Hello all!

Trying to setup a simple (lol simple..) openstack single node 
configuration for testing. Been up and down and all around networking 
and noting seems to make sense or works.

rpm -qa | grep openstack
openstack-swift-object-1.4.8-2.el6.noarch
openstack-swift-doc-1.4.8-2.el6.noarch
openstack-glance-2012.1-5.el6.noarch
openstack-dashboard-2012.1-4.el6.noarch
openstack-swift-container-1.4.8-2.el6.noarch
openstack-swift-proxy-1.4.8-2.el6.noarch
openstack-keystone-2012.1-3.el6.noarch
openstack-nova-2012.1-4.el6.noarch
openstack-swift-1.4.8-2.el6.noarch
openstack-swift-account-1.4.8-2.el6.noarch
openstack-quantum-2012.1-4.el6.noarch
openstack-utils-2012.1-1.el6.noarch

Current attempt is to mirror the configuration shown here 
http://unchainyourbrain.com/openstack/13-networking-in-nova.

network configuration

eth0 [public]:
DEVICE="eth0"
BOOTPROTO="static"
NM_CONTROLLED="no"
ONBOOT="yes"
IPADDR=137.143.102.116
GATEWAY=137.143.110.254
NETMASK=255.255.240.0

eth1 [private]: (tried with and without assigning an IP)
DEVICE="eth1"
MTU="1500"
ONBOOT=yes
NM_CONTROLLED="no"
IPADDR=192.168.0.1
NETMASK=255.255.255.0

nova.conf
network_manager = nova.network.manager.FlatDHCPManager
fixed_range=10.200.0.0/24
flat_network_dhcp_start=10.200.0.2
flat_network_bridge=br100
flat_interface=eth1
flat_injected=False
public_interface=eth0

brctl:
bridge name     bridge id               STP enabled     interfaces
br100           8000.000000000000       no
virbr0          8000.525400e396a2       yes             virbr0-nic

created nova network via:
nova-manage network create demonet 10.200.0.0/24 1 256 --bridge=br100

It is my understanding that nova-network _should_ configure br100 and 
all the other network bits, correct? if so, then something is just not 
right in my config seeing that nova-network does not configure anything 
with br100 or eth1.

Anyone see where I went wrong?

Regards,

Ron
