Hi, I am openstack newbie. I am using neutron as network service and tried various network configurations for over 2 weeks now and none of them work. Networking works fine for juju deployment. After that I am not sure how to configure neutron. I have a basic setup of 5 servers. 1 server is hosting kvm vms (MAAS controller and juju controller). The other 4 servers are nodes. Network configuration: The controllers each have 2 dedicated (passthrough) interfaces (1 1G and 1 10G). Each of the nodes have 4 interfaces (2 1G and 2 10G). All the 1G interfaces are connected to a single switch with access to internet(10.20.x.x). All 10G interfaces are connected to a switch acting as internal network (192.168.x.x). I PXE boot from this network. There are no vlans on any of the switches. I would like to have all my vms talking to each other via internal network and have floating IPs to access the external world. How do I go about configuring my MAAS and juju networks? Any help would be greatly appreciated. Thanks!

What are the interfaces registering their names as in MaaS? I believe they need to be eth#.

Check that first, then can you clarify what you mean when you said Networking works fine for juju deployment, when you deploy the controller? or it deploys to all the hosts too and works.

Hi I have resolved the issue for now by using spaces on MAAS and using bindings on charms and associating them to network spaces. This allows me to specify on which network I can have the external network associated to a network space and keep this space free from being used for other services.
