From d07824810dbc4195ce7473e899baabf4d2c8b3d9 Mon Sep 17 00:00:00 2001 From: Konrad Rzeszutek Wilk Date: Fri, 1 Mar 2013 16:49:42 -0500 Subject: [PATCH] xl: export 'outstanding_pages' value from xcinfo This patch provides the value of the currently outstanding pages claimed for a specific domain. This is a value that influences the global outstanding claims value (See patch: "xl: 'xl info' print outstanding claims if enabled") returned via xc_domain_get_outstanding_pages hypercall. This domain value decrements as the memory is populated for the guest and eventually reaches zero. With this patch it is possible to utilize this field.
