It looks like your system ships with a kernel that doesn't support openvswitch.
One solution would be to re-build the kernel enabling support for openvswitch,
but since you're not planning to use the kernel datapath, then it would be
easier if you just edit the ovs-ctl script removing the following line:
insert_mod_if_required || return 1
Without this line, the userspace datapath should still work fine.
