HI,

is sr-iov support from nova/neutron with ml2 plugin available in iCEHOUSE release? Also i want to know the limitations of sr-iov feature using openstack. VMWare is having limitation within Virtual machine using SR-IOV. See the below

Basic PCI Passthrough support was added in Havana but has not improved significantly in Icehouse. The support that is there allows basic passthrough of a device, including a virtual function on an SR-IOV capable card, by its PCI ID. More information on doing this is available here:

The problem with the current approach is that neither Nova nor Neutron have any real insight into the capabilities of the device or what network it is attached to. Improving upon this is set to be discussed at the OpenStack Juno Design Summit in Atlanta coming up in May. Some of the draft design work is available here:
