This changes default output of an existing command, but it's not the
first time we've done that (for example, commit aa2c9726 added the
"Security model" string). For this particular command, that's fine,
since it remains machine parsable (each line is a name-value pair, and
you search for the line with the name you care about); still, I'd feel
better if your new string came last rather than in the middle in case
existing parsers count a certain number of lines and expect a particular
name on that line.
Agree it's better as a last string, but it's need changes on codes to
print "Security *" strings, to prevent the early return.
I'm inclined to keep this patch unchanged, as for the "security" strings,
there will be no strings printed out if virNodeGetSecurityModel is not
supported. So it still may break the script which parse a certain number
of lines.
And if we print "security" strings regardless of whether is supported or
not, success or failure, (just like "persistent", "autostart" do), it might
break the scripts too.
