No access to default gw from VM

[Yuli]

Hello

I have the latest version of the Dragonflow.

After creating VM I can not get ping to the router.

Here how to reproduce.

1. Create a net and a subnet
2. Attach subnet to router
3. Create VM and attach it to the network created above.

I was doing this is demo tenant.

No ports is assigned in ovs to the router.

As a result no port created for the router, only for the vm.

I created network: test10 and privet net: test10-priv

I tested under the latest devstack and ubuntu 14.04 server. It works. The VM can ping both subnet gateway and router gateway. I attached the screenshot.

Could you provide any details about your environment, like dump-flows?
