Comment 11 for bug 1649124

I'm not sure if this is the cause of the problem but if I escape the " when trying to run it like this:

ovs-vsctl --timeout=10 --oneline --format=json -- --id=@manager create Manager target=\"ptcp:6640:127.0.0.1\" -- add Open_vSwitch . manager_options @manager

I then get this error message:
ovs-vsctl: transaction error: {"details":"Transaction causes multiple rows in \"Manager\" table to have identical values (\"ptcp:6640:127.0.0.1\") for index on column \"target\".
