This patchset updates kvm repository with Anthony's virtio implementation along with rx performance improvements and guest reset handling. The original code was sent to qemu devel list 2 weeks ago. It contains support for network & block devices. Using the performance improvement I was able to do 800Mbps for rx/tx. The performance improvement are not implemented in a qemu standard code
