There's no question about that. Our aim here is to allow a save/restore or migration to fail gracfully by resuming execution in the original domain context. Currently that is simply not possible, but it's not hard to fix. -- Keir _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxx http://lists.xensource.com/xen-devel
