# service openvswitch-switch force-reload-kmod
 * Inserting openvswitch module
FATAL: Error inserting brcompat (/lib/modules/3.5.0-24-generic/kernel/brcompat.ko): Unknown symbol in module, or unknown parameter (see dmesg)
 * Inserting brcompat module
Module has probably not been built for this kernel.

i remove the module provided by kernel, then it works:

#mv /lib/modules/3.5.0-24-generic/kernel/net/openvswitch/openvswitch.ko /tmp
#depmod -a
#/etc/init.d/openvswitch-switch start                    <<<
 * Inserting openvswitch module
 * Inserting brcompat module
 * Starting ovsdb-server
 * Configuring Open vSwitch system IDs
 * Starting ovs-vswitchd
 * Starting ovs-brcompatd
 * iptables already has a rule for gre, not explicitly enabling
