Instance does'n get IP.
Hello, I know it may seem duplicate question, but in fact its not. I have a 4 node openstack in a real deployment, one controller and 3 computes. I have added another 6 compute nodes. On new compute nodes, instance launches successfully, and in dashboard it shows that instance gets IP, but inside the instance there is no IP assigned to it, "ip a" shows no IP and when I ping it through router, it in not reachable. inside the instance obviously "Network is unreachable" too, since no IP is assigned to it. The weird thing is that while launching the instance, there is no error log in controller and compute. The way I used for adding the new computes, is that I installed packages: openstsack-nova-compute, openstack-selinux, openstack-neutron, openstack-neutron-openvswitch on new computes. then I copy configuration files : nova.conf , neutron.conf, openvswitch-agent.ini from a properly working compute node, to the new ones. then I changes IP addresses and hostnames, plus chown of files, accordingly. after that start and enable the services.
Any help would be extremely appreciated.
