My guess is that you're both using the upstreamed OVS kernel module, which does not have the built-in support for tunneling. You can use Linux's native GRE tunnels and just attach them as you would other interfaces to OVS. You'll lose the ability to dynamically set the key and create tunnels through the database, though. If you need that functionality, you'll need to use the kernel module that comes with our distribution.
