Hi, We are trying to setup OpenStack Icehouse by exactly following the documentation for Ubuntu 14.4.
http://docs.openstack.org/icehouse/install-guide/install/apt/content/basics-neutron-networking-network-node.html In the basic network configuration (neutron) stage, we set up the tunnel interfaces and management interfaces. In the network node, the doc says to leave the external network without IP. Then in the verification stage it is suggested to ping to some external node. But without IP, how can my external interface could communicate? Our OpenStack setup resides on a LAN. This is the present content of our /etc/network/interfaces file. The external network interface auto INTERFACE_NAME iface INTERFACE_NAME inet manual up ip link set dev $IFACE up down ip link set dev $IFACE down Are we supposed to do something to assign IP address to the external interface? In our LAN all the systems get IP through DHCP. Some Help/Hint/Suggestion is very much appreciated. Thanks a lot, Lloyd
