The network PV driver that was initiated by Ingo Molnar is developed by Yan Vugenfirer and me. It is not yet stable/clean for main stream although can be checked out from a private git repo. Using direct irq injection it can reach multi-gigabit throughput. Using signals sent to qemu (to sync with APIC's tpr) it does only ~500Mbps. When the APIC/PIC will reside in the kernel we can pass to direct mode only. Expect to publish the driver in the May. Arjan van de Ven from RedHat is working on pv block device.
