Hi,
we are trying to run two instances of pktgen-dpdk on the same host, each
one working on one network interface
we use the following commands to run pktgen:
sudo -E ./app/x86_64-native-linuxapp-gcc/pktgen -l 0-4 -n 3
--file-prefix pg1 -b 06:00.1 -- -P -m "1.0"
sudo -E ./app/x86_64-native-linuxapp-gcc/pktgen -l 5-8 -n 3
--file-prefix pg0 -b 06:00.0 -- -P -m "1.0"
each one is working separately, but if we run the second one when the
first one is running (or vice-versa), we receive this error :
Create: Default TX 0:0 - Memory used (MBUFs 16384 x (size 2176 +
Hdr 128)) + 192 = 36865 KB, headroom 128
!PANIC!: Cannot create mbuf pool (Default TX 0:0) port 0, queue 0,
nb_mbufs 16384, socket_id 0: No such file or directory
PANIC in pktgen_mbuf_pool_create():

we are using
-- Pktgen Ver: 3.5.1 (DPDK 18.08.0-rc0) Powered by DPDK
** Version: DPDK 18.08.0-rc0, Command Line Interface with timers
are we doing something wrong?
