When running {VirtProductName} on {ibm-z-name}, be aware that certain network interfaces such as OSA, RoCE, and HiperSockets only forward network traffic to devices that are registered with the respective interface. As a result, any traffic destined for unregistered devices is not forwarded. For more information, see link:https://www.ibm.com/docs/en/linux-on-systems?topic=choices-osa-interface-traffic-forwarding[OSA interface traffic forwarding] (IBM documentation).
