Hi Ben,

I can try to help with setting up ovn-heater, in theory it should be
enough to export OVS_REPO, OVS_BRANCH, OVN_REPO, OVN_BRANCH, make them
point to your repos and branches and then run "do.sh install" and it
should take care of installing all the dependencies and repos.

I can also try to run the scale tests on our downstream if that helps.
