Hi team,

I am trying to run dpdk-testpmd utility, but I am not able to make it work even though I have already used dpdk-devbind.py utility. I haven't been able to find the solution yet, could you please help me?

I get the following output while executing ./usertools/dpdk-devbind.py -s:

Network devices using kernel driver
===================================
0000:04:00.0 'RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller 8168' if=enp4s0 drv=r8169 unused=vfio-pci *Active*

No 'Baseband' devices detected
==============================

No 'Crypto' devices detected
============================

No 'DMA' devices detected
=========================

No 'Eventdev' devices detected
==============================

No 'Mempool' devices detected
=============================

No 'Compress' devices detected
==============================

No 'Misc (rawdev)' devices detected
===================================

No 'Regex' devices detected
===========================

No 'ML' devices detected
========================






In the same way, this is the output I get when I execute sudo dpdk-testpmd -l 0-3 -n 4 -- -i --portmask=0x1 --nb-cores=2:

EAL: Detected CPU lcores: 12
EAL: Detected NUMA nodes: 1
EAL: Detected static linkage of DPDK

testpmd: preferred mempool ops selected: ring_mp_mc
EAL: Error - exiting with code: 1
  Cause: Creation of mbuf pool for socket 0 failed: Cannot allocate memory


Thanks in advance
