Can't ping between 2 hosts using ovs

[Fei Xie]

I followed the tutorial http://groups.geni.net/geni/wiki/GENIExperimenter/Tutorials/OpenFlowOVS/Execute and set up the topology.

When I was doing 2b "sudo ovs-vsctl list-br", it was saying  connection failed, so I installed ovs with this tutorial http://groups.geni.net/geni/wiki/HowTo/InstallOVSInProtoGENI

After that, I'm able to add a bridge and configure the switch.

When I was 3b, I realized that there is no pox installed in the vm. So I git clone it from https://github.com/noxrepo/pox

Then I run "./pox.py --verbose forwarding.l2_learning" in switch and got the message:

s:~/pox% ./pox.py --verbose forwarding.l2_learning

POX 0.2.0 (carp) / Copyright 2011-2013 James McCauley, et al.

DEBUG:core:POX 0.2.0 (carp) going up...

DEBUG:core:Running on CPython (2.7.3/Apr 20 2012 22:39:59)

But when I login to H1 and ping H2, it doesn't work.

Any help on this? Thank you so much!

Hi Fei,

From your discription it looks like that your OVS node was not loaded
with the appropriate image.

How did you do the reservation? Did you use the correct rspec:
http://www.gpolab.bbn.com/exp/OpenFlowOVS/openflowovs-xen-vz.rspec

From the output of pox i see that your switch is not being connected to
the controller. Try using the above rspec and if you are still having
troubles please let us know.

Best,
Niky
