Hi All, I'm a newbie to openvswitch and I followed the below link to install ovs with DPDK on RHEL7 machine.
[root@artha ~]# uname -a Linux BL4 3.10.0-123.el7.x86_64 #1 SMP Mon May 5 11:16:57 EDT 2014 x86_64 x86_64 x86_64 GNU/Linux https://github.com/openvswitch/ovs/blob/master/INSTALL.DPDK.md When I ran vswitch daemon, it reports following error [I binded igb_uio to the i350 NIC]. 2015-06-22T18:04:38Z|00003|dpdk|ERR|No Ethernet devices found. Try assigning ports to UIO. 2015-06-22T18:04:38Z|00004|dpdk|INFO|Ethernet Device Count: 0 Following PCI bind status. [root@artha ~]# ./dpdk-1.7.1/tools/dpdk_nic_bind.py --status Network devices using DPDK-compatible driver ============================================ 0000:0a:00.0 'I350 Gigabit Network Connection' drv=igb_uio unused= Network devices using kernel driver =================================== 0000:03:00.0 'NetXtreme BCM5719 Gigabit Ethernet PCIe' if=eno1 drv=tg3 unused= 0000:03:00.1 'NetXtreme BCM5719 Gigabit Ethernet PCIe' if=eno2 drv=tg3 unused= 0000:03:00.2 'NetXtreme BCM5719 Gigabit Ethernet PCIe' if=eno3 drv=tg3 unused= 0000:03:00.3 'NetXtreme BCM5719 Gigabit Ethernet PCIe' if=eno4 drv=tg3 unused= 0000:0a:00.1 'I350 Gigabit Network Connection' if=ens3f1 drv=igb unused= Other network devices ===================== <none> Then I created I ovs bridge using below cmd: ./ovs-vsctl --no-wait add-br ovs -- set Bridge ovs datapath_type=netdev ./ovs-vsctl add-port ovs dpdk0 -- set Interface dpdk0 type=dpdk When I add dpdk port it reports, "could not open network device dpdk0 (Unknown error -19)" Please let me know 1. What could be possible reason for not detecting the interface which is binded to igb_uio? 2. How to add the port which is binded to igb_uio here? Thanks in advance. Regards, Varun
