[Qemu-block] [PATCH COLO-BLOCK v8 00/18] Block replication for continuous checkpoints |
Date: |
Tue, 7 Jul 2015 16:42:58 +0800 |
Block replication is a very important feature which is used for
continuous checkpoints(for example: COLO).
You can the detailed information about block replication from here:
http://wiki.qemu.org/Features/BlockReplication
Usage:
Please refer to docs/block-replication.txt
You can get the patch here:
https://github.com/coloft/qemu/tree/wency/block-replication-v8
You can get the patch with framework here:
https://github.com/coloft/qemu/tree/wency/colo_framework_v8
TODO:
1. Continuous block replication. It will be started after basic functions
are accepted.
Wen Congyang (18):
Add new block driver interface to add/delete a BDS's child
quorum: implement block driver interfaces add/delete a BDS's child
hmp: add monitor command to add/remove a child
introduce a new API qemu_opts_absorb_qdict_by_index()
quorum: allow ignoring child errors
introduce a new API to enable/disable attach device model
introduce a new API to check if blk is attached
block: make bdrv_put_ref_bh_schedule() as a public API
Backup: clear all bitmap when doing block checkpoint
allow writing to the backing file
Allow creating backup jobs when opening BDS
block: Allow references for backing files
docs: block replication's description
Add new block driver interfaces to control block replication
skip nbd_target when starting block replication
quorum: implement block driver interfaces for block replication
Implement new driver for block replication
Add a new API to start/stop replication, do checkpoint to all BDSes
