Hi all,

I have succesfully deployed an AIO Devstack (Icehouse) with Neutron and OVS on a Ubuntu 14.04. Main problem I have is network configuration. Althought I have read tones ofarticles, questions, Im still stuck on it...

https://ask.openstack.org/en/question/11172/devstack-networking-for-standalone-virtualbox-vm-cant-ping-tofrom-instances/ (https://ask.openstack.org/en/question...) https://ask.openstack.org/en/question/11446/devstack-instance-not-reachable-on-virtualhost-with-nat/ (https://ask.openstack.org/en/question...) https://ask.openstack.org/en/question/35100/cannot-access-instance-with-assigned-floating-ip/ (https://ask.openstack.org/en/question...) http://openstack.redhat.com/Networking

The host public network is 10.7.6.0/24. I have to NICs in my machine.

My local conf is:

[[local|localrc]]
APACHE_ENABLED_SERVICES+=keystone
LOGFILE=$DEST/logs/stack.sh.log
disable_service n-net
enable_service q-svc
enable_service q-agt
enable_service q-dhcp
enable_service q-l3
enable_service q-meta
enable_service neutron
HOST_IP=10.7.6.41
FLOATING_RANGE=10.7.6.0/24
Q_FLOATING_ALLOCATION_POOL=start=10.7.6.224,end=10.7.6.254
FIXED_RANGE=10.0.0.0/24
FIXED_NETWORK_SIZE=256
FLAT_INTERFACE=eth0
ADMIN_PASSWORD=password
MYSQL_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
SERVICE_TOKEN=tokentoken

This is my host network config:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

    link/ether 42:a9:87:5c:bd:35 brd ff:ff:ff:ff:ff:ff
6: br-int: <BROADCAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN group default

    inet 10.7.6.42/24 scope global br-ex
       valid_lft forever preferred_lft forever

I have manually configured br-ex to be attached to eth1, my non IPed NIC.

sudo ip addr flush eth1
sudo ovs-vsctl ...
