Hello,
I'm attempting to get rdo working on Centos6.5 with external networking.
I am following the steps outlined on
http://openstack.redhat.com/Neutron_with_existing_external_network
To install openstack, I'm running the following commands:
sudo yum -y update
sudo yum install -y http://rdo.fedorapeople.org/rdo-release.rpm
sudo yum install -y openstack-packstack
packstack --allinone --provision-all-in-one-ovs-bridge=n
--os-client-install=y --os-heat-install=y
After it completes I do 'tail -f /var/log/neutron/*.log' and then
'service neutron-openvswitch-agent restart'. In the neutron log I see
the following errors:
2014-07-18 16:06:03.255 28794 ERROR neutron.agent.linux.ovs_lib

When I go to look for br-tun I do 'ovs-vsctl show' and I'll *sometimes* see:
...
Bridge br-tun
Port br-tun
Interface br-tun
type: internal
...
Now, this is kind of weird, but if I do "watch -n 0.5 ovs-vsctl show" I
don't always see br-tun! In fact the br-tun seems to jump around a lot
(sometimes its there, sometimes its listed above br-ex, sometimes below.)
More info:
[root@localhost ~]# ovsdb-server --version

Any help would be appreciated.

From here[1], the above seems (at-least on Ubuntu machines) like an
incompatibility between OVS (1.10.2) and Kernel (3.11.0-20). But I see
from below that you're using OVS 1.11.0.
I don't have a 6.5 machine handy to check. You might want to ensure
you have whatever newest Kernel/OVS/openstack-neutron packages available
for CentOS 6.5 RDO.
Also, here's some configs that worked for me w/ IceHouse+Neutron+GRE on
Fedora-20 RDO.

Found a fix for this:
rm /etc/sysconfig/network-scripts/ifcfg-br-tun
(restart neutron networking services and nova-compute)
Apparently that file shound't exist. The flapping may have been due to
openvswitch and the underlying system fighting for control of the interface.
