[dpdk-users] PMD: eth_ixgbevf_dev_init(): VF Initialization Failure: -15

[Sandeep Rayapudi]

Hi all, when i tried to run pktgen/testpmd on the container with SR-IOV VF,
VF Init fails with error code -15. Any inputs please?

Steps I followed are:

1.       Create a Virtual Function on NIC

a.       Add boot option for the host: *iommu=pt intel_iommu=on*

b.      Without this option, we're unable to edit the file:
/sys/bus/pci/devices/0000:05:00.0/sriov_numvfs

c.       After reboot, echo *1* > sriov_numvfs

d.      Now, we're able to see *1 *Virtual Function in *lspci | grep -i
ethernet* output

e.      Now dpdk-devbind tool displays that the virtual function bound to
*ixgbevf*

2.       Bind the VF NIC to vfio-pci

3.       Create the mountpoint

4.       Start the container with:

a.       docker run --privileged -itd -v */dev/vfio/vfio0:/dev/vfio/vfio0*
-v /mnt/huge_c0/:/dev/hugepages/ -v
/sys/bus/pci/drivers:/sys/bus/pci/drivers -v
/sys/kernel/mm/hugepages:/sys/kernel/mm/hugepages -v
/sys/devices/system/node:/sys/devices/system/node -v /dev:/dev -v /usr:/usr
-v /lib:/lib

5.       Start DPDK application

./app/app/x86_64-native-linuxapp-gcc/pktgen -c 0x1f -n 3 -- -P -m "2.0"
