ONAP SR-IOV NIC design

Overall design

Capability Name	Capability Value	Descriptiopn
pciVendorId		PCI-SIG vendor ID for the device
pciDeviceId		PCI-SIG device ID for the device
pciNumDevices		Number of PCI devices required.
pciAddress		Geographic location of the PCI device via the standard PCI-SIG addressing model of Domain:Bus:device:function
pciDeviceLocalToNumaNode	required notRequired	Determines if I/O device affinity is required.

Capability Name	Capability Value	Description
nicFeature	LSO, LRO, RSS, RDMA	Long list of NIC related items such as LSO, LRO, RSS, RDMA, etc.
dataProcessingAccelerationLibray	Dpdk_Version	Name and version of the data processing acceleration library required. Orchestration can match any NIC that is known to be compatible with the specified library.
interfaceType	Virtio, PCI-Passthrough, SR-IOV, E1000, RTL8139, PCNET	Network interface type
vendorSpecificNicFeature	TBA	List of vendor specific NIC related items.

After Openstack configs SR-IOV NIC, we will have a provider network.

$ openstack network create --privider-network-type vlan --provider-physical-network physnet tenant_net

$ openstack subnet create --network tenant_net --subnet-range 192.168.100.0/24 subnet

2. Get the id of the neutron network where you want the SR-IOV port to be created:

$ net_id=`neutron net-show tenant_net | grep "\ id\ " | awk '{ print $4 }'`

3. Create the SR-IOV port. We specify vnic_type=direct, but other options include normal, direct-physical, and macvtap:

$ port_id=`neutron port-create $net_id --name sriov_port --binding:vnic_type direct | grep "\ id\ " | awk '{ print $4 }'`

4. Create the VM. For the nic we specify the SR-IOV port created in step 2:

$ nova boot --flavor m1.large --image ubuntu_14.04 --nic port-id=$port_id test-sriov

Note: VF-C will execute four steps call four times to multi-cloud. SO will execute four steps just call one times to multi-cloud.
