[release-4.20] CORENET-6378: back-port IP & MAC conflict detection e2e tests #30414
Conversation
Validates that KubeVirt VMs with preconfigured MAC and IP addresses maintain those addresses correctly before and after a vmi with duplicate IP/MAC request is made, and that the vmi with the duplicate address get the appropriate address conflict error event.

The requested IPs for the primary UDN attachment are not in the VMI spec, but in an annotation in the VMI. Hence, we need to fetch that particular annotation, and set it in the duplicate VMI. This was implemented using the builder pattern, since I suspect in the future we will need to further customize the VMI spec / metadata; this will make it simpler to extend the framework in the future.

This way we can ensure appropriate cases are caught in a generic way. With it, we can safely expect to find IP conflicts when there are duplicate IPs in the network. In future commits, we will be able to catch MAC conflicts when there are duplicate MACs in the network Co-authored-by: Ram Lavi <[email protected]> Signed-off-by: Miguel Duarte Barroso <[email protected]> (cherry picked from commit fdb0584)
Verify KubeVirt VMs with preconfigured MAC address retain a requested MAC address before and after another VM is created requesting the same MAC address. And verify the other VM requesting the same MAC address get the appropriate address conflict error event. Signed-off-by: Or Mergi <[email protected]> (cherry picked from commit 0c58f2a)
