Reason/location: PMD: rte_eth_dev_configure: ethdev port_id=3D1 nb_rx_queues= =3D8 > 2 EAL: Error - exiting with code: 1 System info: DPDK version: 2.0 NIC: 82599EB, sr-iov enabled. SR-IOV config at ESXi 5.5 hypervisor host: max_vfs=3D2 Guest OS: Linux OS based. Driver: ixgbevf.ko VM is configured with 3 vCPUs. Before linking the port to DPDK, I see that= , pci device (VF) comes up with 8 rx/tx queues (using native kernel driver = ixgbevf.ko, /sys/class/net/ethx/queues/*). But DPDK code expect max queues= for device to be '2' and hence the crash. Am I missing anything here? A= ppreciate for any suggestions/fixes for the issue. Thanks, -Vithal
