Hi Gianluca,

Here is my testbed setup:



Browser (firefox 24.2.0)                              ovirt-engine (3.3.2)                                        host (ovirt-node)
 10.10.2.143        -------------------  eth0: 10.10.36.103       eth1: 169.254.11.13  ------------------- 169.254.103.2 
                                                      (I stopped iptables in testing)
      


Which log files are needed to examine what's wrong?
