Re-targeting to 2.7 since this is not a blocker. https://github.com/kubevirt/kubevirt/pull/5381 Fixes it, But the report would be still be flaky due to https://bugzilla.redhat.com/show_bug.cgi?id=1907707 Which will be handled on following PRs. Test Case 1: Change ipv4 address for sriov1 nic and make sure vmi status reflect the right status.
==================================================================================================
Before test :
$ oc get vmi sriov-vm1-1619605206-7889736 -n sriov-test-sriov -o yaml
guestOSInfo:
.....
- interfaceName: sriov1
ipAddress: 10.200.1.1
ipAddresses:
- 10.200.1.4
- 2620:52:0:2e29:0:b5ff:feb5:b501
- fe80::b5ff:feb5:b501
mac: 02:00:b5:b5:b5:01
name: sriov-test-network
Login into the vm : virtctl console sriov-vm1-1619605206-7889736 -n sriov-test-sriov
Change the ip of the nic: sudo ifconfig sriov1 10.200.1.4
Check vmi again after sometime:
guestOSInfo:
...
- interfaceName: sriov1
ipAddress: 10.200.1.4
ipAddresses:
- 10.200.1.4
- 2620:52:0:2e29:0:b5ff:feb5:b501
- fe80::b5ff:feb5:b501
mac: 02:00:b5:b5:b5:01
name: sriov-test-network
Test Case 2: Apply same changes for ipv6
========================================
Before test :
- interfaceName: sriov1
ipAddress: 10.200.1.4
ipAddresses:
- 10.200.1.4
- 2620:52:0:2e29:0:b5ff:feb5:b501
- fe80::b5ff:feb5:b501
mac: 02:00:b5:b5:b5:01
Apply changes: sudo ifconfig sriov1 inet6 add 2001:0db8:0:f101::1/64
After changes :
- interfaceName: sriov1
ipAddress: 10.200.1.4
ipAddresses:
- 10.200.1.4
- 2001:db8:0:f101::1
- 2620:52:0:2e29:0:b5ff:feb5:b501
- fe80::b5ff:feb5:b501

Run the vm and try to change the ip in it. 2. 3. Actual results: VMI status is not getting updated for SR-IOV nic's.
