The current Xen scripts are making calls to Linux bridge commands when a VM
is brought up or down.  These calls need to be converted into Open vSwitch
commands.  The preferred way to do this is to actually modify the scripts to
call the equivalent commands, as this generally offers better integration
and a more robust solution.  The other method is to use the Open vSwitch
bridge compatibility layer which will intercept the bridge commands and
convert them into Open vSwitch ones.
