Not a bug.. upgraded to OVS 2.0 and it all works, so likely an issue
with OVS old version.

Title:
  neutron ovs plugin doesn't work in multi-node setup

Status in OpenStack Neutron (virtual network service):
  Invalid

Bug description:
  Rules for cross-node traffic are not set up properly.

  For example on br-tun, I have the following rules:
  cookie=0x0, duration=1349.118s, table=0, n_packets=37, n_bytes=3490, priority=1,in_port=1 actions=resubmit(,1)
  cookie=0x0, duration=1347.769s, table=1, n_packets=37, n_bytes=3490, priority=0,dl_dst=01:00:00:00:00:00/01:00:00:00:00:00 actions=resubmit(,21)
  cookie=0x0, duration=1345.371s, table=21, n_packets=37, n_bytes=3490, priority=0 actions=drop

  The first one takes the packet from br-int into br-tun, and jumps to
  table 1 (PATCH_LV_TO_TUN). Table 1 redirects the packets to table 21
  (FLOOD_TO_TUN), and table 21 has a single drop rule.

  It seems that a few rules should be inserted to actually broadcast the
  packets via available tunnels to other nodes.
