[dpdk-dev] Need help with the correct steps to run testpmd app on Linux VM using VMXNET3 vNICs
Just an update on the issue I was facing... I got what was wrong in the steps which I followed. I shouldn't have bound the VNICs to igb_uio driver after replacing vmxnet3 driver. The testpdm app worked fine after eliminating that step from the earlier sequence :) Sorry to bother you all.

I am using dpdk v1.7.1 downloaded from dpdk.org. I wish to run testpmd app provided with this release with 2 VMXNET3 vNICs on my setup. My test setup is a 64-bit Ubunutu 14.04 (3.13.0) Linux VM running on a VMWare ESXi-5.5.0 hypervisor on Dell server with Intel Xeon E5-2440. I followed the following stpes to capture the vmxnet3 vNICs in DPDK (all commands run as a root user): cd /home/sandesh/dpdk/dpdk-1.7.1/ export RTE_SDK=/home/sandesh/dpdk/dpdk-1.7.1/ export RTE_TARGET=build modprobe uio insmod build/kmod/igb_uio.ko modprobe vfio-pci mkdir -p /mnt/huge mount -t hugetlbfs nodev /mnt/huge echo 64 > /sys/devices/system/node/node0/hugepages/hugepages-2048kB/nr_hugepages tools/dpdk_nic_bind.py --status Network devices using DPDK-compatible driver Network devices using kernel driver === :02:01.0 '82545EM Gigabit Ethernet Controller (Copper)' if=eth2 drv=e1000 unused=igb_uio,vfio-pci *Active* :03:00.0 'VMXNET3 Ethernet Controller' if=eth0 drv=vmxnet3 unused=igb_uio,vfio-pci *Active* :0b:00.0 'VMXNET3 Ethernet Controller' if=eth1 drv=vmxnet3 unused=igb_uio,vfio-pci *Active* Other network devices = Then I bind VMXNET3 vNICs to igb_uio driver: ../dpdk-1.7.1/tools/dpdk_nic_bind.py --bind=igb_uio eth0 eth1 ../dpdk-1.7.1/tools/dpdk_nic_bind.py --status Network devices using DPDK-compatible driver Network devices using kernel driver === :02:01.0 '82545EM Gigabit Ethernet Controller (Copper)' if=eth2 drv=e1000 unused=igb_uio,vfio-pci *Active* :03:00.0 'VMXNET3 Ethernet Controller' if=eth0 drv=vmxnet3 unused=igb_uio,vfio-pci *Active* :0b:00.0 'VMXNET3 Ethernet Controller' if=eth1 drv=vmxnet3 unused=igb_uio,vfio-pci *Active* Other network devices = Note: I downloaded vmxnet3-usermap extension 1.2 source from dpdk.org to work with VMXNET3.
