I have finished reviewing this revision.

Please update the wiki page with the latest status, especially
limitations like no dirty memory logging (used by migration, TCG, VGA),
no MSI interrupts, no PCIe, no IOMMU support, etc.

Please name the machine type x-remote and the object -object
x-remote-object. "x-" is the convention for experimental features in
QEMU. It means that the interface is not stable and might change between
releases.
