Hmm, there are other contents in this file need to be updated,
for example, we support blockdev-add command for nbd now,
so we can convert the related hmp command to qmp command way.
But since we didn't integrate COLO frame with block replication
and proxy, It is OK to fix them later.
For COLO, the basic capability is still incomplete,
but now we got into 'Soft feature freeze' stage,
I'm wondering if it is possible at this point to combine
COLO frame with proxy and block replication which only needs
three or four patches that only touch colo related files ...
Or uses still can't test COLO feature in qemu 2.8.
Any ideas ? Thanks.

All such patches can go through trivial branch.

I will send some patch about COLO-Proxy combine with COLO-frame in the
future.

I think this patch about COLO architecture,
So, I didn't cc qemu-trivial.
