Para-virtualization is the leading approach in IO device virtualization. It allows the hypervisor to interpose on and inspect a virtual machine's I/O traffic at run-time. Examples of such interfaces are KVM's virtio [6] and VMWare's VMXNET [7]. Current implementations of virtual I/O in the hypervisor have been shown to have performance and scalability limitations [2, 3, 5].
