Hi there!

I am new to openstack and i followed the installation guide of icehouse for ubuntu 12.04/14.04

I chose 3 node architecture. Controller, Nova, Neutron.

The 3 nodes are installed in VM's. I used nested KVM. Inside VM's kvm is supported so nova will use virt_type=kvm. In controller i created 2 nics. eth0 is a NAT interface with ip and eth1 a host only interface with ip

In nova there are 3 nics. eth0 NAT -, eth1 host only and eth2 another host only

In neutron 3 nics. eth0 NAT, eth1 host only and eth2 another hosty only (during installation guide in neutron node i created a br-ex (and a port to eth0) which took the settings of eth0 and eth0 settings are:

auto eth0 
iface eth0 inet manual 
up ifconfig $IFACE up  
up ip link set $IFACE promisc on  
down ip link set $IFACE promisc off   
down ifconfig $IFACE down)

Everything seemed fine. I can create networks, routers etc, boot instances but i have this error.

When i launch an instance it takes a fixed ip but when i log in into instance (cirros) cant ping anything. ifconfig with no ip.

I noticed that in demo-net (tenant network) properties under subnet in the ports field it has 3 ports. network:router_interface active network:dhcp active compute:nova down

I searched for solutions over the net but couldn't find anything!

Any help?

Ask me if you want specific logs because i dont know which ones to post!

Thanx anyway!
