My guess is that you loaded the version of openvswitch.ko that shipped with your distribution kernel (or an earlier version of out of tree OVS). I would do a clean build of the OVS tree, unload all OVS related modules, and then use insmod to specific load the right ones from the OVS directory. Once that works, you should also be able to do make modules_install to install the new OVS modules in the right search path. _______________________________________________ dev mailing list dev@openvswitch.org http://openvswitch.org/mailman/listinfo/dev
