+====== Openstack HAVANA Installation and Configuration ======
+Authors: Eric Frizziero (INFN Padova), Lisa Zangrando (INFN Padova)
+==== Description ====
+This guide provides the step-by-step installation and configuration procedure of Openstack HAVANA in //allinone// mode.
+In particular the setup requires just a physical host (i.e. gilda-11.pd.infn.it) having two physical network cards (eth0 and eth1).
+The "eth0" (ip: 193.206.210.223) is used for accessing the external network while the "eth1" (ip: 192.168.132.122) is used for accessing  the internal network.
+The Openstack framework is installed in a SL6 environment by using the packstack tool with the specific (i.e. local) network type to allocate tenant networks.
+==== Prerequisites ====
+   * OS: SL6
+   * EthernetCard: eth0, eth1
+==== Installation of repositories ====
+<code bash>
+rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
+yum install -y http://rdo.fedorapeople.org/rdo-release.rpm
+yum clean all; yum update
+</code>
+==== Disable the yum-autoupdate ====
+<code bash>
+rpm -e --nodeps yum-autoupdate-2-5.2.noarch
+</code>
+==== RPMs installation ====
+<code bash>
+yum install -y openvswitch.x86_64
+yum install -y openstack-neutron-openvswitch.noarch
+yum install -y openstack-packstack
+reboot
+</code>
+==== Host Network configuration ====
+=== Configure the ethernet card "eth0" ===
+<code bash>
+cat /etc/sysconfig/network-scripts/ifcfg-eth0
+DEVICE="eth0"
+TYPE=OVSPort
+DEVICETYPE=ovs
+OVS_BRIDGE=br-ex
+ONBOOT=yes
+#PROMISC="yes" if VLAN is used
+</code>

+==== Openstack installation ====
+This is the packstack-answers-file.txt used: {{:progetti:cloud-areapd:packstack-answers-file.txt|}}
+<code bash>
+packstack --answer-file=packstack-answers-file.txt
+</code>
+Note: used the property //CONFIG_NEUTRON_LB_TENANT_NETWORK_TYPE=local// in packstack-answers-file.txt
+==== Openstack configuration ====
+The services nova-api and the nova-metadata-api are both using the same port, 8775. Thus, the services are 'competing' for the port and one of them will not work (see: [[https://bugzilla.redhat.com/show_bug.cgi?id=1017058]])
+It is necessary to execute the following steps (see:[[ http://openstack.redhat.com/forum/discussion/comment/913]]):
+Edit /etc/nova/nova.conf to remove "metadata" from "enabled_apis" variable so it should be:
+<code bash>
+enabled_apis=ec2,osapi_compute
+</code>
+Restart the nova-api and nova-metadata-api services:
+<code bash>
+service openstack-nova-api restart
+service openstack-nova-metadata-api restart
+chkconfig openstack-nova-metadata-api on #auto start nova-metadata-api on boot
+</code>
+If you tried to start openstack-nova-metadata-api before editing nova.conf you may need to do:
+<code bash>
+rm -f /var/lock/subsys/openstack-nova-metadata-api
+rm -f /var/run/nova/nova-metadata-api.pid
+service openstack-nova-metadata-api restart
+</code>
+=== dhcp_agent.ini configuration ===
+Edit /etc/neutron/dhcp_agent.ini and set the following properties:
+<code bash>
+enable_isolated_metadata = True
+enable_metadata_network = True
+</code>
+Restart Neutron services
+<code bash>
+service neutron-dhcp-agent restart
+service neutron-openvswitch-agent restart
+</code>
+=== ovs_neutron_plugin.ini configuration ===
+This step is needed only if the packstack property //CONFIG_NEUTRON_LB_TENANT_NETWORK_TYPE=vlan// is used.
+Edit /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini and set the following properties:
+<code bash>
+network_vlan_ranges = physnet1
+bridge_mappings = physnet1:br-ex
+</code>
+Restart Neutron services
+<code bash>
+service neutron-dhcp-agent restart
+service neutron-openvswitch-agent restart
+</code>
