Series | COLO: integrate colo frame with block replication and COLO proxy | expand |
Hi~ All~ No news for a long time, this is the last part to make COLO running in upstream. Any comments for this series?

From: Zhang Chen <chen.zhang@intel.com> Hi~ COLO Frame, block replication and COLO proxy(colo-compare,filter-mirror, filter-redirector,filter-rewriter) have been exist in qemu for long time, it's time to integrate these three parts to make COLO really works. In this series, we have some optimizations for COLO frame, including separating the process of saving ram and device state, using an COLO_EXIT event to notify users that VM exits COLO, for these parts, most of them have been reviewed long time ago in old version, but since this series have just rebased on upstream which had merged a new series of migration, parts of pathes in this series deserve review again. We use notifier/callback method for COLO compare to notify COLO frame about net packets inconsistent event, and add a handle_event method for NetFilterClass to help COLO frame to notify filters and colo-compare about checkpoint/failover event, it is flexible. For the neweset version, please refer to: https://github.com/zhangckid/qemu/tree/qemu-colo-18jan19 Please review, thanks. V4: - Address Eric's comments in patch 10/16. - Rebase on upstream codes. - Fix mingw compile error in patch 02/16. - Fix some comments. - Fix conflect with the patch "migration: remove "enable_colo" var" in patch 06/16. V3: - Address community comments from V2. - Rebase on upstream codes. - Fix several bugs. - Splite shared disk part to indepentent patch set. - Optimize codes.
