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

[Ashish Kurian]

Dear All,

Some where I also read that I have to install openvswitch-datapath-source
and openvswitch-brcompat. Also in another forum read that I have to update
the database schema. Can you advice if these are necessary and if so, how
to update the database schema?

Best Regards,
Ashish Kurian
