Migrating a VM during reboot sometimes results in differences between the source and destination in the SMRAM area. This is because migration_bitmap_sync() only fetches from KVM the dirty log of address_space_memory. SMRAM memory slots are ignored and the modifications to SMRAM are not sent to the destination.
