The topology is given below Physical port eth1 is bound to DPDK using tools/setup.sh. We did loaded Igb_uio module, allocated hugepages etc. *DPDK port 0* ^ | | --------------------------- *Physical port(eth1)* ~~~~~~ * vEth0* | | | *eth10(different machine connected back-to-back)* We loaded KNI module and ran the KNI applicaiton with the following command *kni -c 0xff -n 4 -- -p 0x1 -P --config="(0,4,6)"* and we could see vEth0 added in kernel. 1. Now, How can we test traffic with the KNI interface to external world. ?? We were not able to ping between *vEth0* and *eth10*. 2. We launched a KVM guest machine, and provided *vEth0* as the tap interface. When we initiated ping to *eth10* from the guest, we can see the arp requests on* vEth0 (saw in tcpdump)*. But these packets are not reaching *eth10. * If we ping from *eth10*, we dont see any packets on *vEth0*. Do we need to do any other configuration other than this? Any help is much appreciated. -- Thanks & Regards, Venkateswara Rao Dokku
