What made you think that either form above should work?  I would like to
correct it.

The FAQ says:

   If your controllers are not actually in-band (e.g. they are on
   localhost via, or on a separate network), then you should
   configure your controllers in "out-of-band" mode.  If you have one
   controller on bridge br0, then you can configure out-of-band mode
   on it with:

       ovs-vsctl set controller br0 connection-mode=out-of-band
