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: * http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob_plain;f=Documentation/SubmittingPatches;hb=HEAD 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). :-Dustin -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
