I would also recommend you create third VM3 for compute node, rather then use Controller && Network Nodes as Compute Nodes. You may have a look at

One more notice I am not sure Oracle Linux 6.6 as clone of RHEL 6.6 would work with Juno.
Anyway as OS installed on VMs it would better to be replaced by CentOS 7, which is well tested with Juno packstack installs many times.

You also posted tag "devstack-neutron" . What you mean by that ?
