Hi Huawie/Yuanhan, I encounter segfault issue in virtio PMD driver when I run any DPDK application in the VM. The virtio devices should not have been probed in the first place since they are not attached to igb_uio driver (and managed by kernel driver).
Network devices using DPDK-compatible driver ============================================ 0000:00:09.0 'FastLinQ QL45000 Series 25GbE Controller' drv=igb_uio unused= 0000:00:0a.0 'FastLinQ QL45000 Series 25GbE Controller' drv=igb_uio unused= Network devices using kernel driver =================================== 0000:00:03.0 'Virtio network device' if= drv=virtio-pci unused=igb_uio #0 0x00000000004e5392 in vtpci_init (dev=0xb61970, hw=0x7fff76146600) at /home2/hpatil/dpdk/drivers/net/virtio/virtio_pci.c:653 #1 0x00000000004effc4 in eth_virtio_dev_init (eth_dev=0xacb7a0 <rte_eth_devices>) at /home2/hpatil/dpdk/drivers/net/virtio/virtio_ethdev.c:1060 #2 0x00000000004b730f in rte_eth_dev_init () #3 0x00000000004cb940 in pci_probe_all_drivers () #4 0x00000000004cbe88 in rte_eal_pci_probe () #5 0x00000000004c0336 in rte_eal_init () #6 0x00000000004404e2 in main () (gdb) p dev->devargs $1 = (struct rte_devargs *) 0x0 Looks like its a known issue based on a old thread: http://dpdk.org/dev/patchwork/patch/12462/ Do we know a fix now? Thanks, harish
