Hi Vasilis,
Regarding the hot unplug issue we've been discussing, it's possible to
progress this patch series without fully solving that problem upfront.

Karen Noel suggested that the series could be rolled without the hot
unplug command, so that it's not possible to hit the unsafe case.
This would allow users to hot plug additional memory.  They would have
to use virtio-balloon to reduce the memory footprint again.  Later,
when the memory region referencing issue has been solved the hot
unplug command can be added.

Just wanted to mention Karen's idea in case you feel stuck right now.
