[ovs-discuss] ovs-vsctl: Error detected while setting up 'br0'. See ovs-vswitchd log for details.

[Ashish Kurian]

Dear Guru,

After reboot, If I try to give command ovs-vsctl add-br br0, I get the
following error.

ovs-vsctl: unix:/usr/local/var/run/openvswitch/db.sock: database connection
failed (No such file or directory).

So what I do then is that I give the following commands(from install.md)

sudo ovsdb-server --remote=punix:/usr/local/var/run/openvswitch/db.sock
--remote=db:Open_vSwitch,Open_vSwitch,manager_options
--private-key=db:Open_vSwitch,SSL,private_key
--certificate=db:Open_vSwitch,SSL,certificate
--bootstrap-ca-cert=db:Open_vSwitch,SSL,ca_cert --pidfile --detach
sudo ovs-vsctl --no-wait init
sudo ovs-vswitchd --pidfile --detach

Then I will be able to view result of ovs-vsctl add-br br0 but then I get
the error as mentioned previously when I try to add a bridge.

I did not update the database schema and do not know how to do that. I am
doing everything manually.

Please advice me on the procedure to do this properly.


Best Regards,
Ashish Kurian
