I think<br class="">that it's OK if we override the default at the gate to run OVS, since<br class="">that has the most test coverage and will cause the least disruption.<br class="">There will be jobs created, that will test Linux Bridge similar to how<br class="">Open vSwitch is tested at the gate today.<br class=""><br class="">As a DevStack user, I would like to see Neutron as the default. After<br class="">making Neutron the default, the changes needed for the local.conf file<br class="">for me to run my mechanism driver of choice is significantly smaller<br class="">than the changes needed today for my local.conf/localrc to<br class="">disable Nova-Network, enable Neutron, and run my mechanism driver of choice.<br class=""><br class="">If Linux Bridge being the default is the way to make the above happen,<br class="">so be it.<br class=""><br class=""></blockquote><div class="">++, well said Sean.
