[Xen-devel] [PATCH Remus v2 00/10] Remus support for Migration-v2

[Yang Hongyang <yanghy@xxxxxxxxxxxxxx>]

This patchset implement the Remus support for Migration v2 but without
memory compressing.

The series can be found on github:
https://github.com/macrosheep/xen/tree/Remus-newmig-v2

PATCH 1-7: Some refactor and prepare work.
PATCH 8-9: The main Remus loop implement.
PATCH 10: Fix for Remus.

v2:
 - move to_send bitmap to ctx->save union and rename it to dirty_bitmap
 - introduce setup() and cleanup() on save
 - rename send_some_pages to send_dirty_pages
 - remove "defer the setting of HVM_PARAM_IDENT_PT", it should be fixed
   on hypervisor side
 - the last patch still there for my test purpose until Andrew find a
   suitable solution(which we commented on the first series) :)

v1:
