Finally I've designed answer-file creating ml2_conf.ini -> /etc/neutron/plugins/ml2/ml2_conf.ini, but plugin.ini -> /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini has been created manually exactly the same as ml2_conf.ini following http://kashyapc.fedorapeople.org/virt/openstack/rdo/IceHouse-Nova-Neutron-ML2-GRE-OVS.txt
Similar file has been created on Compute Node.
Metadata_agent.ini are the same on Controller and on Compute Nodes
Two boxes have been setup , each one having 2 NICs (p37p1,p4p1) for
Controller && Compute Nodes setup. Before running
`packstack --answer-file= TwoNodeML2&OVS&GRE.txt` SELINUX set to permissive on both nodes.Both p4p1's assigned IPs and set to support GRE tunnel (192.168.0.127, 192.168.0.137 ) between Controller and Compute Nodes. Services firewalld and NetworkManager disabled (after packstack completion), IPv4 firewall with iptables and service network are enabled and running. Packstack is bind to public IP of interface p37p1 192.169.1.127, Compute Node is 192.169.1.137 ( view answer-file ).
Setup configuration
- Controller node: Nova, Keystone, Cinder, Glance, Neutron (using Open vSwitch plugin && GRE )
- Compute node: Nova (nova-compute), Neutron (openvswitch-agent)
icehouse1.localdomain - Controller (192.168.1.127)
icehouse2.localdomain - Compute (192.168.1.137)

Similar file has been created on Compute Node.
Metadata_agent.ini are the same on Controller and on Compute Nodes
Two boxes have been setup , each one having 2 NICs (p37p1,p4p1) for
Controller && Compute Nodes setup. Before running
`packstack --answer-file= TwoNodeML2&OVS&GRE.txt` SELINUX set to permissive on both nodes.Both p4p1's assigned IPs and set to support GRE tunnel (192.168.0.127, 192.168.0.137 ) between Controller and Compute Nodes. Services firewalld and NetworkManager disabled (after packstack completion), IPv4 firewall with iptables and service network are enabled and running. Packstack is bind to public IP of interface p37p1 192.169.1.127, Compute Node is 192.169.1.137 ( view answer-file ).
Setup configuration
- Controller node: Nova, Keystone, Cinder, Glance, Neutron (using Open vSwitch plugin && GRE )
- Compute node: Nova (nova-compute), Neutron (openvswitch-agent)
icehouse1.localdomain - Controller (192.168.1.127)
icehouse2.localdomain - Compute (192.168.1.137)
