Begin new lib/neutron Background for this work can be read on the mailing list: http://lists.openstack.org/pipermail/openstack-dev/2016-May/094063.html Usage of the new Neutron is by setting the following in ENABLED_SERVICES: * neutron-api * neutron-l3 * neutron-agent * neutron-dhcp * neutron-metadata-agent For now, the new neutron library supports just the ML2 plugin, with the Open vSwitch and Linux Bridge agents supported. All other Neutron plugins should be creating their own DevStack plugin if they wish for DevStack to support them. Many of them already do. Other notable changes compared to neutron-legacy: * Rely on the Neutron defaults, and force Neutron to make sane defaults instead of all kinds of knobs in DevStack. * Default to rootwrap daemon support * Use the security group driver by default * interface_driver can now use NEUTRON_AGENT (linuxbridge, openvswitch), since they are entrypoints in neutron's setup.cfg * Use NEUTRON_AGENT variable to determine which agent to run Works with NEUTRON_AGENT set to either "linuxbridge" or "openvswitch" Default is openvswitch for the time being. * Set ML2 configuration for VXLAN support * Remove Xen hypervisor stuff - it should be a plugin * Move L3 crud into separate service file: There's a lot of L3 configuration that was in the main neutron file, but a lot of it is self contained and can be moved into its own file. The new l3 service file will contain all the previous L3 plumbing and configuration that the OpenStack Gate expects, while also eventually moving the whole l3 network creation step into a single hook that can be overridden by plugins. * Introduce a check for a function "neutron_plugin_create_initial_networks" which will become the mechanism through which different topologies, and networking plugins can create and wire the initial networks that are created during a stack.sh run. The new lib/neutron is considered experimental, and followup patches will build upon this one. Existing users of lib/neutron-legacy should remain unharmed.
