hostname as listening address.
I started with the ip, 192.168.2.2, and it works.
I then decided to use the domain name, pasquale-Dell, but the socket is not created.
Looking into logs it seems it tries to resolve the name, without success. After a lot of tries it just decides to give up. However, in file /etc/hosts the resolution is correctly set and I can just think that libvirt starts before the name discovery system is actually up.
The fact the daemon is not started at all confirms this.
But now here's the moment I begin to HATE libvirt.
You would expect that executing service libvirt-bin start (or restart) would solve this, right?
Well, if I do that the deamon correctly starts...but libvirt hangs!!
Every connect I try with virsh, let it be local or remote, just hangs indefinitely.
The is no *censored* way to restart the libvirt daemon: it just leads to hang.
The only *censored* way to restart it is to restart the whole system and pray libvirt starts after the name resolution.
