[Openstack] Question on virt interfaces

Hi all,

I was wondering about the following I am seeing in code:

Say in xenapi_conn.py I see:

    def live_migration(self, context, instance_ref, dest,
                       post_method, recover_method):
        """This method is supported only by libvirt."""
        return

But doesn't libvirt also support xenapi/xenserver?
So why wouldn't this method say just proxy into libvirt?
Seems odd to have an interface which has functions which can be only implemented by a single implementation (isn't it not really an interface if its not supported by all impls??).
