Could you please provide the following data. Otherwise it's hard
debugging anything via mail:
# Authenticate to your cloud [1] and then run the following command to
show all the details of your external network:
> neutron net-show home
#Run these commands to collect more information about your host setup
> ovs-vsctl show
> ip a
> ps -ax | grep neutron-
> cat /etc/neutron/plugin.ini
> cat /etc/neutron/plugins/ml2/ml2_conf.ini
