[Qemu-devel] [PATCH V5 0/5] Xen, introducing dirty log for migration.

[Anthony PERARD]

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.

Change since v5:
  - fix initial version number for the xen-set-global-dirty-log QMP command.

Change since v4:
  - call xen_modified_memory in cpu_physical_memory_set_dirty_range instead of
    calling it from memory_set_dirty.

Change since v3:
  - Coding style of patch 2
  - Reword last patch comment

Change since v2:
  - renamed set_dirty_helper to invalidate_and_set_dirty.
  - in the last patch, set vram as dirty if the xen call fails, instead of only
    during migration.

Change v1-v2:
  - New patch to set dirty if not, in exec.c
    => only one place to add the xen call in exec.c
