This patchset updates kvm repository with Rusty's/Anthony's virtio implementation along with already sent tx performance bug fix and new module reload fixes. The first 9 patches are Rusty's and Anthony's work and are pending in Rusty's tree. This code together with the userspace patches able to do 800Mbps for network rx/tx. Enjoy [with the courtesy of Anthony & Rusty],

This is a first go at adding support for the modern (based on the 1.0 virtio spec) virtio-pci implementation. kvmtool makes it simple to add additional transports such as this because of it's layering, so we are able to add it as a 3rd (after legacy virtio-pci and virtio-mmio) transport layer, and still allow users to choose to use either the legacy or the modern implementations (but setting
