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!

I assume you are using nova networking. Please go through the FlatDHCP networking models. Nova network component should be on compute node as well as controller node. You can run the 'nova-manage network create'command on controller node only & verify network creation using 'nova-manage network list'
