[Qemu-devel] [PATCH 0/4] Xen, introducing dirty log for migration.

[Anthony PERARD <anthony.perard@citrix.com>]

Hi,

This patch set will fix live migration under Xen. For this I introduce a new
QMP command to switch global-dirty log and few calls (in exec.c and memory.c)
to xen set_dirty function.

It unfortunatly necessary to adds new calls because
cpu_physical_memory_set_dirty is not call if the memory is already consider as
dirty by QEMU. But Xen does not handle the same dirty bitmap.

Thanks for your reviews,


Anthony PERARD (4):
  QMP, Introduce set-global-dirty-log command.
  xen: Introduce xen_modified_memory.
  exec, memory: Call to xen_modified_memory.
  xen: Always set the vram dirty during migration.
