This series aims to fix the regression, and should unblock several osstest branches. The following report is from osstest with this series applied: http://logs.test-lab.xenproject.org/osstest/logs/148979/ Note the last patch (4/4) is the one that actually fixes the issue. Xen will always use the Ack on exit feature so patches 2/4 and 3/4 don't change the functionality when running a nested Xen, as it always requires SVI to be updated. Thanks, Roger.
