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

Hello,<br>
<br>
I'm attempting to get rdo working on Centos6.5 with external
networking. I am following the steps outlined on <a
moz-do-not-send="true" class="moz-txt-link-freetext"
href="http://openstack.redhat.com/Neutron_with_existing_external_network">http://openstack.redhat.com/Neutron_with_existing_external_network</a><br>
<br>
To install openstack, I'm running the following commands:<br>
<br>
<blockquote> sudo yum -y update<br>
sudo yum install -y <a moz-do-not-send="true"
class="moz-txt-link-freetext"
href="http://rdo.fedorapeople.org/rdo-release.rpm">http://rdo.fedorapeople.org/rdo-release.rpm</a><br>
sudo yum install -y openstack-packstack<br>
packstack --allinone --provision-all-in-one-ovs-bridge=n
--os-client-install=y --os-heat-install=y<br>
</blockquote>
<br>
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:<br>

When I go to look for br-tun I do 'ovs-vsctl show' and I'll
*sometimes* see:<br>
<blockquote>...<br>
Bridge br-tun<br>
Port br-tun<br>
Interface br-tun<br>
type: internal<br>
...<br>
</blockquote>
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.)<br>

Any help would be appreciated.<br>
