Standard Virtio - Backed with Vhost Support

Unmodified guests can use Linux networking and virtio drivers. This provides a mechanism to bring existing applications into the production environment immediately.

For virtio interfaces, supports vhost-user transparently by default. This allows QEMU and AVS to share virtio queues through shared memory, resulting in improved performance over standard virtio. The transparent implementation provides a simplified alternative to the open-source kernel and - drivers. For more about these drivers, see Accelerated Virtual Interfaces <accelerated-virtual-interfaces>. The availability of vhost-user also offers additional performance enhancements through optional multi-queue support for virtio interfaces.
