Hi Shi,

I changed the name of the Ethernet device inside of the configuration file as you suggest, using br0 instead of eth0, but it didn't help.
Now, I have a doubt:
if I use the hook scripts (the ones in one/share/hooks/ in the last opennebula release) (as actually I'm trying to do)
have I to set-up a bridged network? I mean more than what is written here http://www.opennebula.org/doku.php?id=documentation:rel1.4:nm
or I have only to change some of the setups, that I have already done following the guide? I wouldn't interferer with the scripts changing the network topology. 
Many tanks,

Gianni.

Thank you Fernando for the information,
Anyway I forget to say I have already changed that lines.
