If your problem is similar to the first few google hits, then some part 
of your configuration is probably calling "service something restart" or 
"systemctl restart something".  The service being restarted requires 
network.target to be available, which only happens after the interfaces 
are all up, which is a deadlock condition.

If you provide all of the configuration files you edited to enable 
openvswitch, we might be able to give you more specific advice. Your 
original question was quite vague.
