Hi Liu,

If you created a new neutron database and used you're existing nova
database you would definitely lose the network interfaces on the
nova-compute side if you rebooted your instances. You should use the
original database and perform a db migration to upgrade to havana: see:
https://github.com/openstack/neutron/tree/master/neutron/db/migration

A possible other work around would be to use nova's interface-attach to add
interfaces to your existing vms that you've already spinned up.
