Hi, While running the DPDK KNI sample application, we are facing packet drop after some time.
*Setup:-* 1. 2 VMs configured using Ubuntu 14.04 2. eth0 of both VMs connected to each other, and able to ping *DPDK related setup:-* 1. 1st VM eth0 is bound with DPDK driver[bind=uio_pci_generic] 2. Insert the KNI module in Linux kernel[insmod rte_kni.ko]. 3. Start the KNI application [*./build/kni -c 0x3 -n 4 -- -P -p 0x1 --config="(0,0,1)"*]. 4. Assign the ip address to vEth0 [*ifconfig vEth0 10.0.1.2*] 5. start the tcpdump on vEth0 6. From 2nd VM try to ping 8.8.8.8 *Issue:- * ping works fine for around 400-500 packets(we reserved 2000 2MB hugepages). after that ping packet is never sent back to VM2 on further investigation we found *rte_eth_tx_burst *always returns 0 when the problem occurs we are investigating it further, But before that any help is welcome on the side note, we have another issue with log levels, to investigate the above issue we were trying to enable the logs for PMD using the following code rte_set_log_type(RTE_LOGTYPE_PMD, 1); rte_set_log_level(RTE_LOG_DEBUG); during initialization we see some logs from PMD, But after that no logs during receive and transmission of packets, any idea why is that? Thanks Amit Sharma
