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 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
Anthony PERARD (5):
QMP, Introduce xen-set-global-dirty-log command.
xen: Introduce xen_modified_memory.
exec: Introduce helper to set dirty flags.
exec, memory: Call to xen_modified_memory.
xen: Set the vram dirty when an error occur.
