      • No UXD
      • D/S documentation explicitly mentioning that this is supported and describing how to create a VM on such cluster
      • D/S test automation
      • U/S test automation with IPv6 single-stack lane
      • KubeVirt's control plane is able to run without any IPv4 addressing
      • It is possible to create a VMs able to communicate over primary UDN
      • This VM supports live migration
      • The default VM created through the UI supports this out of the box, i.e. it needs to be able to obtain the required IP address

      Goal

      IPv6 single-stack for the control and data planes

      User Stories

      • As a telco admin that is trying to move away from IPv4, I want to be able to use only IPv6 in my OCP cluster.

      Non-goals

      • Service Mesh does not need to be covered
      • Dynamic IP configuration of the VM is not a must - user can be requested to set the IP themselves, e.g. using cloud init
      • Pod network and layer2 overlay support is not required at this point
