You can tell mailman whether you want to receive copies of mails through
the list even when you are listed in cc (defaults to on, but some people
like myself set it off to reduce mail); if you switch that option in
your subscription settings, then you will not see the [Qemu-devel]
prefix on any mail where you were cc'd.  [side note: turning off copies
of mail where you are cc'd triggers what I consider to be a mailman bug:
it actively rewrites the to/cc of the email to omit your address in the
copy it sends to the list, which means people who follow up to the list
no longer cc you, and do not know that you were cc'd in the first place]

Furthermore, there may be other places along the way that do data
de-duplication.  For example, anyone subscribing via a gmail.com address
gets at most one copy of a message based on the message-id; if they are
subscribed to the mailing list and also get a cc of a given message,
only one of those copies will show up (because google suppressed the
second copy with the same message-id, even though the subject lines are
different); the one copy is often (but not always) the one without the
[Qemu-devel] prefix because cc'd mail goes through less processing and
thus tends to arrive sooner than the copy sent through mailman.  [side
note: google calls de-duplication a feature, but you can't turn it off,
and it's one of the reasons that I don't use google for my personal email]
