From 4cc856fabae1447d53890e707c70f257a7691174 Mon Sep 17 00:00:00 2001 From: zhanghailiang Date: Thu, 2 Apr 2015 19:26:31 +0000 Subject: [PATCH] kvm-all: Sync dirty-bitmap from kvm before kvm destroy the corresponding dirty_bitmap Sometimes, we destroy the dirty_bitmap in kvm_memory_slot before any sync action occur, this bit in dirty_bitmap will be missed, and which will lead the corresponding dirty pages to be missed in migration. This usually happens when do migration during VM's Start-up or Reboot.
