OVS 2.5.1 Tunnel Problem, No Network inside VM

Hello, After updating OVS to 2.5.1 no vxlan tunnels can't be created automaticaly within br-tun. To check we can remove all VM from host so OVS will have no tunnels to the other agents. Then we create a new VM and OVS tells failed to query port : Invalid argument when tries to get tunnels. I'm using OVS 2.5 on neutron server.

2016-12-10T19:07:48.249Z|00106|dpif|WARN|system@ovs-system: failed to query port : Invalid argument 2016-12-10T19:07:48.877Z|00107|bridge|INFO|bridge br-int: added interface 25b5cc64-b59f-4624-8bdf-def533e354f6 on port 3

I'd be more than happy if you can help me with this issue.
