How to prepare the COLO test environment

How to prepare the COLO test environment

[-- Attachment #1.1: Type: text/plain, Size: 499 bytes --]

Hello,

I am looking for ways to try out COLO.
I tried a wiki and mailing list, but I failed.
I do not know whether the wiki and the mailing list are correct.
Could you tell me the latest way to try it?

I have read the following documents:

COLO - Coarse Grain Lock Stepping
https://wiki.xen.org/wiki/COLO_-_Coarse_Grain_Lock_Stepping

Mailing list
https://lists.xen.org/archives/html/xen-devel/2016-03/msg00376.html

If there are some mistakes in English, I'd like apologize.
Thank you.

Yamamoto

Unfortunately, wiki and the mail can't be updated. Latest COLO use user
space COLO-Proxy in qemu,
Wiki just guide you to setup kernel space COLO-Proxy(this version
COLO-proxy not being maintained).
For some reason, Xen COLO need use some KVM COLO codes, but we haven't push
all qemu code
to upstream, just in progress.
So, you can try our internal latest version:
Xen:
https://github.com/zhangckid/xen/tree/xen-colo-v2
Qemu:
https://github.com/zhangckid/qemu/tree/qemu-colo-for-xen

The start scripts is same with wiki (you just need remove the modprobe
commands).
Thank you for the question, I will update Xen wiki this week.

Thanks
Zhang Chen

I'm not sure what you mean with "wiki...can't be updated". If you're
saying that neither you nor anyone that you know have the time or the
knowledge to update it, then fine.

But, technically, the Wiki can be updated and, if possible, it should
be.

Regards,
Dario

Yes, I means we forgot to update COLO wiki.

Hi, Yamamoto.

The Xen COLO wiki has been updated, you can try it.
https://wiki.xen.org/wiki/COLO_-_Coarse_Grain_Lock_Stepping

Because the COLO proxy module and the block replication module share with
KVM COLO,
you can read related part from KVM COLO wiki maybe easier to understand
COLO.
Some detail you can get from here.
https://wiki.qemu.org/Features/COLO

Thanks
Zhang Chen
