The change itself looks OK.

I would rather drop the example.  The issue is quite obvious from
description, and fdstreamtest script used for example seems to be a new
test from libvirt not likely to be seen before.

Our README-hacking says that commit message should contain ChangeLog-style
entries for all affected files, and I hope you can add them to your commit
message.

Thanks,
