r18383 mark video memory as ram, and make all valid pages migrated, including vlapic page (0xFEE00), and share page(0xFFFFF). An extra memory population for lapic page would override previous mapping then cause HVM guest with vlapic acceleration hang. This patch from Keir makes mmio page as invalid, so xc_domain_save skip vlapic page. Share page is safe, as the mapping is not set up until after normal guest memory is restored. -- best rgds, edwin _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel
