Hi ,
I have configured openvswitch(1.4) in centos-6.2 along with KVM. I have
created two VM's , on VM1 and VM2 i have installed web server and
database server respectively. I have followed below steps :
ovs-vsctl add-br br0
ovs-vsctl add-port br0 eth1 trunks=5,11
ovs-vsctl del-port vnet0
ovs-vsctl add-port br0 vnet0 tag=5
ovs-vsctl del-port vnet1
ovs-vsctl add-port br0 vnet1 tag=11
ovs-vsctl set interface eth1 other-config:enable-vlan-splinters=true
Vnet0 is the interface for VM1
Vnet1 is the interface for VM2
But i am facing a problem , when my webserver(VM1) access the database
server(vm2) then my web application becomes slow. if the same webserver
use the database which is outside the openvswitch lan , then web
application becomes fast. Also check the ifconfig output , i don't know
why eth1 has different sub interfaces.

I have configured the debug logs also and getting the below messages :

Any idea how to solve this problem. Thanks in advance.
