I have an e1000 emulated into the VM which is connected to an emulated vbox interface on the host:
The emulated interface on the host:
The e1000 interface on the VM:
To instantiate the AF_XDP Interface I ran this from bash on the VM:
sudo ip link set dev enp0s8 promisc on up
And from the VPP CLI:
create int af_xdp host-if enp0s8 num-rx-queues all set interface state enp0s8/0 up set int ip address enp0s8/0 192.168.56.101/24
VM specs:
Ubuntu 20.04.1 x64 with VPP

I'm trying to make a basic Virtual Box scenario. The purpose was to test AF_XDP interfaces from VPP basic scenario. Pinging does not work from the host interface to the AF_XDP interface made on top of a emulated e1000.
vpp# ping 192.168.56.1 Statistics: 5 sent, 0 received, 100% packet loss
I tried tracing the AF_XDP interface:
Also, I tried a tcpdump from the host:
arcade@Arcade-PC ~ $ sudo tcpdump -i vboxnet0 -e
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on vboxnet0, link-type EN10MB (Ethernet), capture size 262144 bytes

Worth mentioning: If I do not use AF_XDP, and instead add the e1000 interface as a DPDK device, the ping has no problem in working.
