A: More than likely, you’ve looped your network. Probably, eth0 and eth1 are connected to the same physical Ethernet switch. This yields a scenario where OVS receives a broadcast packet on eth0 and sends it out on eth1, then the physical switch connected to
eth1 sends the packet back on eth0, and so on forever.</div>
