Hi Stephen,
Thanks for the response.
I've tried with two virtual NICs, each bound to VFIO, as you can see
below.
verghis@verghis-VirtualBox:~/dpdk-stable-22.11.1/build$
../usertools/dpdk-devbind.py --status

I'm not sure I understand what you mean by 'is the virtual NIC in
VirtualBox the same as virtio. The
NICs are PCnet32 LANCE, a standard NIC, bound to VFIO. In Linux Mint 21
VFIO is built into the kernel,
not a loadable module.
And yet the basicfwd code cannot find even 1 VFIO port. Very weird.
Any ideas?
Thanks.

You need to create two virtual nic's and bind them to VFIO which<br>
will remove from the kernel driver. Not familiar with VirtualBox config.<br=
>
Is the virtual NIC in Virtual Box is not the same as virtio.<br>
If it depends on the proprietary kernel driver, then<br>
you are unlikely to get DPDK to work in virtual box environment.<br>
