Detailed Summary
Migration and live migration have several parts that are suboptimal. This describes way to improve it.
Status
This is the roadmap, features are integrated upstream as they are done.
TODO
- split migration in its own thread/subroutine
This allows several improments: * monitor can be used on migration target * vcpus/iothreads can work while live migration part is working * we can remove several layers of buffering (due to the mainloop design, we are forced to have several layers of buffering).
- split foo_live_migration_calls() onto its parts:
* foo_setup() (was stage 1) * foo_save_live() (was stage 2) * foo_save_rest() (was stage 3, better name needed) * foo_cancel() (was stage -1)
Code
The code still not merged is currently kept in several branches of this git repository:
