Thank you for your response. Yes, I would like to work on some task, and
eventually I would like to use it as my student project. For example, it
might be possible to implement the technique from the article Post-Copy,
Hines, 2009: demand paging, active push, prepaging and dynamic
self-ballooning. As far as I understood from the postcopy documentation,
the pages are pushed sequentially, but it is possible to implement a new
prepaging strategy. Or are there any obstacles to implementing the ideas of
this paper in QEMU?
