Ok I think I figured out where the real problem is, but I can't solve it.

Problem is related to the connection to the iscsi disks.

Looking into logs I get:

internal error: Child process (/usr/bin/iscsiadm --mode session) unexpected exit status 21

this leads to whole virsh hang!

Indeed, I tried to remove the "storage" directory from /etc/libvirt and restarted the service: everything worked!

And if I added manually the iscsi targets everything keeps working.

But, if I restart the service once again, virsh hangs! And that error shows up!

netstat -lptu
gives me
tcp6 0 0 [::]:16514 [::]:* LISTEN 1314/libvirtd

so the server is correctly listening on interfaces.

My /etc/libvirt/libvirtd settings are defaulted.
My /etc/default/libvirt-bin has "-d -l" options so server is listening.

If I do virsh -c qemu://143.225.229.190/system (that is my ip or an ip belonging to my network) I get "connection refused".

How come?
And note that if I put my address, 143.225.229.190, as listening address in the libvirtd conf file, I get "this address class is not supported".
