It sounds like Open vSwitch is operating correctly.  I don't know what a
"UserSwitch (Reference Switches)" is; if it's not some configuration of
Open vSwitch, then you might want to ask about it on a mailing list that
focuses on that switch.  If it is a configuration of Open vSwitch, then
maybe you should explain further.

Not everyone on this mailing list knows much about Mininet; I don't.
