Hi Gianpietro,

Thanks for reaching out.

As I was adding the contents of ml2_conf.ini to reply to you, I noticed
my missing configuration for [ml_type_vlan] for the network_vlan_ranges

I placed that in and re-popluated the database and I can at least now
receive a ping reply from the instances.

Thanks!
