Hi Scott, That means that you got 2 ipv4 packets on the interface without an IP address If you want to see what happens exactly you can execute: trace filter include ip4-not-enabled 10 trace add virtio-input 10 and then see the trace. It will show on what interface without an IP you're getting those packets.
