In this example, the control network 00:03.0, remains unbound to UIO driver but remains attached to Linux device driver (ssh access with putty) and just the target interfaces are bound. Below, it shows all 3 interfaces bound to the uio driver, which are not usable until a task uses the UIO driver.

On the VM : I am able to see two interfaces . and working fine with traffic in rawsocket mode . my problem is when i bind the interfaces to pmd driver[ ibg_uio ] my virtual machine is getting hanged . and i am not able to access it further . now my question is . what may be the reason for the behavior . and how can in debug the root cause . please help in finding out the problem . ./tools/dpdk_nic_bind.py --status Network devices using DPDK-compatible driver ============================================ <none> Network devices using kernel driver =================================== 0000:00:03.0 '82540EM Gigabit Ethernet Controller' if=ens3 drv=e1000 unused=igb_uio *Active* 0000:00:04.0 'Virtio network device' if= drv=virtio-pci unused=igb_uio 0000:00:05.0 'Virtio network device' if= drv=virtio-pci unused=igb_uio Other network devices ===================== <none> ./dpdk_nic_bind.py --bind=igb_uio 00:04.0 00:05.0 ./x86_64-softmmu/qemu-system-x86_64 -cpu host -boot c -hda /home/utils/images/vm1.img -m 2048M -smp 3 --enable-kvm -name 'VM1' -nographic -vnc :1 -pidfile /tmp/vm1.pid -drive file=fat:rw:/tmp/qemu_share,snapshot=off -monitor unix:/tmp/vm1monitor,server,nowait -net none -no-reboot -mem-path /dev/hugepages -mem-prealloc -netdev type=tap,id=net1,script=no,downscript=no,ifname=usvhost1,vhost=on -device virtio-net-pci,netdev=net1,mac=00:16:3e:00:03:03,csum=off,gso=off,guest_tso4=off,guest_tso6=off,guest_ecn=off -netdev type=tap,id=net2,script=no,downscript=no,ifname=usvhost2,vhost=on -device virtio-net-pci,netdev=net2,mac=00:16:3e:00:03:04,csum=off,gso=off,guest_tso4=off,guest_tso6=off,guest_ecn=off ---------- thanks srinivas. _______________________________________________ Dpdk-ovs mailing list Dpdk-ovs at lists.01.org https://lists.01.org/mailman/listinfo/dpdk-ovs
