I'm still a little confused as to what it is you're trying to accomplish; if you create a GRE port like this
# ovs-vsctl add-port br0 tun0 -- set interface tun0 type=gre options:remote_ip=192.168.1.10 the tunnel should work with no problems. From what you're saying, it seems like you're creating a tunnel and trying to add an additional tunnel adapter? What does your topology look like?
