Here is the what I have right now for post copy chardevice.
The sample user land will follow.
It would give you more concrete idea and help further discussion, I hope.
This is just for discussion, so it's incomplete.
I'm open to other ideas and quite happy to throw away this patch and
go for
Sample user land program for testing the post copy chardevice.

Hello everyone,
so basically this is a tradeoff between not having a long latency for
the migration to succeed and reducing the total network traffic (and
CPU load) in the migration source and destination and reducing the
memory footprint a bit, by adding an initial latency to the memory
accesses

* What's is postcopy livemigration
It is is yet another live migration mechanism for Qemu/KVM, which
implements the migration technique known as postcopy or lazy
migration. Just after the migrate command is invoked, the execution
host of a VM is instantaneously switched to a destination host.
