I doubt FlowVisor speaks Open vSwitch's configuration protocol, but that would
be a question better suited to the FlowVisor mailing list:
http://mailman.stanford.edu/mailman/listinfo/flowvisor-users
If you just want to make those changes remotely, you can use ovs-vsctl over
TCP/SSL. You'll just need to tell ovsdb-server to listen with the appropriate
method. For example:
ovs-vsctl set-manager ptcp:6634
Then, when you want to remotely configure OVS, tell ovs-vsctl to use that
connection method. Something like:
ovs-vsctl --db tcp:<ip_of_ovs>:6634 set port eth0 qos <blah,blah,blah>
I didn't test those commands, so they may be slightly off, but it should point
you in the right direction.
