Nova Plugin for OpenContrail
|
|
==========================================
|
|
|
|
https://blueprints.launchpad.net/nova/+spec/opencontrail-nova-vif-driver-plugin
|
|
|
|
This blueprint is to add plugin for OpenContrail in existing Nova
|
|
VIF driver to support OpenContrail based network virtualization
|
|
for Openstack.
|
|
|
|
The OpenContrail APIs will cover following:
|
|
|
|
* Create Interface
|
|
* Delete Interface
|
|
* Get Interface Config
|
|
|
|
|
|
Problem description
|
|
===================
|
|
|
|
OpenContrail is open source network virtualization solution. It uses standards
|
|
based BGP L3VPN closed user groups to implement virtual networks.
|
|
The link http://OpenContrail.org/OpenContrail-architecture-documentation/
|
|
explains the architecture of OpenContrail plugin
|
|
OpenContrail plugin get merged to neutron on Juno timeframe.
|
|
|
|
OpenContrail is loading its VIF driver via openstack-config command
|
|
using option libvirt_vif_driver. In Juno this option is no longer supported
|
|
and same needs to be implemented under Nova VIF driver.
|
|
|
|
Use Cases
|
|
---------
|
|
|
|
Use Nova with Neutron + OpenContrail
|

|
|
Following APIs will be implemented:
|
|
|
|
def get_config_vrouter(self, instance, vif, image_meta, inst_type, virt_type)
|
|
|
|
def plug_vrouter(self, instance, vif)
|
