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.
