Description of problem:
As seen in this run, the following test fails:
[sig-kubevirt] migration when running openshift cluster on KubeVirt virtual machines and live migrate hosted control plane workers [Early] should maintain node readiness [Suite:openshift/conformance/parallel]
Version-Release number of selected component (if applicable):
4.19, Cilium 1.15.1
How reproducible:
Often but not always
Steps to Reproduce:
1. Run Conformance tests against a hosted cluster that is started via Kubevirt and using Cilium CNI (setup can be found in this job: https://github.com/openshift/release/pull/63263
Actual results:
The test sometimes fails and breaks also other monitoring tests that monitor node readiness during the run of the whole test suite.

Expected results:
Nodes is ready all the time and doesn't loose readiness
