Hi there,

I commented on the original bug in Launchpad.  We're willing and able
to carry the patch against qemu-kvm in Ubuntu, I just asked that the
reporter at least submit the patch upstream for discussion.  I don't
see where that has happened yet.  It's a trivial patch to submit.
Please note in that bug a pointer to the mailing list thread, if you
start one.

To your specific question, different communities have different
requirements on patch submission, so you do need to consult each
community.  A good place to start might be the
Documentation/SubmittingPatches how-to in the kernel tree:

In this case, I think you're going to want to send your patch to the
qemu-devel (on CC) mailing list (perhaps in addition to sending it
here, to the kvm list).
