Dear Numan,
Thanks for your patience, it really helps me a lot. And I run it
successfully.
but I still have some another questions in OVN usage, I am sorry to
disturb you.
When I used the OVN in my system, I followed the setup.sh of env1 of
OVN-Tutorial.md.
ovn-nbctl lswitch-add sw0
ovn-nbctl lport-add sw0 sw0-port1
ovn-nbctl lport-add sw0 sw0-port2
ovn-nbctl lport-set-addresses sw0-port1 00:00:00:00:00:01
ovn-nbctl lport-set-addresses sw0-port2 00:00:00:00:00:02
ovn-nbctl lport-set-port-security sw0-port1 00:00:00:00:00:01
ovn-nbctl lport-set-port-security sw0-port2 00:00:00:00:00:02
ovs-vsctl add-port br-int vnet0 -- set Interface vnet0
external_ids:iface-id=sw0-port1
ovs-vsctl add-port br-int vnet1 -- set Interface vnet1
external_ids:iface-id=sw0-port2
In this test, I have two VMs, and the "vnet0" and "vnet1" is the dev.
but I find the OVN didn't work. whatever I do, if only the vnet0 and
vnet1 are in a common OVS br, they always can communicate with each other.
And i run " $ ovn-sbctl show", it didn't show anything. I guess in the
last step, I didn't add the set options in the OVS.
I want to use the OVN to control the two VMs network(just like iptables
to control the connection behaviors). But in the guide book and
examples, they use it in sandbox and doesn't add any VMs, if possible,
could you give me some guidance about the OVN usage with VMs please?
Could you help me? Anyway, thanks for your anwsers and patience, it is
really helpful.
Best regards,
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@troy-PC:/usr/local/etc/openvswitch# ovn-controller
2016-04-22T01:58:44Z|00001|reconnect|INFO|unix:/usr/local/var/run/openvswitch/db.sock:

connected
2016-04-22T01:58:44Z|00003|main|INFO|OVN OVSDB remote not
specified. Waiting...
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
Hi Troy,
In order for you to start ovn youself, you need to do the below
1. Create initial ovn nb and sb dbs using ovsdb-tool
$ovsdb-tool create /opt/stack/data/ovs/ovnnb.db
/opt/stack/ovs/ovn/ovn-nb.ovsschema
$ovsdb-tool create /opt/stack/data/ovs/ovnsb.db
/opt/stack/ovs/ovn/ovn-sb.ovsschema
Please change the path as per your wish.
Refer this link for more information -
https://github.com/openstack/networking-ovn/blob/master/devstack/plugin.sh#L193
2. Start ovsdb-servers.
3. Start ovn-northd and ovn-controller.
Refer this link on how to start these services -
https://github.com/openstack/networking-ovn/blob/master/devstack/plugin.sh#L259
The script file devstack/plugin.sh has answers for all your questions
I guess :).
Thanks
Numan
