I am working on it, but it's only progressing slowly. The latest
status is that I can run with QEMU/tcg now with Andrea's tree (will
need two more patches to be applied upon from me) however all the
changes are still unmature (e.g., one of the patch is discussing on
the linux-mm list, the other one I haven't discussed with anyone; but
these patches worked for me).
Let me know if want to play with the tree, at least I can share with
you on what I got (so maybe at least you can try to run your live
snapshot with QEMU/tcg with my userfaultfd tree; if error occurred we
can investigate). Again, it is always welcomed if you want to
participate in the kernel work too.
Let me know what you think about it.
Regards,
