In opendaylight carbon when installing feature:install odl-ovsdb-southbound-impl
I get the following exception

I also get it each time I start the ODL
The java.net.BindException: Address already in use
means that something on the host you are running already holds one of the ports which OpenDaylight wants to open. This could also happen if you start OpenDaylight twice. Often the actual port is shown in this kind of error, and then you can use (on Linux) netstat to find what process is already on that port. In this case for some reason its not showing which port; I don't know why. So you could just do some trial and error and stop other things you are running one after the other one, and retry ODL, until you'll find what it is.
