[dpdk-users] Unable to run l2fwd code

[Sagar Singha]

Hi,

I am using VMXNET3 type VM .OS distro=UBUNTU14.04.
My VM is having only one core CPU and 1 GB RAM

I have followed the below process to configure dpdk after downloading the
source code:

1.make config T=x86_64-native-linuxapp-gcc
2.make
3.sudo modprobe uio
sudo insmod build/kmod/igb_uio.ko
modprobe vfio
modprobe uio_pci_generic
modprobe vfio-pci
4.echo 1024 >
/sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages
5.sudo mkdir /mnt/huge
sudo mount -t hugetlbfs nodev /mnt/huge
6.echo 1 > /sys/module/vfio/parameters/enable_unsafe_noiommu_mode
7../usertools/dpdk_devbind.py --bind=vfio-pci --force ens160


after that I am running the below command for running the l2fwd

l2fwd c1 n4 --no-huge -- -p1

Then the error is like below:

EAL: Detected 1 lcore(s)
