Subject: [Qemu-devel] [PATCH 0/2] PoC: Block replication for continuous checkpointing
Date: Thu, 25 Dec 2014 17:39:17 +0800	[thread overview]
Message-ID: <1419500359-9190-1-git-send-email-yanghy@cn.fujitsu.com> (raw)

Hi all,

We are implementing COLO feature for QEMU.
For what COLO is and steps to setup and runing COLO, refer to:
http://wiki.qemu.org/Features/COLO
  * you can get almost everything about COLO from that Wiki page.
Previously posted RFC proposal:
http://lists.nongnu.org/archive/html/qemu-devel/2014-06/msg05567.html
Latest COLO code:
https://github.com/macrosheep/qemu (checkout the latest COLO branch)

Our current work is implementing COLO Disk manager, we are planning to
implement it as a block driver which called 'blkcolo'. But we need the
feedbacks from commiunity.

This patchset is a Proof of Concept of our Block replication design,
including:
  1. A document 'docs/blkcolo.txt' which describes the drift design
     specification.
  2. Some DEMO/POC code that will help you to understand how we are
     going to implement it.

Please feel free to comment.
We want comments/feedbacks as many as possiable please, thanks in advance.

Thanks,
Yang.
