Nova Plugin for OpenContrail¶
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:
Get Interface Config
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 Nova with Neutron + OpenContrail For more details, please take a look this link http://www.opencontrail.org/opencontrail-architecture-documentation/#section1_1
Add OpenContrail APIs to handle the Creation/Deletion/Get of interfaces in Nova VIF driver. There are no changes to the Nova common code.
Data model impact¶
REST API impact¶
None. There are no new API added to Nova. For above listed API all features will be supported by the plugin.
The communication channel to the backend is not secure. We will support secure channel in the future.
Other end user impact¶
Other deployer impact¶
Other Developers wont be effected by this change.
Model - VIF_TYPE_VROUTER
Following APIs will be implemented:
def get_config_vrouter(self, instance, vif, image_meta, inst_type, virt_type)
def plug_vrouter(self, instance, vif)
def unplug_vrouter(self, instance, vif)

OpenContrail API implementation
OpenContrail mocks for unit-tests
Existing and new Nova unit tests will be used.
Existing and new tempest testing for Nova will be used.
