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.

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:

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:

Any help would be appreciated.
