Changing node for compute. Openstack kilo release ubuntu 14.0.4

Question

I have 3 nodes: controller, compute1 and network.

Unfortunately network had 72 GB RAM and compute only 16. I wanted to change them

Installed fresh Ubuntu 14.04 on each of them (controller haven't touched).

After installing nova-compute and making proper setting it cannot connect to rabbitmq. I've recreated database for nova. Not helped. Error is that Compute host compute1 cannot be found.

Do I need to change something in rabbitmq-server or smth else on controller node?

The problem is that developers changed repositories for some components and you need to add them to every node.....
