Title:
  VM fails to get IP with shared network

Status in OpenStack Compute (Nova):
  Invalid

Bug description:
  VM fails to get IP with shared network.

  I created shared network with the following command with admin account.
  quantum net-create private-net-01 --provider:network_type flat --provider:physical_network private-net-01 --shared

  However, tenant(other than admin)'s VM with the shared network fails
  to get IP from DHCP server.

  I found that nova sets incorrect filter rule for DHCP in compute node's iptables.
  172.27.0.2 was the actual DHCP server's address.
