You'll now need to manipulate the configuration using a tool (ovs-vsctl)
rather than directly by hand.  Everything that you could do before with the
config file is exposed through this tool, so the basic usage hasn't changed
too much.  You won't need to HUP ovs-vswitch after changes, as it will
automatically reload.

ovs-vsctl actually existed in earlier releases but it was mostly used by
scripts.  It has been significantly expanded for the next release though.
