Improving online and offline flow debugging with ofparse and ovs-offline

Speakers: Adrián Moreno (Red Hat, Inc.), Salvatore Daniele (Red Hat, Inc.) Troubleshooting OpenvSwitch and OVN issues is a path full of thorns. It typically involves staring deeply at a huge dump of flows (openflow or datapath) while trying to get context of what OVN logical entity created them. Apart from the eye strain that is inevitably associated with this task, it's sometimes difficult to extract the datapath logic out of the plain list of flows. This becomes even more difficult when you don't have access to the live system and you only have a set of logs because you cannot make use of our beloved ovs/ovn utilities. We have tried to make this troubleshooting tasks a bit less painful by creating a set of tools that facilitate the visualization of openflow and datapath flows without leaving your console as well as automate the creation of an offline debugging environment that mimics the real one. In this talk, we'd like to present these new tools and demo them to the community. Apart from helping everyone debug OVS and OVN issues we hope to get feedback from the community that can inspire our next steps in this effort to improve OVS and OVN debuggability.
