8.2. 启用 OVS 硬件卸载

流程

1. 为集群中的两个 hw-offload 类型 VF 接口创建一个 SriovNetworkNodePolicy 策略：

   第一个虚拟功能接口

   apiVersion: sriovnetwork.openshift.io/v1
   kind: SriovNetworkNodePolicy 1
   metadata:
     name: "hwoffload9"
     namespace: openshift-sriov-network-operator
   spec:
     deviceType: netdevice
     isRdma: true
     nicSelector:
       pfNames: 2
       - ens6
     nodeSelector:
       feature.node.kubernetes.io/network-sriov.capable: 'true'
     numVfs: 1
     priority: 99
     resourceName: "hwoffload9"

   1

   在此处插入 SriovNetworkNodePolicy 值。

   2

   两个接口都必须包含物理功能(PF)名称。

   第二个虚拟功能接口

   apiVersion: sriovnetwork.openshift.io/v1
   kind: SriovNetworkNodePolicy 1
   metadata:
     name: "hwoffload10"
     namespace: openshift-sriov-network-operator
   spec:
     deviceType: netdevice
     isRdma: true
     nicSelector:
       pfNames: 2
       - ens5
     nodeSelector:
       feature.node.kubernetes.io/network-sriov.capable: 'true'
     numVfs: 1
     priority: 99
     resourceName: "hwoffload10"

   1

   在此处插入 SriovNetworkNodePolicy 值。

   2

   两个接口都必须包含物理功能(PF)名称。

2. 为两个接口创建 NetworkAttachmentDefinition 资源：

   第一接口的 NetworkAttachmentDefinition 资源

   apiVersion: k8s.cni.cncf.io/v1
   kind: NetworkAttachmentDefinition
   metadata:
     annotations:
       k8s.v1.cni.cncf.io/resourceName: openshift.io/hwoffload9
     name: hwoffload9
     namespace: default
   spec:
       config: '{ "cniVersion":"0.3.1", "name":"hwoffload9","type":"host-device","device":"ens6"
       }'

   第二个接口的 NetworkAttachmentDefinition 资源

   apiVersion: k8s.cni.cncf.io/v1
   kind: NetworkAttachmentDefinition
   metadata:
     annotations:
       k8s.v1.cni.cncf.io/resourceName: openshift.io/hwoffload10
     name: hwoffload10
     namespace: default
   spec:
       config: '{ "cniVersion":"0.3.1", "name":"hwoffload10","type":"host-device","device":"ens5"
       }'

3. 使用通过 pod 创建的接口。例如：

   使用两个 OVS 卸载接口的 Pod

   apiVersion: v1
   kind: Pod
   metadata:
     name: dpdk-testpmd
     namespace: default
     annotations:
       irq-load-balancing.crio.io: disable
       cpu-quota.crio.io: disable
       k8s.v1.cni.cncf.io/resourceName: openshift.io/hwoffload9
       k8s.v1.cni.cncf.io/resourceName: openshift.io/hwoffload10
   spec:
     restartPolicy: Never
     containers:
     - name: dpdk-testpmd
       image: quay.io/krister/centos8_nfv-container-dpdk-testpmd:latest
