The thing is that linux bridge and openvswitch is mutually exclusive
since both needs to load kernel modules which is supposed to hook into
the network stack the same place. What you discover is that when
migrating between a linux bridge and an openvswitch node the running vm
talks either language but not both at the same time (so to speak)
