[Qemu-devel] [PATCH COLO-Frame (Base) v20 00/17] COarse-grain LOck-stepping(COLO) Virtual Machines for Non-stop Service (FT)

[zhanghailiang]

This is the 20th version of COLO frame series.

COLO Block replication and proxy (COLO compare) series are both been
merged into upstream already. And further works can be done now to
realize the full COLO feature.

Athough there are still no feedbacks from community for this part,
But I would like to rebase this series to the recent upstream.

Compared with last version, i dropped another five patches from
this series, only keep the minimum patch sets to realize COLO
checkpoint and failover process, just for easy understanding and review.
