I am trying to test recipe described in

My hardware is IBM BladeCenter with two blades and internal
network switch.  RHEL 5.5 with openvswitch 1.0.1.

eth1 is a physical network interface, connected to network
switch.  For each port there's list of allowed vlans and default
vlan tag.

Now I'm executing commands on two hosts:

(1) ovs-vsctl -- --may-exist add-br vnetbr
(2) ovs-vsctl -- --may-exist add-port vnetbr eth1
(3) ip li set vnetbr up
(4) ovs-vsctl -- --may-exist add-port vnetbr vnetbr3140 tag=3140 \
              -- set Interface vnetbr3140 type=internal
(5) ip li set vnetbr3140 up
(6.1) ip ad add dev vnetbr3140
(6.2) ip ad add dev vnetbr3140

Now, on host 1 I start tcpdump on interface vnetbr3140 and on
host 2 I start ping  Packets doesn't reach host 1.

Tried to replace command (4) with

ovs-vsctl -- --may-exist add-br vnetbr3140 vnetbr 3140 \
          -- set Interface vnetbr3140 type=internal

No effect either.  Everything works fine if I create VLANS with
