The following patchset backports vhost net support from qemu-kvm master to F13. I'd like the patches to be added to fedora before feature freeze.
These patches are required for vhost net feature. Feature page here: https://fedoraproject.org/wiki/Features/VHostNet The patches have been posted upstream, and apply without changes. Most infrastructure is upstream already, and has been backported by simple cherry-pick. Thanks! Michael S.
