However you use 2 lcores, and this may imply, that you will be using 2 TX queues, look at the line 2796 in examples/l3fwd/main.c : n_tx_queue = nb_lcores; I had that problem, I fixed it by using just a single lcore, e.g.: -c 0x1 .... --config="(0,0,0),(1,0,0)" On 12.11.2015 18:12, Mario Carrillo wrote: > This is the configuration that I'm using for running the l3fwd example > ./build/l3fwd -c 0x3 -n 1 -d librte_pmd_virtio.so -- -p 0x3 > --config="(0,0,0),(1,0,1)" > > and about environment > Hugepagesize: 2048 kB > > echo 1024 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages > > echo 1024 > > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages > > what do you think? > > Thanks. > Mario. > > > On 11/12/2015 10:48 AM, Arseniy Zaostrovnykh wrote: >> Another possible cause just come to my mind: >> some drivers do not support more than 1 queues in each direction.
