But how to get such ring?May be a simple example of solution such problem exists, so could you point meon this example? You bootstrap yourself via xenbus. You have a pre-agreed location in the xenstore hieararchy where the frontend driver writes key-value pairs containing the grant reference for the page containing the message rings, and an event channel for async notifications. See the xenbus.c files in each backend driver directory for examples. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
