However, when running on FreeBSD, the EAL failed with error message as below: EAL: failed to parse device "vdev:virtio_user0" EAL: Failed to attach device on primary process Then I tried with the tap dev but it also failed: EAL: failed to parse device "vdev:net_tap0" EAL: Failed to attach device on primary process Is there a way to send/receive packet to the kernel on FreeBSD? Please help. Thank you very much.
