The thing that I want to do is to install a flow per table so I'm trying to undestand how does this works

Thanks Murphy, 
I'm using the ovs 1.4.6. So I think that would be the problem I'll change to one more recent and see if the problem is fix 
Thanks so much

Are you using a switch that has the NXT_SET_PACKET_IN_FORMAT and NXT_FLOW_MOD_TABLE_ID Nicira extensions?
I'm not sure which version of Open vSwitch is the first to support these... maybe 1.8?
Glancing at the code, I actually don't immediately see where the new packet-in format is actually used.  You could try commenting out the lines which try to turn it on (around 81-83 of l2_nx.py in my local copy).
(As a sidenote, you're supposed to pass --convert-packet-in to openflow.nicira.  The docs show this, but it's not clear enough -- I'll fix it in carp.  But if you're going to try to disable this feature anyway, it shouldn't matter.)

And I lose communication with the hosts
I don't see where is the problem and don't know how to correct it.
Thanks in advance
