You also need to describe how the parameters work in the text below.
7:08 p.m.
It is better to format the patch summary like this format: "SUBSYSTEM:
TITLE"
For example, this patch could be "virsh: Added a few attach-disk parameters"
You can see the git log of libvirt for more reference:

We prefer one declaration per line with explicit type. Prior art here is
wrong, but there's no need to fix it. Just add your variables on
separate lines.

So, --source-name is mutually exclusive with --source. Please record
this using VSH_EXCLUSIVE_OPTIONS_VAR as we do for other arguments.
--source-name also requires --source-protocol, which also should be
recorded.

You must not modify pointers you get from vshCommandOptStringReq. Copy
the string if you need to modify it.

Note that the result of the above will be an ugly formatted XML, but we
strive for it to look correct. You'll need to use virBufferAdjustIndent
and use only one newline per formatting API since only the last newline
in a formating API use (virBufferAsprintf and such) triggers automatic
indentation.
