Comment 2 for bug 1573538

I doubt it's a neutron issue since 8.0 should be regularly tested by out CI and the issue of a test VM not getting an IP or not getting connectivity (a very basic test!) should be instantly caught. So I suspect it's some configuration/deployment issue.

Please attach a diagnostic snapshot for further investigation. Please also describe your virtual network topology: networks, routers, VMs (with IDs) and the output of 'ovs-vsctl show'/'brctl show' from all controllers and compute nodes.
