Thanks, if you are going to merge some of the patches, there is the
latest version of `COLOPre' patchset:
https://github.com/macrosheep/xen/tree/colo-v9
The latest 26 commits.
I think all patches are ready to be merged except:
7 libxl/remus: init checkpoint_callback in Remus checkpoint callback
11 tools/libxc: support to resume uncooperative HVM guests
20 tools/libx{l,c}: add back channel to libxc
