Hi, I had an allinone setup of RDO openstack which is running fine (IP =172.18.50.200 on enp17s0) on fedora 21 machine. I am plannning to add a compute node and for that I connected NIC 2 (IP = 192.168.0.1,enp13s0) of controller machine to another (which I want to make compute) machine (IP = 192.168.0.2, enp3s1) and enabled NAT to access internet. I am able to ssh to the both the machines from either ones. Started packstack with answer file and it completed successfully. But I am not able to spawn VMs. /var/log/nova/nova-compute.log throws "NeutronClientException: 404 Not Found" I suspect the issue is because answer file is not corretly configured. Please find the attached answer file and suggest what should be the correct entries esp. under fields CONFIG_NOVA_COMPUTE_PRIVIF CONFIG_NOVA_NETWORK_PRIVIF CONFIG_NOVA_NETWORK_PUBIF Regards, Saurav
