# packstack --allinone --quantum-l3-ext-bridge=eth0
It reports that ovs port eth0 already exists. Approach bellow in general follows RDO's discussion
at http://openstack.redhat.com/forum/discussion/196/quantum-basic-setup/p1
Follow as normal http://openstack.redhat.com/Neutron-Quickstart
When done create under /etc/sysconfig/network-scripts
[root@Server64 network-scripts]# cat ifcfg-br-ex

Run script as root :-

# chkconfig network on
REBOOT
Disable autoconnect eth0.
REBOOT
Remove old puplic (external network) and create new one as required.
Recreate router in dashboard environment and add internal interface to
private network
