OVS module gives error "FATAL: openvswitch module not found"

Hi,
I am installing quantum and openvswitch on my server.
If i run the command "ovs-vsctl --version" I get the below mentioned output.

ovs-vsctl (Open vSwitch) 1.4.0+build0
Compiled Feb 18 2013 13:13:22

But when I want to check the status of my OVS, I run "ovs-vsctl show" and get the following error:
Sep 25 11:35:31|00001|stream_unix|ERR|/tmp/stream-unix.51717.0: connection to /var/run/openvswitch/db.sock failed: No such file or directory
Sep 25 11:35:31|00002|reconnect|WARN|unix:/var/run/openvswitch/db.sock: connection attempt failed (No such file or directory)

I reload the service using "service openvswitch-switch force-reload-kmod" but again get the error that openvswitch module not found:
FATAL: Module openvswitch not found.
 * Inserting openvswitch module
 * not removing bridge module because bridges exist (qbr2f96c5e6-58 qbr47f4dd43-92 qbra6cc5819-e1 qbrb032166b-da)
Module has probably not been built for this kernel.
Install the openvswitch-datapath-source package, then read
/usr/share/doc/openvswitch-datapath-source/README.Debian

Can anyone help me or guide me what I am doing wrong here?
Thanks.
