dpdk-ans not work in virtual machine about dpdk-ans HOT 11 CLOSED

Please share the startup log.

You may add some debug log in ans_main.c to check if receive packets from the NIC.

You may capture packets on another VM or add some debugs in ans_main.c to check it.

Hi,

i add printf just after ans_packet_handle_call end print ret code value

Perhaps il will try to ping 10.0.0.2 ...

from dpdk-ans.

it's work sorry for that

what do you think about the modif i made in the source ?

in particular
ret = rte_eth_tx_queue_setup(portid, queueid, ANS_TX_DESC_DEFAULT, socketid, txconf);
with
ret = rte_eth_tx_queue_setup(portid, queueid, ANS_TX_DESC_DEFAULT, rte_eth_dev_socket_id(portid), NULL);

Now i have a core dumped when start dpdk-iper3

1. Shall configure different parameters for different NIC.
2. For the coredump, you shall start ANS before start dpdk-iperf.

Thanks again
