You have to understand that the Ubuntu version qemu-kvm is based on the common qemu software.
If your patch provides modification to the Ubuntu-specific part, you should create a bug report in https://bugs.launchpad.net/ubuntu/+source/qemu-kvm/+filebug or https://bugs.launchpad.net/qemu/+filebug

If your modifcation is an enhancement for the common qemu software, you should post your patch on the related project page
http://wiki.qemu.org respective http://wiki.qemu.org/Contribute/SubmitAPatch
