When I launch l2fwd as indicated in this thread, I get this error: ./examples/l2fwd/build/l2fwd -c 0x1f -n 4 --no-huge --no-pci --vdev=virtio-user0,queue_num=256,rx=1,tx=1,cq=0,path=/run/usvhost -- -p 0x1 EAL: Detected 56 lcore(s) EAL: no driver found for virtio-user0 EAL: failed to initialize virtio-user0 device PANIC in rte_eal_init(): Cannot init pmd devices 6: [./examples/l2fwd/build/l2fwd(_start+0x29) [0x429369]] 5: [/lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xf0) [0x7f7b2e003830]] 4: [./examples/l2fwd/build/l2fwd(main+0x2e) [0x4283be]] 3: [./examples/l2fwd/build/l2fwd(rte_eal_init+0xed2) [0x45c042]] 2: [./examples/l2fwd/build/l2fwd(__rte_panic+0xc9) [0x424858]] 1: [./examples/l2fwd/build/l2fwd(rte_dump_stack+0x2b) [0x4635bb]] Aborted (core dumped) I built the driver in dpdk-16.07/drivers/net/virtio path but EAL is unable to find it. Please advise how to use this example with virtio-user device. Thanks, Sandeep
