[dpdk-users] FATAL: Module uio not found

[RanjithKumar]

Hello All,

modprobe uio did not work , and below is the output VM NIC current drivers.

ubuntu at mysite-vpgwu-slice1-25:~/dpdk-2.0.0/tools$ ./dpdk_nic_bind.py
--status

Network devices using DPDK-compatible driver
============================================
<none>

Network devices using kernel driver
===================================
0000:00:03.0 'Virtio network device' if= drv=virtio-pci unused=
0000:00:04.0 'Virtio network device' if= drv=virtio-pci unused=
0000:00:05.0 'Virtio network device' if= drv=virtio-pci unused=
0000:00:06.0 'Virtio network device' if= drv=virtio-pci unused=
0000:00:07.0 'Virtio network device' if= drv=virtio-pci unused=

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

So i followed below steps to use virtio-pci


   1. modprobe vfio enable_unsafe_noiommu_mode=1
   2. modprobe vfio-pci
   3. ./dpdk_nic_bind.py -b vfio-pci 0000:00:04.0

But i am getting below error while binding the Virtio NIC to DPDK

*Error: bind failed for 0000:00:04.0 - Cannot bind to driver vfio-pci
Error: unbind failed for 0000:00:04.0 - Cannot open
/sys/bus/pci/drivers//unbind*

*Any input?*

*Regards,*
*Ranjith*



Regards,
Ranjith
