Thanks for your answers!
Setting fail-mode to secure worked great...Anyway it was just to
understand...Since now I'll set up OVS with default options (standalone)...
Answering to Ozaki...I just use two nics on my OVS (eth1 and eth2) +
eth3 for management, and one nic per host attached..
Does anyone of you know what's the classifier table? What's the
difference between that particular table and the others?
