You'll have a tunnel to each Hypervisor (not tenant) that is
registered with quantum via the quantum-openvswitch-agent that runs on
each Hypervisor.

If you run:
sudo ovs-ofctl dump-flows br-tun
sudo ovs-ofctl dump-flows br-int
you'll see the flows that are doing this for you. The
quantum-openvswitch-agent will install these flows for you when a VM
lands on the corresponding Hypervisor.
