From c5705a7728b4a6bc9e4f2d35911adbaf28042b25 Mon Sep 17 00:00:00 2001 From: Avi Kivity Date: Tue, 20 Dec 2011 15:59:12 +0200 Subject: vmstate, memory: decouple vmstate from memory API Currently creating a memory region automatically registers it for live migration. This differs from other state (which is enumerated in a VMStateDescription structure) and ties the live migration code into the memory core. Decouple the two by introducing a separate API, vmstate_register_ram(), for registering a RAM block for migration. Currently the same implementation is reused, but later it can be moved into a separate list, and registrations can be moved to VMStateDescription blocks.
