Module openvswitch not found when starting openvswitch service

Hello, everyone here.

I am new for Openstack, in these days I've been trying to install an openstack Icehouse infrastructer with three nodes (controller node + network node + compute node) by following the offcial installation documentation for CentOS. When I finished the installation of neutron on the network node in chapter 7: Add a networking service, and trying to start openvswitch service. Here comes the error:

==================================================

[root@network ~]# service openvswitch start ovsdb-server is already running. Inserting openvswitch module FATAL: Module openvswitch not found. [FAILED] Enabling remote OVSDB managers [ OK ]

Actually I am very sure I've installed all the necessary rpms for neutron service on the network node (openstack-neutron + openstack-neutron-ml2 + openstack-neutron-openvswitch) and configured all the necessary parameters carefully. I really don't see this error coming.

Could you please help me to fix this problem?

Thanks advance.

======================================

Here is the basic information for my environment:

CentOS 6.5 + Icehouse + Three-node architecture with Openstack Networking (neutron)

Module openvswitch not found when starting openvswitch service
