Sorry, I'm still hitting an issue where I cannot create the interface in VPP:
vpp# create interface avf 0000:13:00.0 create interface avf: device not bound to 'vfio-pci' or 'uio_pci_generic' kernel module So I tried to bind the NIC to vfio-pci: root@test:~# modprobe vfio-pci root@test:~# /usr/local/vpp/vpp-config/scripts/dpdk-devbind.py -s Network devices using DPDK-compatible driver ============================================ <none> Network devices using kernel driver =================================== 0000:13:00.0 'Ethernet Virtual Function 700 Series' if=ens224 drv=i40evf unused= root@test:~# /usr/local/vpp/vpp-config/scripts/dpdk-devbind.py --bind vfio-pci 13:00.0 Error - no supported modules(DPDK driver) are loaded Thoughts?
