Re: [libvirt] [PATCH v2 05/12] graphics: move port definition to listen element

So far we have only two listen types that supports only address:port method, but in the future we may want to add a new different listen type, for example socket. This patch moves the ports values out of graphics unions into listen element. The domain XML will now duplicate the ports from first listen element into the graphics element as we do also for address. This allows us to make part of the graphics code as listen-driven and prepare the code for new listen types. To support migration back to older versions the new attributes from listen elements are not written into migratable XML. Signed-off-by: Pavel Hrdina <phrdina(a)redhat.com&gt;
