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 For more details, please take a look this link http://www.opencontrail.org/opencontrail-architecture-documentation/#section1_1
