Hmm... I think setting defaults should be pushed into libxl.
But I think this is issue is orthogonal to this patch, and we can
revisit this later.

"Option -p must be used in conjunction with -c".
And please use fprintf(stderr,...) here because libxl_defbool_val
doesn't touch errno.

I don't claim I know much about COLO though, nor have I ever run it, so
it would be better to have a second eye on this patch.
There are some style nits below.

There is only one statement so no need to have {}.
You can move the comment before "if" and remove {}.
Same rule applies to all the patches.

I think I'm going to ask for a bit of cleanup here.
You don't actually need the values of colo_proxy_script and
userspace_colo_proxy here.
So instead of having both values here. I suggest:
1. provide a patch to refactor existing code so that do_domain_create
doesn't take colo_proxy_script anymore. It should be able to do
cdcs->dcs.colo_proxy_script = params->colo_proxy_script.
2. rework this patch on top of that patch.
Does this make sense? Let me know if this is not feasible due to I miss
something obvious.

I suppose you can use LIBXL_HAVE_COLO_USERSPACE_PROXY for this whole
series.
Since this series touches a lot of common code, I would like you to
confirm you've tested configurations without COLO enabled. Basic VM
lifecycle operations like create, save/restore and migration should
still work.
Wei.

If I understand correctly, we use LIBXL_HAVE_COLO_USERSPACE_PROXY for
this whole series means we make colo userspace proxy as default option,
User can't use colo kernel proxy by a easy way (remus commands).
The goal of this series is to provide a another way to run colo proxy(we
recommended),
We want to keep the colo kernel proxy function currently(maybe someone can
maintain it), and when colo userspace proxy performance better than
kernel proxy,
we will change colo userspace as default option.

No, that macro is not used to denote which mechanism is the default one.
It is used to indicate the availability of a particular thing in libxl.
So you can have that macro and choose whichever you want to be the
default.
Feel free to ask questions if I'm not clear enough.
Wei.

OK. I will add the macro "LIBXL_HAVE_COLO_USERSPACE_PROXY"
like the "LIBXL_HAVE_REMUS".
Thank you for your nice comments.

We use old kernel colo proxy way to get the checkpoint event from qemu.
This patch have some TODO job.
Qemu compare need add a API to support this(I will add this in qemu).

No major objection but this patch probably needs reworking if you change
your previous patches.
