I imagine that you built against some kernel version other than the
one that is running.
Run "modinfo" on openvswitch_mod.ko and on a module built for the
running kernel, e.g.:
% /sbin/modinfo openvswitch_mod.ko
% /sbin/modinfo /lib/modules/`uname -r`/kernel/net/bridge/bridge.ko
Compare the "vermagic" lines output by the two commands. If they
differ, then Open vSwitch was built for the wrong kernel.
