Description of problem:
creating a vm with sriov secondary interface, the interface is sometimes shown
for a few minutes and then gone for a few minutes.

Version-Release number of selected component (if applicable):
OCP 4.6.1
CNV 2.6.0

How reproducible:
Always

Steps to Reproduce:
1. install sriov operator

2. label sriov capable worker nodes with 'feature.node.kubernetes.io/network-sriov.capable: "true"'
(you can find them by using 'oc get sriovnetworknodestate'

3.apply attached configurations (name of pfNames in the policy needs to fit the suitable sriov nics on the nodes)

Actual results:
sometimes you see and sometimes you dont see the secondary interface in the vmi yaml

Expected results:
always see all interfaces

PR that should fix it https://github.com/kubevirt/kubevirt/pull/5560

Comment 4 Petr Horáček 2021-05-18 07:20:23 UTC
Moving back to POST, MODIFIED means that the code got merged on the relevant release (4.8).

Comment 5 Ofir Nash 2021-05-27 16:17:18 UTC
Verified. Scenario checked:

1. Labeled sriov worker nodes:
[cnv-qe-jenkins@cnvqe-08 ofir]$ oc get sriovnetworknodestate -A
NAMESPACE                          NAME                               AGE
openshift-sriov-network-operator   cnvqe-10.lab.eng.tlv2.redhat.com   72d
openshift-sriov-network-operator   cnvqe-11.lab.eng.tlv2.redhat.com   72d

oc label node cnvqe-10/11.lab.eng.tlv2.redhat.com feature.node.kubernetes.io/network-sriov.capable=true


2. Applied the three configuration that were attached: SriovNetworkNodePolicy, SriovNetwork and VirtualMachineInstance
(In the last configuration (VirtualMachineInstance), need to add namespace attribute as it is missing: "namespace: openshift-sriov-network-operator").
oc apply -f <ConfigurationsNames.yaml>

3. Verified secondary interface shows up in the vmi yaml created:
oc get vmi -n openshift-sriov-network-operator vmi-sriov -o yaml
