Hmm it seems I was wrong. I was able to get ovs-openflowd running just
using a datapath with no virtual bridge involved. I thought this was
necessary... When is it necessary, when you are using ovs-vswithd?

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).
