Legacy networking primarily involves compute nodes. However, you must configure the controller node to use it.
To configure legacy networking
Run the following commands:
# openstack-config --set /etc/nova/nova.conf DEFAULT \ network_api_class nova.network.api.API # openstack-config --set /etc/nova/nova.conf DEFAULT \ security_group_api nova
Restart the Compute services:
# service openstack-nova-api restart # service openstack-nova-scheduler restart # service openstack-nova-conductor restart
