What happens at boot is this:
* OVS tears down and destroys all bridges, because XenServer
expects to re-create each one at boot.
* OVS refreshes the manager (OVSDB connection) from the
XenServer (XAPI) database.
* XenServer creates each of the bridges. No controller is
* The manager is supposed to set the controller for each
bridge as it likes, using the OVSDB connection to do so.
