[dpdk-users] SRIOV with DPDK-PF: PMD: eth_ixgbevf_dev_init(): VF Initialization Failure
Hi all, I want to use both PF and VF bound to igb_uio. However, when doing so, VF init fails: EAL: PCI device :04:10.1 on NUMA socket 0 EAL: probe driver: 8086:10ed rte_ixgbevf_pmd PMD: eth_ixgbevf_dev_init(): VF Initialization Failure: -100 EAL: Error - exiting with code: 1 Cause: Requested device :04:10.1 cannot be used The sequence I use it this: Initial state: - 04:00.1 is bound to Linux driver (ixgbe) - no VFs configured Step 1: configure a VF echo 1 > /sys/bus/pci/devices/:04:00.1/sriov_numvfs Step 2: set VF's MAC address ip link set dev enp4s0f1 vf 0 mac 00:bb:dd:04:00:00 Step 3: bind the VF to igb_uio Step 4: execute L2FWD ./dpdk/examples/l2fwd/build/l2fwd -c 1 -n 1 -w :04:00.1 -- -T 0 -p 1 Works as expected Step 5: bind the PF to igb_uio Step 6: execute L2FWD again ./dpdk/examples/l2fwd/build/l2fwd -c 1 -n 1 -w :04:00.1 -- -T 0 -p 1 --- FAILURE --- I tried several DPDK versions (1.7.1, 2.0.0, 2.2.0, 16.07).
