Hi All, OVS is not able to connect to any controllers(opendaylight n floodlight). I am seeing following messages in ovs-vswitchd.log.
I have checked all baisc settings of iptables, firewalld etc etc. On controller machine netstate -an shows the "tcp 0.0.0.0:6633" in listen mode. Anyone has faced this before? ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 2015-06-05T08:24:07.575Z|00001|vlog|INFO|opened log file /root/ovs230build/ovs-vswitchd.log 2015-06-05T08:24:07.577Z|00002|reconnect|INFO|unix:/root/ovs230build/var/run/openvswitch/db.sock: connecting... 2015-06-05T08:24:07.577Z|00003|reconnect|INFO|unix:/root/ovs230build/var/run/openvswitch/db.sock: connected 2015-06-05T08:24:07.578Z|00004|bridge|INFO|ovs-vswitchd (Open vSwitch) 2.3.0 2015-06-05T08:24:07.597Z|00005|ofproto_dpif|INFO|system@ovs-system: Datapath supports recirculation 2015-06-05T08:24:07.597Z|00006|dpif|WARN|system@ovs-system: execute userspace(pid=0,userdata(00000000)) failed (Invalid argument) on packet metadata=0,in_port=0,vlan_tci=0x0000,dl_src=00:00:00:00:00:00,dl_dst=00:00:00:00:00:00,dl_type=0x1234 2015-06-05T08:24:07.597Z|00007|ofproto_dpif|WARN|system@ovs-system: variable-length userdata feature probe failed (Invalid argument) 2015-06-05T08:24:07.617Z|00008|dpif|WARN|system@ovs-system: failed to put[create] (Invalid argument) skb_priority(0),skb_mark(0),in_port(0),eth(src=00:00:00:00:00:00,dst=00:00:00:00:00:00),eth_type(0x8847),mpls(label=0,tc=0,ttl=0,bos=1) 2015-06-05T08:24:07.617Z|00009|ofproto_dpif|INFO|system@ovs-system: MPLS label stack length probed as 0 2015-06-05T08:24:07.636Z|00010|bridge|INFO|bridge switch1: added interface switch1 on port 65534 2015-06-05T08:24:07.636Z|00011|bridge|INFO|bridge switch1: using datapath ID 0000927a4306964b 2015-06-05T08:24:07.636Z|00012|connmgr|INFO|switch1: added service controller "punix:/root/ovs230build/var/run/openvswitch/switch1.mgmt" 2015-06-05T08:24:07.641Z|00013|connmgr|INFO|switch1: re-added service controller "punix:/root/ovs230build/var/run/openvswitch/switch1.mgmt" 2015-06-05T08:24:07.647Z|00014|bridge|INFO|bridge switch1: using datapath ID 0000000000000001 2015-06-05T08:24:07.650Z|00015|connmgr|INFO|switch1: added primary controller "tcp:172.16.51.1::6633" 2015-06-05T08:24:07.651Z|00016|rconn|INFO|switch1<->tcp:172.16.51.1::6633: connecting... 2015-06-05T08:24:07.651Z|00017|rconn|WARN|switch1<->tcp:172.16.51.1::6633: connection dropped (Connection refused) 2015-06-05T08:24:07.665Z|00018|bridge|INFO|bridge switch1: added interface tap1 on port 1 2015-06-05T08:24:08.173Z|00019|rconn|INFO|switch1<->tcp:172.16.51.1::6633: connecting... 2015-06-05T08:24:08.173Z|00020|rconn|WARN|switch1<->tcp:172.16.51.1::6633: connection dropped (Connection refused) 2015-06-05T08:24:08.173Z|00021|rconn|INFO|switch1<->tcp:172.16.51.1::6633: waiting 2 seconds before reconnect 2015-06-05T08:24:09.675Z|00022|bridge|INFO|bridge switch1: added interface tun1 on port 2 2015-06-05T08:24:10.174Z|00023|rconn|INFO|switch1<->tcp:172.16.51.1::6633: connecting... 2015-06-05T08:24:10.174Z|00024|rconn|WARN|switch1<->tcp:172.16.51.1::6633: connection dropped (Connection refused) 2015-06-05T08:24:10.174Z|00025|rconn|INFO|switch1<->tcp:172.16.51.1::6633: waiting 4 seconds before reconnect 2015-06-05T08:24:11.676Z|00026|bridge|INFO|bridge switch1: added interface tun2 on port 3 2015-06-05T08:24:13.686Z|00027|bridge|INFO|bridge switch1: added interface tun3 on port 4 2015-06-05T08:24:14.173Z|00028|rconn|INFO|switch1<->tcp:172.16.51.1::6633: connecting... 2015-06-05T08:24:14.173Z|00029|rconn|WARN|switch1<->tcp:172.16.51.1::6633: connection dropped (Connection refused) 2015-06-05T08:24:14.173Z|00030|rconn|INFO|switch1<->tcp:172.16.51.1::6633: continuing to retry connections in the background but suppressing further logging 2015-06-05T08:24:17.580Z|00031|memory|INFO|3744 kB peak resident set size after 10.0 seconds 2015-06-05T08:24:17.580Z|00032|memory|INFO|handlers:8 ofconns:1 ports:5 revalidators:4 rules:5 2015-06-05T08:24:22.173Z|00033|fail_open|WARN|Could not connect to controller (or switch failed controller's post-connection admission control policy) for 15 seconds, failing open 2015-06-05T08:24:22.173Z|00034|rconn|WARN|switch1<->tcp:172.16.51.1::6633: connection dropped (Connection refused) 2015-06-05T08:24:30.173Z|00035|rconn|WARN|switch1<->tcp:172.16.51.1::6633: connection dropped (Connection refused) ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- Thanks, Hardik Soni
