The DevStack plugin for Neutron has a way to build a specific OVS version from source https://github.com/openstack/neutron/blob/master/devstack/lib/ovs However there is not a lot of documentation for how it can be used (which really should be fixed). I believe it would be something like this in your local.conf: enable_plugin neutron https://git.openstack.org/openstack/neutron OVS_BRANCH="v2.6.0" I haven't tried it locally, but I think that's the idea. -- Sean M.
