[Qemu-devel] [PATCH V8 00/17] COLO: integrate colo frame with block replication and COLO proxy |

Hi~ All~
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-18jun1
Please review, thanks.
V8:
- Rebased on upstream codes.
- Addressed Markus's comments in patch 10/17.
- Addressed Markus's comments in patch 11/17.
- Removed some comments in patch 4/17.
- Moved the "migration_bitmap_clear_dirty()" to suitable position in
patch 9/17.
- Rewrote the patch 07/17 to address Davie's comments.
- Moved the "qemu_savevm_live_state" out of the
qemu_mutex_lock_iothread.
- Fixed the bug that in some status COLO vm crash with segmentation fault.
V7:
- Addressed Markus's comments in 11/17.
- Rebased on upstream.
V6:
- Addressed Eric Blake's comments, use the enum to feedback in patch 11/17.
- Fixed QAPI command separator problem in patch 11/17.
Zhang Chen (13):
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
COLO: Load dirty pages into SVM's RAM cache firstly
ram/COLO: Record the dirty pages that SVM received
COLO: Flush memory data from ram cache
qapi: Add new command to query colo status
savevm: split the process of different stages for loadvm/savevm
filter: Add handle_event method for NetFilterClass
filter-rewriter: handle checkpoint and failover event
zhanghailiang (4):
qmp event: Add COLO_EXIT event to notify users while exited COLO
COLO: flush host dirty ram from cache
COLO: notify net filters about checkpoint/failover event
COLO: quick failover process by kick COLO thread
