[ovs-discuss] Request: Debugging/troubleshooting OVN+Docker

[Scott Lowe]

Hi all, I was wondering if someone here could help me debug/troubleshoot an OVN+Docker environment that I've built for a demo in late October. I have three Ubuntu 14.04 nodes running Docker 1.11.2 and OVN 2.6 (built from source, including the kernel module). I've followed the instructions from INSTALL.Docker.md, and everything *seems* to work. However, I have no connectivity between two Docker containers attached to the same Docker network and running on two different hosts.

Where should I start to help figure out why connectivity isn't working? I see the logical switch in OVN (using `ovn-nbctl ls-list`), the logical ports (using `ovn-nbctl lsp-list`), and see the correct addresses on those ports (using `ovn-nbctl lsp-get-addresses`). What I *don't* see is any tunnel ports in `ovs-vsctl show`. I've verified the STT and Geneve kernel modules are loaded.

Any suggestions on what else to check?
