10 Migration of VFIO devices consists of two phases: the optional pre-copy phase,
11 and the stop-and-copy phase. The pre-copy phase is iterative and allows to

142 phase. So, a page marked as dirty will be copied to the destination in both
143 phases. Copying dirty pages in pre-copy phase helps QEMU to predict if it can
144 achieve its downtime tolerances. If QEMU during pre-copy phase keeps finding
145 dirty pages continuously, then it understands that even in stop-and-copy phase,
