Thread-topic: [Xen-API] Re: [Xen-devel] [XCP] new version available
Furthermore, you can still switch between the vswitch and linux bridging 
network subsystems by altering the file /etc/xensource/network.conf ("vswitch" 
or "bridge"). The default is now "vswitch", and eventually the linux bridging 
option will be removed.

See http://openvswitch.org/ for more information about the vswitch.

If you are asking whether this change will cause an XCP host to try and
configure/manage your physical switches then the answer is no. This
change is purely to replace the Linux bridging implementation used on an
XCP host with an openvswitch based solution.

It doesn't change any XenAPI calls but it does necessarily change the
implementation of the interactions between xapi and host's network
subsystem. Mainly those changes are in ocaml/netdev/netdev.ml and in
things like the interface-reconfigure and VIF hotplug scripts.
