Chapter 3. Configure SR-IOV Support for Virtual Networking

This chapter covers the configuration of Single Root Input/Output Virtualization (SR-IOV) within the Red Hat OpenStack Platform 10 environment using the director.

Note

This guide provides examples for CPU assignments, memory allocation, and NIC configurations that may vary from your topology and use case. See the Network Functions Virtualization Product Guide and the Network Functions Virtualization Planning Guide to understand the hardware and configuration options.

Note

Do not edit or change isolated_cores or other values in etc/tuned/cpu-partitioning-variables.conf that are modified by these director heat templates.

In the following procedure, you need to update the network-environment.yaml file to include parameters for kernel arguments, SR-IOV driver, PCI passthrough and so on. You must also update the compute.yaml file to include the SR-IOV interface parameters, and run the overcloud_deploy.sh script to deploy the overcloud with the SR-IOV parameters.

3.1. Configure Two-port SR-IOV with VLAN Tunnelling
复制链接

This section describes the YAML files you need to modify to configure SR-IOV with two ports that use VLAN tunnelling for your OpenStack environment.

Note

If you have included the following lines in the first-boot.yaml file in a previous deployment, remove these lines for Red Hat OpenStack Platform 10 with Open vSwitch 2.9.

Under parameter_defaults, set the SR-IOV configuration parameters.
1. Enable the SR-IOV mechanism driver (sriovnicswitch).
  NeutronMechanismDrivers: "openvswitch,sriovnicswitch"

2. Configure the Compute pci_passthrough_whitelist parameter, and set devname for the SR-IOV interface. The whitelist sets the PCI devices available to instances.
  NovaPCIPassthrough: - devname: "p7p1" physical_network: "tenant" - devname: "p7p2" physical_network: "tenant"

3. Specify the physical network and SR-IOV interface in the format - PHYSICAL_NETWORK:PHYSICAL DEVICE.
  All physical networks listed in the network_vlan_ranges on the server should have mappings to the appropriate interfaces on each agent.
  NeutronPhysicalDevMappings: "tenant:p7p1,tenant:p7p2"

4. Provide the number of Virtual Functions (VFs) to be reserved for each SR-IOV interface.
  Red Hat OpenStack Platform supports the number of VFs supported by the NIC vendor. See Deployment Limits for Red Hat OpenStack Platform for other related details. This example reserves 5 VFs for each of the SR-IOV interfaces:
  NeutronSriovNumVFs: "p7p1:5,p7p2:5"

  Note
  Changing the NeutronSriovNumVFs parameter within a running environment is known to cause a permanent outage for all running instances which have an SR-IOV port on that PF. Unless you hard reboot these instances, the SR-IOV PCI device will not be visible to the instance.
Under parameter_defaults, reserve the RAM for the host processes.

You need to add hw:mem_page_size=1GB to the flavor you associate with the DPDK instance. If you do not do this, the instance does not get a DHCP allocation.

3.1.5. Run the overcloud_deploy.sh Script

The following example defines the openstack overcloud deploy command for the VLAN environment.

openstack overcloud deploy \
--templates \
-e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/neutron-sriov.yaml \
-e /home/stack/ospd-10-vlan-sriov-two-ports-ctlplane-bonding/network-environment.yaml \
--log-file overcloud_install.log &> overcloud_install.log

openstack overcloud deploy \
--templates \
-e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml \
-e /usr/share/openstack-tripleo-heat-templates/environments/neutron-sriov.yaml \

/usr/share/openstack-tripleo-heat-templates/environments/neutron-sriov.yaml is the location of the default neutron-sriov.yaml file, which enables the SR-IOV parameters in the Compute node.
/home/stack/<relative-directory>/network-environment.yaml is the path for the network-environment.yaml file. The default neutron-sriov.yaml values can be overridden in network-environment.yaml file.

3.2. Create a Flavor and Deploy an Instance for SR-IOV
复制链接

After you have completed configuring SR-IOV for your Red Hat OpenStack Platform deployment with NFV, you need to create a flavor and deploy an instance by performing the following steps.

Create an aggregate group and add a host to it for SR-IOV. Define metadata, for example, "aggregate_instance_extra_specs:sriov"="true", that matches flavor metadata.

openstack aggregate create sriov_group

 # openstack aggregate create sriov_group
 # openstack aggregate set --property \
 "aggregate_instance_extra_specs:sriov"="true" sriov_group
 # openstack aggregate add host sriov compute-sriov-0.localdomain

Create a flavor.

openstack flavor create <flavor> --ram <MB> --disk <GB> --vcpus <#>

# openstack flavor create <flavor> --ram <MB> --disk <GB> --vcpus <#>

Set additional flavor properties. Note that the defined metadata, "aggregate_instance_extra_specs:sriov"="true", matches the defined metadata on the SR-IOV aggregate.

openstack flavor set --property "aggregate_instance_extra_specs:sriov"="true" \
--property hw:cpu_policy=dedicated \
--property hw:mem_page_size=large <flavor>

# openstack flavor set --property "aggregate_instance_extra_specs:sriov"="true" \
--property hw:cpu_policy=dedicated \
--property hw:mem_page_size=large <flavor>

Create the network.

openstack network create net1 --provider-physical-network tenant --provider-network-type vlan --provider-segment <VLAN-ID>

# openstack network create net1 --provider-physical-network tenant --provider-network-type vlan --provider-segment <VLAN-ID>

Create the subnet.

openstack subnet create subnet1 --network net1 --subnet-range 192.0.2.0/24 --dhcp

# openstack subnet create subnet1 --network net1 --subnet-range 192.0.2.0/24 --dhcp

Create the port.

Use vnic-type direct to create an SR-IOV VF port.

openstack port create --network net1 --vnic-type direct sriov_port

# openstack port create --network net1 --vnic-type direct sriov_port

Use vnic-type direct-physical to create an SR-IOV PF port.

openstack port create --network net1 --vnic-type direct-physical sriov_port

# openstack port create --network net1 --vnic-type direct-physical sriov_port

Deploy an instance.

openstack server create --flavor <flavor>  --image <glance_image> --nic port-id=sriov_port <name>

# openstack server create --flavor <flavor>  --image <glance_image> --nic port-id=sriov_port <name>
