deployed a mutil-node env using kolla and trying to use fake driver but failed

I deployed a mutil-node env using kolla, with enable_nova_fake=yes trying to use fake driver. The deployment was successful but the network related containers of controller and compute node kept restarting state.

The version:
ansible 2.4.2.0
kolla-ansible 6.0.0.0b3
openstack pike
Docker version 1.12.5

The result is:
