Developed and integrated end-to-end virtual machine networking validation for KubeVirt within the openshift/origin repository, focusing on ensuring preconfigured IP and MAC address persistence across VM restarts and live migrations. Leveraged Go and YAML to implement targeted tests that verify address retention and detect collisions when duplicate addresses are requested, supporting reliable networking in Kubernetes-based virtualization environments. The work addressed operational risks by validating that VMs maintain predictable network identities, which is critical for safe migrations and stable deployments. Emphasis was placed on Kubernetes testing methodologies and networking principles to enhance the robustness of VM lifecycle management in production scenarios.
