Ethernet Configuration with Mellanox

SR-IOV Networking in OpenStack Kilo

OpenStack Juno added inbox support to request VM access to virtual network via SR-IOV NIC. With the introduction of SR-IOV based NICs, the traditional virtual bridge is no longer required. Each SR-IOV port is associated with a virtual function (VF). SR-IOV ports may be provided by Hardware-based Virtual Ethernet Bridging (HW VEB); or they may be extended to an upstream physical switch (IEEE 802.1br). There are two ways that SR-IOV port may be connected:

  • directly connected to its VF
  • connected with a macvtap device that resides on the host, which is then connected to the corresponding VF

Ceilometer

The Mellanox Ceilometer SR-IOV module allows the OpenStack Ceilometer to collect measurements of SR-IOV counters.
