Subject: [Qemu-devel] Live migration sequence
Date: Thu, 08 Oct 2015 14:39:35 +0300	[thread overview]
Message-ID: <008b01d101be$0228d720$067a8560$@samsung.com> (raw)

 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,
