Give 1 core for vhost and virtio respectively.\n+About vswitch sample, a new option --total-num-mbufs is added from dpdk-22.03,\n+for the user to set larger mbuf pool to avoid launch fail. For example, dpdk-vhost \n+will fail to launch with a 40G i40e port without setting larger mbuf pool.\n+For more about vhost switch sample, please refer to the dpdk docs:\t\n+http://doc.dpdk.org/guides/sample_app_ug/vhost.html\n+For virtio-user vdev parameter, you can refer to the dpdk doc:\n+https://doc.dpdk.org/guides/nics/virtio.html#virtio-paths-selection-and-usage.\n+\n+Prerequisites\n+=============\n+\n+Topology\n+--------\n+\n+Test flow: TG-->nic-->vswitch-->virtio-user-->vswitch-->nic-->TG\n+\n+Hardware\n+--------\n+Supportted NICs: all except columbiaville that not support VMDQ\n+\n+Software\n+--------\n+Trex:http://trex-tgn.cisco.com/trex/release/v2.26.tar.gz\n+\n+General set up\n+--------------\n+1.
