Hmmm, strange that it isn't working, we run nox with ovs all the time.
Tomorrow I'll be pushing a major update to nox on noxrepo. It may be
that the older, public version of Nox has some issue we've not run into ...

I just run it with pyswitch --- ./nox_core -v -i ptcp:2525 pyswitch

What command line args are you passing to Nox when you run it?
Thanks, Justin.
It works without any controller and also works with ovs-controller. I
guess it's a NOX issue. Do I have to do anything special with NOX? I'm
just using the same NOX that works with openflow reference
implementation 0.8.9. I tried compiling NOX again by giving
openvswitch to --with-openflow option, but didn't work because some
header files mismatch.
One more thing - I noticed that I have to bring up interfaces for the
switch manually, e.g., "ifconfig eth1 up". I wanted to verify if this
is the case, since I don't do it when I run openflow reference
implementation.

I don't think you need to set this key.
NOX is configured as an out-of-band controller, and connectivity is
fine. With this configuration file, I run ovs-vswitchd with -v, then I
get the log copied at the end of this email. It seems that there is no
error. However, when I actually bring up 2 hosts and try to ping each
other, ARP requests never pass through. I used tcpdump to verify that
either eth1 or eth2 receives the ARP requests, and they do receive the
packets.
What NOX applications are you running? I'd recommend first trying to run
ovs-vswitchd without connecting to a controller. That way, you can at least
determine whether ovs-vswitchd is receiving traffic. Without a controller,
it should just work like a learning switch. If that looks okay, try running
ovs-controller (it's available in the "utilities" directory), since it's
much simpler than NOX. If that looks okay, then it's probably a NOX
configuration issue.
I'm a bit surprised that you're not seeing packet-in messages reported in
the logs below. It appears that you only have four seconds of logging. I
assume you waited longer than that, correct?
