Hi all, Please ignore the previous one, this is the updated patch.
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.
