i run virtualbox 6.0 on macos 10.14.6 guest os is ubuntu 16.04.

guest network device is set Paravirtualized network adapter (virtio-net), as documented in https://www.virtualbox.org/manual/ch06.html

when i run app: /home/zzlu/Downloads/uio_test/ixy/cmake-build-debug-remote/ixy-pktgen 0000:00:03.0 [DEBUG] /home/zzlu/Downloads/uio_test/ixy/src/pci.c:58 pci_open_resource(): Opening PCI resource at /sys/bus/pci/devices/0000:00:03.0/config [DEBUG] /home/zzlu/Downloads/uio_test/ixy/src/pci.c:58 pci_open_resource(): Opening PCI resource at /sys/bus/pci/devices/0000:00:03.0/config [INFO ] /home/zzlu/Downloads/uio_test/ixy/src/driver/virtio.c:352 virtio_init(): Detected virtio legacy network card [DEBUG] /home/zzlu/Downloads/uio_test/ixy/src/pci.c:58 pci_open_resource(): Opening PCI resource at /sys/bus/pci/devices/0000:00:03.0/resource0 [DEBUG] /home/zzlu/Downloads/uio_test/ixy/src/driver/virtio.c:275 virtio_legacy_init(): Configuring bar0 [DEBUG] /home/zzlu/Downloads/uio_test/ixy/src/driver/virtio.c:284 virtio_legacy_init(): Host features: 410fdda3 [ERROR] /home/zzlu/Downloads/uio_test/ixy/src/driver/virtio.c:289 virtio_legacy_init(): Device does not support required features

i can figure out this error in code, my host feature without VIRTIO_F_ANY_LAYOUT how can i fix this?

You need the branch virtualbox-workarounds, see https://github.com/emmericp/ixy/commit/ea22597d2ea78a8c4cc3cd30305573d381a9303e
