No this is not correct. Current QEMU SMMU device *does* support
migration (see VMStateDescription) as well as qemu virtio-iommu device.
so for instance if you run a guest with smmuv3 and protected virtio-pci
devices this is supposed to be migratable. If it does not work this is
bug and this should be fixed ;-)
