[ovs-discuss] Simple MPLS experiment with OpenvSwitch

Thanks for replying Ben. I changed the Mininet python file to use a UserSwitch :

def emptyNet():

    "Create an empty network and add nodes to it."

    net = Mininet( controller=lambda name: NOX ( name, 'NOXSwitch' ),
switch=UserSwitch )


but now when I fire up Mininet I don't the switch when using utilities
ovs-vsctl and ovs-dpctl

$ sudo ovs-vsctl show
01407762-26a9-43f5-9094-7b9bcf45eacc
$ sudo ovs-dpctl show
system at ovs-system:
	lookups: hit:2019 missed:302 lost:0
	flows: 0
	port 0: ovs-system (internal)

I have been using the kernel module so far, so please pardon my
ignorance. What am I doing wrong?
