Description of problem:

This is on an OCP 4.6 baremetal cluster of 3 master and 2 worker nodes, installed with IPI Ansible method ( see steps below) with OVNKubernetes network plugin, and openshift-network-sriov-operator successfully deployed.


The Topology Manager OpenShift E2E test "[Serial][sig-node][Feature:TopologyManager] Configured cluster with gu workload attached to SRIOV networks should let resource-aligned PODs have working SRIOV network interface [Suite:openshift/conformance/serial]" fails with following error on OCp 4.6 baremetal cluster with OVNKubernetes network plugin, and openshift-network-sriov-operator successfully deployed:

Version-Release number of selected component (if applicable):

Client Version: 4.6.0-0.nightly-2020-10-03-051134
Server Version: 4.6.0-0.nightly-2020-10-03-051134
Kubernetes Version: v1.19.0+db1fc96

How reproducible:
Everytime

Steps to Reproduce:
1. Install OCP 4.6.0-0.nightly-2020-10-03-051134 nightly clusters (3 masters and two worker nodes) with Jetski IPI Ansible automation on baremetal cluster (see steps in https://github.com/redhat-performance/JetSki)

2. Configure CPU manager with static policy and Enable Topology manager ( see docs: 
https://docs.openshift.com/container-platform/4.5/scalability_and_performance/using-cpu-manager.html
https://docs.openshift.com/container-platform/4.5/scalability_and_performance/using-topology-manager.html

3.  Deploy SR-IOV network operator:
git clone https://github.com/openshift/sriov-network-operator.git
make deploy-setup

4. Label worker with Mellanox SR-IOV cards with virtualization enabled in bios:
oc label node worker000 feature.node.kubernetes.io/sriov-capable=true

5. oc create -f sriov-policy.yaml:
apiVersion: sriovnetwork.openshift.io/v1
kind: SriovNetworkNodePolicy
metadata:
 name: policy-sriov
 namespace: openshift-sriov-network-operator
spec:
 resourceName: intelsriov
 nodeSelector:
   feature.node.kubernetes.io/sriov-capable: 'true'
 priority: 51
 mtu: 1500
 numVfs: 8
 nicSelector:
   vendor: '8086'
   rootDevices:
     - '0000:86:00.1'
   pfNames:
     - ens7f1
 deviceType: netdevice

6. oc create -f sriov-ipam.yaml:
apiVersion: sriovnetwork.openshift.io/v1
kind: SriovNetwork
metadata:
 name: sriov-intel
 namespace: openshift-sriov-network-operator
spec:
 ipam: |
   {
     "type": "host-local",
     "subnet": "10.56.217.0/24",
     "rangeStart": "10.56.217.171",
     "rangeEnd": "10.56.217.181",
     "routes": [{
       "dst": "0.0.0.0/0"
     }],
     "gateway": "10.56.217.1"
   }
 vlan: 0
 resourceName: intelsriov
 networkNamespace: default

7. git clone openshift origin in $GOPATH/src/github.com/openshift/
  https://github.com/openshift/origin.git
  cd $GOPATH/src/github.com/openshift/
  make WHAT=cmd/openshift-tests

8. Export env vars and run topology manager E2E tests:
  export KUBECONFIG=/root/.kube/config
  export SRIOV_NETWORK_NAMESPACE=default
  export SRIOV_NETWORK=sriov-intel
  export RESOURCE_NAME=openshift.io/intelsriov
  OPENSHIFT_TESTS=/root/go/src/github.com/openshift/origin/openshift-tests

9. Run topology manager E2E tests
  $OPENSHIFT_TESTS run openshift/conformance --dry-run | grep -E "TopologyManager" | $OPENSHIFT_TESTS run -f -

Actual results:
Pass fails with permission issues trying to ping between pods
failed: (1m32s) 2020-10-10T20:20:49 "[Serial][sig-node][Feature:TopologyManager] Configured cluster with gu workload attached to SRIOV networks should let resource-aligned PODs have working SRIOV network interface [Suite:openshift/conformance/serial]"

Expected results:
pass test
