To add to first RE:

On compute node  192.168.1.137 :-

[root at dfw01 neutron]# cat plugin.ini
[ovs]
tenant_network_type = gre
tunnel_id_ranges = 1:1000
enable_tunneling = True
integration_bridge = br-int
tunnel_bridge = br-tun
local_ip = 192.168.1.137
[agent]
[securitygroup]
[DATABASE]
sql_connection = mysql://root:password@192.168.1.127/ovs_neutron
[SECURITYGROUP]
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver

It cannot work any longer affecting neutron-openvswitch service on compute node
I am using native F20 repos

It was never possible for me to start neutron-server with "mysql://neutron:fedora@hostname/ovs_neutron" . Starting as root causes some trouble, but it's acceptable.

Thanks.
Boris.
