Hi All,
I have seen several people asking how to set up openstack on a machine with a
single nic card. I have created a blog page for the same. The blog includes
aome information about openstack networking also.

Ageeleshwar,
Do you happen to have a devstack local.conf for this specific setup?
That would be of great help to everyone i believe.

I have gre tenant networks and one single flat network that I use as my
external network. I created a router and connected to the tenant networks and
to the flat external network and every thing is working fine.
Have you attached a router to your flat network and to your gre network?
Icehouse works perfect on 14.04. Please follow the official install guide.
Thank you,

let me give you a few leads.
1. Check the mysql connection string inside /etc/neutron/neutron.conf and see
if it is valid.
2. Check the keystone_authtoken section inside the same file and verify if they
are correct and if the specified user/tenant(neutron/service) is

See how you create an external network if you haven't already.
Once an external network is created in openstack, instances launched in that
network can be accessed directly.

Perfectly possible. In fact that is what I have done too. In openstack the
network node is nothing but a machine which has the below three installed.
1. neutron-l3-agent
2. neutron-dhcp-agent
3. neutron-openvswitch-agent
The compute node is what which contains
1. nova-compute
2.
option 1
bridge all traffic from br-ex and br-eth1 to one physical interface eth1
eth0 -- Internal network
br-eth1 -- Data network(physnet1 may be)
br-ex -- External network
in addition to the above add br-proxy
ovs-vsctl add-br br-proxy
ovs-vsctl add-port br-proxy eth1
ip link set eth1 up
This is not very informative.
I'll give you a suggestion.
Open up the log file(tail -f /var/log/nova/nova-compute.log) . Then launch an
instance. Send only the errors that show up during the launch.
Also I would like to see error in scheduler and nova-api .

Hi,
Your first hop is keystone project. It is the openstack identity management
