This would be nice but it can't be this simple. The first reason is because OVS consists of daemons that run in a polling loop. Resolving DNS names can take seconds. We can't afford to pause everything in the main loop for that long. This could be fixed by either spawning a thread for name resolution or by using an asynchronous name resolution library. Second, we've historically not even bothered with name resolution for ovs-vswitchd because of in-band control issues. Basically, that means that ovs-vswitchd needs to connect to the OpenFlow controller before it knows much about the network structure, including about how to reach the name server, and there's a sort of chicken-and-egg problem. This only applies to ovs-vswitchd and specifically when in-band control is in use though. So, basically, I support this, but it needs to be more sophisticated.
