Hi,
As I told you, I have also a problem for instance IP assignement. My architecture : I use Quantum with OVS plugin on 2 servers Essex-1 & Essex-2. Essex-1 runs all services and Essex-2 runs OVS, Quantum-agent & nova-compute only. You can see more details here. My configurations files are here and in my documentation. Problem Description : When an instance is created in ESSEX-1, all is working (network). But when the VM is started on ESSEX-2, it does not get an IP address. (log file) I'm sure the problem comes from OVS connection with ESSEX-1. Do I need to configure something like a trunk or a tunnel between Essex-1 & Essex-2 ? I miss something in my configuration, if you have any idea...
