I am using openvswitch in userspace. Below are my setup:
Ubuntu 16.04.5 LTS Openswitch-2.5.5 Namespace h1 - Host 1 Namespace h2 - Host 2 Created bridge s1 with option datapath_tye=netdev Added ports eth1 and eth2 to the bridge I can ping between h1 and h2. I can see the flows being installed on the flow table. But when I use iperf it does not connect between h1 and h2. I noticed the following in ovs-vswitchd.log. 2018-08-10T19:38:23.084Z|00243|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:23.308Z|00244|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:23.404Z|00245|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:23.468Z|00246|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:24.108Z|00247|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:24.108Z|00248|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:24.492Z|00249|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:24.492Z|00250|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:24.620Z|00251|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:25.484Z|00252|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:28.460Z|00253|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:28.972Z|00254|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:32.720Z|00255|connmgr|INFO|s1<->tcp:127.0.0.1:6653: 1 flow_mods 10 s ago (1 adds) 2018-08-10T19:38:37.420Z|00256|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:37.676Z|00257|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:39.279Z|00258|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:53.805Z|00259|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:38:54.573Z|00260|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:39:27.341Z|00261|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:39:29.389Z|00262|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:39:32.720Z|00263|connmgr|INFO|s1<->tcp:127.0.0.1:6653: 6 flow_mods in the 14 s starting 53 s ago (6 adds) 2018-08-10T19:40:36.972Z|00264|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:40:36.972Z|00265|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:40:47.447Z|00266|connmgr|INFO|s1<->tcp:127.0.0.1:6653: 5 flow_mods in the 6 s starting 10 s ago (5 adds) 2018-08-10T19:41:47.448Z|00267|connmgr|INFO|s1<->tcp:127.0.0.1:6653: 1 flow_mods 54 s ago (1 adds) 2018-08-10T19:43:08.524Z|00268|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:43:08.524Z|00269|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:47:47.052Z|00270|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error 2018-08-10T19:47:47.052Z|00271|netdev_linux|WARN|error sending Ethernet packet on s1: Input/output error _______________________________________________ dev mailing list [email protected] https://mail.openvswitch.org/mailman/listinfo/ovs-dev
