-Testing SR-IOV
-==============
-
-NFVbench supports SR-IOV with the PVP and PVVP packet flow. Most use cases for SR-IOV only require single VNF chains (NxPVP).
-Daisy chaining VNFs with SR-IOV (PVVP) requires selecting either SR-IOV for the middle network or a fast vswitch (using the
-standard OVS for that purpose works but would be a serious bottleneck)
-
-Instructions below refer to the PVP or PVVP use cases.
-For external chains using SR-IOV, select the VLAN tagging option that corresponds to the external chains SR-IOV setting.
-
-Pre-requisites
---------------
-To test SR-IOV you need to have compute nodes configured to support one or more SR-IOV interfaces (also knows as PF or physical function)
-and you need OpenStack to be configured to support SR-IOV.
-You will also need to know:
-- the name of the physical networks associated to the SR-IOV interfaces (this is a configuration in Nova compute)
-- the VLAN range that can be used on the switch ports that are wired to the SR-IOV ports. Such switch ports are normally configured in trunk mode with a range of VLAN ids enabled on that port
-
-For example, in the case of 2 SR-IOV ports per compute node, 2 physical networks are generally configured in OpenStack with a distinct name.
-The VLAN range to use is is also allocated and reserved by the network administrator and in coordination with the corresponding top of rack switch port configuration.
-
-
-Configuration
--------------
-To enable SR-IOV test, you will need to provide the following configuration options to NFVbench (in the configuration file).
-This example instructs NFVbench to create the left and right networks of a PVP packet flow to run on 2 SRIOV ports named "phys_sriov0" and "phys_sriov1" using resp. segmentation_id 2000 and 2001:
-
-.. code-block:: bash
-
- sriov: true
- internal_networks:
- left:
- segmentation_id: 2000
- physical_network: phys_sriov0
- right:
- segmentation_id: 2001
- physical_network: phys_sriov1
-
-The segmentation ID fields must be different.
-In the case of PVVP, the middle network also needs to be provisioned properly.
-The same physical network can also be shared by the virtual networks but with different segmentation IDs.
-
-Multi-Chaining
---------------
-The above configuration works for multi-chaining and shared network ("service_chain_shared_net" set to true).
-In that case all VNFs will share the same left and right network/VLAN.
-
-In the case of non shared network ("service_chain_shared_net" set to false), the segmentation_id fields must
-contain a list of distinct VLANs to use for each chain. Example of configuration for 3 chains:
-
-.. code-block:: bash
-
- sriov: true
- internal_networks:
- left:
- segmentation_id: [2000, 2001, 2002]
- physical_network: phys_sriov0
- right:
- segmentation_id: [2100, 2101, 2102]
- physical_network: phys_sriov1
-
-Alternatively it is also possible to specify different physnets per chain:
-
-.. code-block:: bash
-
- sriov: true
- internal_networks:
- left:
- segmentation_id: [2000, 2001, 2002]
- physical_network: [phys_sriov0, phys_sriov2, phys_sriov4]
- right:
- segmentation_id: [2100, 2101, 2102]
- physical_network: [phys_sriov1, phys_srviov3, phys_sriov5]
-
-
-NFVbench cores with SR-IOV
---------------------------
-The default core count for NFVbench/TRex may not be sufficient for higher throughput line cards (greater than 10Gbps).
-This will result in warning messages such as:
-
-.. code-block:: bash
-
- INFO WARNING: There is a significant difference between requested TX rate (119047618) and actual TX rate (38897379).
- The traffic generator may not have sufficient CPU to achieve the requested TX rate.
-
-In that case it is recommended to try allocating more cores to TRex using the cores property in the configuration
-file, for example to set to 8 cores:
-
-.. code-block:: bash
-
- cores: 8
-
-It is also advisable to increase the number of vcpus in the VMs:
-
-
-VM Flavor for SR-IOV and NIC NUMA socket placement
---------------------------------------------------
-
-Because SR-IOV throughput uses a lot of CPU in the VM, it is recommended to increase the
-vcpu count, for example to 4 vcpus:
-
-.. code-block:: bash
-
- flavor:
- # Number of vCPUs for the flavor
- vcpus: 4
- # Memory for the flavor in MB
- ram: 8192
- # Size of local disk in GB
- disk: 0
- extra_specs:
- "hw:cpu_policy": dedicated
-
-If the 2 selected ports reside on NICs that are on different NUMA sockets, you will need to explicitly tell Nova to use 2 numa nodes in the flavor used for the VMs in order to satisfy the filters, for example:
-
-.. code-block:: bash
-
- flavor:
- # Number of vCPUs for the flavor
- vcpus: 4
- # Memory for the flavor in MB
- ram: 8192
- # Size of local disk in GB
- disk: 0
- extra_specs:
- "hw:cpu_policy": dedicated
- "hw:numa_nodes": 2
-
-Failure to do so might cause the VM creation to fail with the Nova error
-"Instance creation error: Insufficient compute resources:
-Requested instance NUMA topology together with requested PCI devices cannot fit the given host NUMA topology."
-
-Example of configuration file (shared network)
-----------------------------------------------
-
-Single chain or multi-chain with shared network (only requires 2 segmentation ID for all chains):
-
-.. code-block:: bash
-
- flavor:
- # Number of vCPUs for the flavor
- vcpus: 4
- # Memory for the flavor in MB
- ram: 8192
- # Size of local disk in GB
- disk: 0
- extra_specs:
- "hw:cpu_policy": dedicated
- cores: 8
- sriov: true
- internal_networks:
- left:
- segmentation_id: 3830
- physical_network: phys_sriov0
- right:
- segmentation_id: 3831
- physical_network: phys_sriov1
-
-Example of full run 2xPVP shared network SR-IOV:
