Hi, I deploied a 3 nodes OpenStack Essex, 1 controller node and 2 compute nodes. Each node has two NIC.

On the compute nodes I installed nova-compute and nova-network. Part of the content in the nova.conf file is like(this part is the same in all the 3 nodes):

public_interface=eth0 flat_interface=eth1 flat_network_bridge=br100 fixed_range=10.42.0.0/24 flat_network_dhcp_start=10.42.0.33 multi_host=true

So the problem is, where should I create my network(run nova-network private create), in the controller or in each compute node? Or both would work?

Thanks!
