[Qemu-devel] [PATCH V5 00/17] COLO: integrate colo frame with block replication and COLO proxy |

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-18mar10
Please review, thanks.
V5:
- Addressed Markus's comments add new command to
query COLO status(patch 11/17).
- Rebased on upstream codes.
- Fixed qapi header problem in patch 10/17.
- Fixed the conflict of "qemu_anon_ram_alloc()" in patch 07/17.
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.
Zhang Chen (10):
filter-rewriter: fix memory leak for connection in
connection_track_table
colo-compare: implement the process of checkpoint
colo-compare: use notifier to notify packets comparing result
COLO: integrate colo compare with colo frame
COLO: Add block replication into colo process
COLO: Remove colo_state migration struct
ram/COLO: Record the dirty pages that SVM received
qapi: Add new command to query colo status
filter: Add handle_event method for NetFilterClass
filter-rewriter: handle checkpoint and failover event
zhanghailiang (7):
COLO: Load dirty pages into SVM's RAM cache firstly
COLO: Flush memory data from ram cache
qmp event: Add COLO_EXIT event to notify users while exited COLO
savevm: split the process of different stages for loadvm/savevm
COLO: flush host dirty ram from cache
COLO: notify net filters about checkpoint/failover event
COLO: quick failover process by kick COLO thread
