Does Controller which Flowvisor connected need to install some rule on ovs?

[KerKerRed]

Hi all,

I'm testing a easy experiment of FlowVisor.

Like this picture.

But I build it in real network environment.

And there has some problem.

First I just setup rule on the openVswitch (s1), and create slice on FlowVisor which has two flowspace in_port=1, in_port=2.

Then I ping between two host (h1,h2) , it works.

But I think it should be not work when i disable the slice on FLowvisor.

But it still can ping each host.

I'm wonder if I setup rule directly on openVswitch, will it just follow the rule

and won't ask upper controller for getting the rule, SO the Flowvisor slice cannot work?

If someone has any suggestion will be thankful.
