[ovs-discuss] [CudaMailTagged] OVN usage in Ubuntu-14.04

[Troy]

Hi, Dear all,

I want to use OVN in Ubuntu-14.04 without sandbox.

In the topic before, Numan told me I should follow the OVN documents in 
the Openstack at this-
http://docs.openstack.org/developer/networking-ovn/deployment_integration_guide.html
But this document only tells something about openstack.
I just want to use OVN in Ubuntu and want it work like iptables.
I install the ovn and ovs in Ubuntu. And I can find the ovn command in 
shell.
But I still cannot run any ovn cmd. When I run "ovn-controller", it showed:

root at troy-PC:/usr/local/etc/openvswitch# ovn-controller

2016-04-22T01:58:44Z|00003|main|INFO|OVN OVSDB remote not specified.

How can I start the database(north-database and sorth-database) ?
Can anyone have any commands to run it correctly?

I look forward your reply.
Best Regards,
Troy
