## Motivation See lessons learned meeting #139136. We would again benefit from an easier reproducer. Related to #135818 . Come up with a way to ping over GRE tunnels and TAP devices and openvswitch outside a VM SUT with differing packet sizes. ## Acceptance criteria * **AC1:** We know how to ping over GRE tunnels and TAP devices and openvswitch outside a VM SUT with differing packet sizes ## Suggestions * Research upstream about pinging over specific interfaces, GRE tunnels, TAP devices, openvswitch, etc. * Like `ping -I<interface>` or `ping X.X.X.X%tap0`? * Checkout network namespaces and if they could be used * Research about MTU size debugging, tracepath, traceroute, etc. * Experiment in an openQA-environment or openQA-like with the bridges, tap devices, etc. * Demonstrate to the team in written form or interactively * Lookup how the existing check is done via a VM/VNC, and see how this could be simplified
