The vhost sample application demonstrates integration of the Intel(R) Data Plane Development Kit (Intel(R) DPDK) with the Linux KVM hypervisor by implementing the vhost-net offload API. The sample application performs simple packet switching between virtual machines based on Media Access Control (MAC) address or Virtual Local Area Network (VLAN) tag. The splitting of ethernet traffic from an external switch is performed in hardware by the Virtual Machine Device Queues (VMDQ) and Data Center Bridging (DCB) features of the Intel(R) 82599 10 Gigabit Ethernet Controller.
