[Rdo-list] Neutron configuration files for a two node Neutron+GRE+OVS

Heya, Just in case if it's useful for someone, here are my working Neutron configuration files (and iptables rules) for a two node set-up based on IceHouse-M2 on Fedora-20, - Controller node: Nova, Keystone (token-based auth), Cinder, Glance, Neutron (using Open vSwitch plugin and GRE tunneling). - Compute node: Nova (nova-compute), Neutron (openvswitch-agent) Controller node Neutron configurations ====================================== 1. neutron.conf --------------- $ cat /etc/neutron/neutron.conf | grep -v ^$ | grep -v ^# [DEFAULT] core_plugin =neutron.plugins.openvswitch.ovs_neutron_plugin.OVSNeutronPluginV2 rpc_backend = neutron.openstack.common.rpc.impl_qpid control_exchange = neutron qpid_hostname = 192.169.142.49 auth_strategy = keystone allow_overlapping_ips = True dhcp_lease_duration = 120 allow_bulk = True qpid_port = 5672 qpid_heartbeat = 60 qpid_protocol = tcp qpid_tcp_nodelay = True qpid_reconnect_limit=0 qpid_reconnect_interval_max=0 qpid_reconnect_timeout=0 qpid_reconnect=True qpid_reconnect_interval_min=0 qpid_reconnect_interval=0 debug = False verbose = False [quotas] [agent] [keystone_authtoken] admin_tenant_name = services admin_user = neutron admin_password = fedora auth_host = 192.169.142.49 auth_port = 35357 auth_protocol = http auth_uri=http://192.169.142.49:5000/ [database] [service_providers] [AGENT] root_helper = sudo neutron-rootwrap /etc/neutron/rootwrap.conf 2.
