I kept this in migration.c to call qemu_savevm_state_begin. (The way it is done currently. i.e. to keep access to FdMigrationState in migration.c) Calling it from buffered_file.c would be inconsistent in that sense. or we will have to call it from the iothread before spawning the migration thread.
Right, I missed that. Perhaps you can call it the first time put_ready is called.
Also why is the separation between FdMigrationState and QEMUFileBuffered is required. Is QEMUFileBuffered designed to use also for things other than migration?
No, but let's keep it this way for now. It may be an annoyance, but it also helps making a reusable architecture, and it can probably be cleaned up substantially with thread support.
