Hi Nicolas,
You need another interface ( say eth1 UP & running ) . Configure br100 to
use eth1 .
typically your configuration will look like the below ..
/etc/network/interfaces
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
allow-hotplug eth0
iface eth0 inet dhcp
auto eth1
auto br100
iface br100 inet static
bridge_ports eth1
address 10.0.0.1
netmask 255.255.255.0
bridge_stp off
bridge_fd 0
nova.conf will have the following lines too..
--fixed_range=10.0.0.0/24
--network_size=256
--network_manager=nova.network.manager.FlatManager
--flat_interface=eth1
--flat_injected=False
--public_interface=eth0

Subject: [Openstack] Instance can't reach dhcp or metadata
Hi stackers,
I got, using devstack, openstack running. I can launch instance correctly (as
seen in horizon state) but the instance can't reach the dhcp or the metadata.
Here the topology (as it should be, but I maybe need to configured otherwise in
the conf) of my server (one box only) :
* router : 192.168.23.1
* server
* ip : 192.168.23.5 (with dhcp but always the same)
* interface with external (network and internet) : eth0
* interface for openvswitch bridge : br100
* interface for nova/quantum/melange bridge : br100
* openstack
* glance with file backend
* quantum and melange for networking
* openvswitch as plugin
You can find all the config files and log here :
https://gist.github.com/2342747.
And networking info below.
Any tips, or pointing misconfiguration will be very appreciated.
