I am not sure whether the kernel is flexible enough to handle this.  Is
it possible to configure kernel VXLAN tunnels at the same time as
running your server?  If it is possible, then maybe OVS userspace can be
adapted to do it.  If it is not possible, then it would take kernel
changes (outside of the OVS kernel module, probably) for OVS userspace
to be able to do it; while that does not make it impossible, it does
make it a bigger job.
