[Qemu-devel] Live migration sequence

[Pavel Fedin]

 Hello!

 I would like to clarify, what is the exact live migration sequence in qemu?

 I mean - there are pre_save and post_load callbacks for VMState structures. Is 
there any determined
order of calling them related to memory contents migration? In other words, is 
there any guarantee
that pre_save is called before RAM migrates, and post_load is called after RAM 
migrates?
 The answer to this question is important for developing vITS live migration, 
where i have to dump
internal ITS state into in-memory tables before the migration starts, and then 
get it back in cache
on destination.

Kind regards,
