[dpdk-users] dpdk-users] : unable to run the applications due to PMD failure

[amartya.das]

Hi,

I am using the OVS-DPDK at the host machine and creating a couple of virtual ports to connect to my VM. (OVS 2.6.1 and DPDK 16.07)

In the VM I am binding one of the ports to DPDK (16.04)
./tools/dpdk_nic_bind.py --status

Network devices using DPDK-compatible driver
============================================
0000:00:03.0 'Virtio network device' drv=igb_uio unused=virtio_pci

Network devices using kernel driver
===================================
0000:00:02.0 'Virtio network device' if= drv=virtio-pci unused=virtio_pci,igb_uio

Other network devices
=====================
<none>

Now I am running the sample applications and getting the error for PMD driver and getting a core-dump.

Is vfio_pci module loaded ? If not, try modprobe vfio_pci.

Thanks,
