Hi Eugene, there is also problem in my kvm test environment and the vm nic driver is virtio-net, after the log print the ovs-vswitchd is crashed(ovs-2.0.0,kernel 3.0.93). What do you think ? The log as follow: 2014-06-01T06:23:52.409Z|18349|dpif|WARN|system@ovs-system: failed to flow_del (No such file or directory) skb_priority(0),in_port(2),skb_mark(0),eth(src=00:16:3e:5d :a0:c4,dst=ff:ff:ff:ff:ff:ff),eth_type(0x8100),vlan(vid=52,pcp=0),encap(eth_type(0x0806),arp(sip=***,tip=255.255.255.255,op=2,sha=00:16:3e:5d:a0:c4,tha=00:1 6:3e:5d:a0:c4)) 2014-06-01T06:23:52.444Z|18350|dpif|WARN|system@ovs-system: failed to put[create] (Invalid argument) skb_priority(0),in_port(2),skb_mark(0/0),eth(src=00:16:3e:5d:a0: c4,dst=ff:ff:ff:ff:ff:ff),eth_type(0x8100),vlan(vid=52,pcp=0),encap(eth_type(0x0806),arp(sip=******/0.0.0.0,tip=255.255.255.255/0.0.0.0,op=2/0xff,sha=00:16:3e: 5d:a0:c4/00:00:00:00:00:00,tha=00:16:3e:5d:a0:c4/00:00:00:00:00:00)), actions:<empty>,***496 leftover bytes*** (00000000f101000060b5890000000000000000000000000000000 000000000000000000000000000000000000000000000001000f91100000080000000000000010000000000000056000000000000000100000000000000560000000000000000000000000000000000000000 0000008fed561a00000000beec561a0000000000000000000000000000000000000000ffff0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000ffffffff000000000000000000000000000000000000000000000000000000000000 0000000000000000000000000000ffffffff00000000000000000000ffffffff00000000ffffffffffffffffffffffff000000000000000000000000000000030000000000000000000000000100ffff00000 000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000) 2014-06-01T06:23:52.444Z|18351|ofproto_dpif|ERR|failed to install subfacet for which datapath reported hits 2014-06-01T06:23:55.196Z|00002|daemon(monitor)|ERR|1 crashes: pid 7773 died, killed (Segmentation fault), core dumped, restarting The coredump: Program terminated with signal 11, Segmentation fault. #0 0x00000000004466ee in find_table () (gdb) bt #0 0x00000000004466ee in find_table () #1 0x0000000000446a73 in destroy_table () #2 0x00007f7968135988 in ??
