Hi,
I am trying to create a simple two tenant logical network on a single chassis
using OVN as shown below.

. ( 100.0.0.3 ) ( 100.0.0.4 ) .
. \ / \ / .
. '------------------' '------------------' .

Here is the OVN commands I used to create this topology.
ovn-nbctl lswitch-add sw0
ovn-nbctl lport-add sw0 sw0-port1
ovn-nbctl lport-add sw0 sw0-port2
ovn-nbctl lport-set-macs sw0-port1 00:00:00:00:00:01
ovn-nbctl lport-set-macs sw0-port2 00:00:00:00:00:02
ovs-vsctl add-port br-int tap0 -- \
set Interface tap0 external-ids:iface-id=sw0-port1
ovs-vsctl add-port br-int tap1 -- \
set Interface tap1 external-ids:iface-id=sw0-port2
ovn-nbctl lswitch-add sw1
ovn-nbctl lport-add sw1 sw1-port1
ovn-nbctl lport-add sw1 sw1-port2
ovn-nbctl lport-set-macs sw1-port1 00:00:00:00:00:03
ovn-nbctl lport-set-macs sw1-port2 00:00:00:00:00:04
ovs-vsctl add-port br-int tap2 -- \
set Interface tap2 external-ids:iface-id=sw1-port1
ovs-vsctl add-port br-int tap3 -- \
set Interface tap3 external-ids:iface-id=sw1-port2
tap0, tap1, tap2 and tap3 are the physical network interfaces attached to the
VMs.
The issue is all the VMs are added to same network even though they belongs
different logical network. There is no vlan tag /tunneling configured to any of
these ports whatsoever.
I confirmed that the Southbound DB has populated correctly with the two set of
logical datapath rules, but its not getting populated at the forwarding path.
I am using Ubuntu with kernel 3.13 and OVN compiled from origin/ovn branch.
My north bound configuration can be seen below.
sugesh@silpixa00389816:~/repo/OVN# ovn-nbctl show
lswitch 7816e518-7ea0-48df-aae6-0e0b8e9f87fc (sw0)
lport sw0-port2
macs: 00:00:00:00:00:02
lport sw0-port1
macs: 00:00:00:00:00:01
lswitch 40c94a0e-c93d-4f5b-b9df-0330ad5cb5f8 (sw1)
lport sw1-port1
macs: 00:00:00:00:00:03
lport sw1-port2
macs: 00:00:00:00:00:04
It seems to me like the ovn-controller cannot access the OVN_Southbound DB (the
controller logs message shows "2015-07-10T10:45:15.771Z|00031|main|INFO|OVN
OVSDB remote not specified. Waiting...") to configure the OVS.
I started the controller and northd with following commands which doesn't take
any argument as such.
ovn-ctl start_northd
ovn-ctl start_controller
Could someone help me out to figure out what has been configured wrongly here??
