When creating instances you can sometimes see messages like these in the log:

Open vSwitch Switch is not configured to listen on a TCP connection by default.
Nova's default has recently changed [0].
Perhaps we should point Nova at the Unix socket Open vSwitch listens to?
Often instance creation succeeds, but I also see instance creation failures that correlate with the above messages.
I have yet to establish any causation between the two events.
