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?
