Description RHOS Integration 2014-02-14 05:07:56 UTC
Cloned from launchpad blueprint


Add  ML2 MechanismDriver for SR-IOV capable NIC based switching (HW VEB), such as Mellanox ConnectX Family .
This will initially support VLAN  networking type.
The ML2 Mechanism driver will require L2 Agent in order to manage and update networking settings.

This blueprint is based and subject to nova and neutron enhancements  to support SR-IOV ports added during the Icehouse release:

Updating based on BP milestone

Comment 2 Nir Yechiel 2014-03-06 14:30:00 UTC
Updating based on upstream milestone

Comment 3 Nir Yechiel 2014-07-15 12:50:10 UTC
Spec is approved. Currently on track for J2.

ML2 mechanism driver (sriovnicswitch)

- Initially support only VLAN as network type
- Port binding is handled by VIF Driver via libvirt domain XML
- PCI vendor initially matching Mellanox ConnectX. If other NICs are used (e.g., Intel) there is a need to update 'supported_vendor_pci_devs' in ml2_conf_sriov.ini to include the card vendor

L2 agent (SriovNicSwitch L2 agent)

The agent is part of the spec, but is only required for port updates (e.g., if the pNIC supports virtual function admin state settings). For NIC that does not support dynamic updates, no need to deploy the agent, hence the 'agent_required' flag in ml2_conf_sriov.ini
