Subject: Re: [ovs-discuss] Error with ovs-vsctl

Once I got the previous error and if I try to add a bridge:
sudo ovs-vsctl add-br br1
Then I get the error:
ovs-vsctl: Error detected while setting up 'br1'. See ovs-vswitchd log for 
details.
Thanks,
Priya

What error are you talking about?  The log is hundreds of lines long and
I don't see an obvious error there.
