Xen Virtualization on Linux and Solaris: September 2013

Follow as normal http://openstack.redhat.com/Neutron-Quickstart

When done switch to eth0 per
http://unix.stackexchange.com/questions/81834/how-can-i-change-the-default-ens33-network-device-to-old-eth0-on-fedora-19

Remove biosdevname if it is installed. (yum remove biosdevname)
Disable the udev rule: ln -s /dev/null /etc/udev/rules.d/80-net-name-slot.rules
Reboot

and create under /etc/sysconfig/network-scripts

[root@localhost network-scripts]# cat ifcfg-br-ex

Enable network service

REBOOT

Turn off interface eth0 , update ONBOOT="no" to ONBOOT="yes"
in ifcfg-eth0, then restart network service

In dashboard environment delete router1 and public network.

Create router2 and internal interface to private network.

#   source keystonerc_admin
#   nova secgroup-add-rule default icmp -1 -1 0.0.0.0/0
#   nova secgroup-add-rule default tcp 22 22 0.0.0.0/0
#   quantum net-create public --router:external=True
#   quantum subnet-create public 192.168.1.0/24 --name vlan \

--enable_dhcp False --allocation_pool \

start=192.168.1.57, end=192.168.1.62 \
--gateway 192.168.1.1
# quantum floatingip-create public

Next step

# EXTERNAL_NETWORK_ID=`quantum net-list | grep public | awk '{ print $2 }'`
# quantum router-gateway-set router2 $EXTERNAL_NETWORK_ID
# INT_SUBNET_ID=`quantum subnet-list | grep private_subnet | awk '{ print $2}'`
# quantum subnet-update $INT_SUBNET_ID --dns_nameservers list=true 83.221.202.254
# quantum subnet-update $INT_SUBNET_ID --gateway_ip 10.0.0.1

Router2 and internal interface to private network may be also created via CLI:

# EXTERNAL_NETWORK_ID=`quantum net-list | grep public | awk '{ print $2 }'`
# INT_SUBNET_ID=`quantum subnet-list | grep private_subnet | awk '{ print $2}'`
# SERVICE_TENANT_ID=`keystone tenant-list | grep service | awk '{ print $2}'`
# quantum router-create --name router2 --tenant-id $SERVICE_TENANT_ID router2
# quantum router-gateway-set router2 $EXTERNAL_NETWORK_ID
# quantum router-interface-add router2 $INT_SUBNET_ID
# quantum subnet-update $INT_SUBNET_ID --dns_nameservers list=true 83.221.202.254
# quantum subnet-update $INT_SUBNET_ID --gateway_ip 10.0.0.1

Attempting to follow http://allthingsopen.com/2013/08/23/openstack-packstack-installation-with-external-connectivity/I've got an error after starting :-
# packstack --allinone --quantum-l3-ext-bridge=eth0
It reports that ovs port eth0 already exists. Approach bellow in general follows RDO's discussion

REBOOT
Disable autoconnect eth0.

Remove old puplic (external network) and create new one as required.
Recreate router in dashboard environment and add internal interface to
private network
