[dpdk-dev] basic forwarding example not working
I am using two virtio network adapter on VM on KVM host. As in following output, I have bound both interface with igb_uio driver ./dpdk_nic_bind.py --bind=igb_uio 00:0a.0 ./dpdk_nic_bind.py --bind=igb_uio 00:0b.0 [root at localhost tools]# ./dpdk_nic_bind.py --status Network devices using DPDK-compatible driver :00:0a.0 'Virtio network device' drv=igb_uio unused= :00:0b.0 'Virtio network device' drv=igb_uio unused= Network devices using kernel driver === :00:03.0 'RTL-8100/8101L/8139 PCI Fast Ethernet Adapter' if=ens3 drv=8139cp unused=igb_uio *Active* :00:08.0 'Virtio network device' if= drv=virtio-pci unused=igb_uio :00:09.0 'Virtio network device' if= drv=virtio-pci unused=igb_uio Other network devices = But when I run basic fowarding example from skeleton, I get following error ./basicfwd -c 1 -n 2 EAL: Detected lcore 0 as core 0 on socket 0 EAL: Support maximum 128 logical core(s) by configuration.

Hi, for virtio-pci devices you should either just unbind them or bind them to one of the generic drivers like uio_pci_generic. At least I never saw igb_uio on virtio-pci devices. There might be more complete answers, but I think that should get you going.

Hi, I think your log is cut short. At least in what you posted I don't see the "card skipped" issue anymore. Also I don't see the segfault at the end anymore. Actually there is no error left in this second log. I never used basicfwd so far - maybe it is something special to it that breaks your case. If it follows the normal EAL commandline I'd recommend to also add something for memory like --socket-mem 2048. Well without it should just try to grab everything, but I prefer to specify things. Could you try to run the testpmd or l2fwd programs instead - IMHO these are more commonly used (=usually work better).
