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.
