[ovs-discuss] Getting OpenFlow Set Up

Hello,

After much hard work, troubleshooting, and experimenting, I was finally 
able to get OpenFlow up and running! However, I am now trying to make 
the steps concrete and I have a few questions.

I created my virtual bridge vbr0 using ovs-vsctl while ovs-vswitchd was 
running. I now want to use ovs-openflowd instead. However, it seems I 
cannot form a connection between ovs-controller and ovs-openflowd unless 
I do an ifconfig on vbr0. This, however, requires ovs-vswitchd to be 
running. How can I do this using only ovs-openflowd?

Also, I'm not exactly sure which IP address I should use for the 
datapath, and which IP address I should use for running in-band 
communication. I tried using ptcp: to connect the controller and 
OpenFlow switch but this didn't work.

My set-up is as follows:

- Open vSwitch runs in a Virtual Machine.
- Other vm hosts connect to the switch vm via an internal network (one 
for each host).
