From b0a46a333acfd78da56cf6aebb95f4a5dfb3a4f2 Mon Sep 17 00:00:00 2001 From: Jan Kiszka Date: Sat, 2 May 2009 00:22:51 +0200 Subject: kvm: Add missing bits to support live migration This patch adds the missing hooks to allow live migration in KVM mode. It adds proper synchronization before/after saving/restoring the VCPU states (note: PPC is untested), hooks into cpu_physical_memory_set_dirty_tracking() to enable dirty memory logging at KVM level, and synchronizes that drity log into QEMU's view before running ram_live_save().
