Have you added flows on "br2"? As per  last row second column, you have
passed br0 as input.
Also share dump-flow using ovs-ofctl.

Subject:  [ovs-discuss] ovs-ofctl add-flow

Hi everbody
I¹m new in ovs.
I want to connect two VMs via ovs port and ping them without connecting to a
controller. But after adding flows, they cannot see each other. Could
anybody help please
This is what Ive done:
 
  VM1 root at mininet-vm:/home/mininet# ovs-vsctl show
987c42d0-eab0-43d9-a32b-4246973706c2     Bridge "br0"         Port "eth0"
Interface "eth0"         Port "br0"             Interface "br0"
type: internal         Port "patch0"             Interface "patch0"
type: patch                 options: {peer="patch2"}  ovs_version: "1.4.3"
 Ports root at mininet-vm:/home/mininet# ovs-dpctl show system at br0:
lookups: hit:977 missed:427 lost:0         flows: 2         port 0: br0
(internal)         port 1: eth0          port 2: patch0 (patch: peer=patch2)
 Adding flows ovs-ofctl add-flow br0 in_port=1,actions=output:2   ovs-ofctl
add-flow br0 in_port=2,actions=output:1       VM2
root at mininet-vm:/home/mininet# ovs-vsctl show
987c42d0-eab0-43d9-a32b-4246973706c2     Bridge "br2"         Port "patch2"
Interface "patch2"                 type: patch                 options:
{peer="patch0"}         Port "br2"             Interface "br2"
type: internal         Port "eth0"             Interface "eth0"
ovs_version: "1.4.3"
 Ports root at mininet-vm:/home/mininet# ovs-dpctl show system at br2:
lookups: hit:789 missed:672 lost:0         flows: 2         port 0: br2
(internal)         port 1: eth0          port 2: patch2 (patch: peer=patch0)
 Adding flows ovs-ofctl add-flow br0 in_port=2,actions=output:1   ovs-ofctl
add-flow br0 in_port=1,actions=output:2
