From bb0990d1740f6dced5b50a923677034c9399c213 Mon Sep 17 00:00:00 2001 From: Kirti Wankhede Date: Mon, 23 Nov 2020 19:53:19 +0530 Subject: vfio: Change default dirty pages tracking behavior during migration By default dirty pages tracking is enabled during iterative phase (pre-copy phase). Added per device opt-out option 'x-pre-copy-dirty-page-tracking' to disable dirty pages tracking during iterative phase. If the option 'x-pre-copy-dirty-page-tracking=off' is set for any VFIO device, dirty pages tracking during iterative phase will be disabled.
