[原]解决 OpenvSwitch terminating with signal 14 (Alarm clock) 错误 雨

在配置br-ex 桥接到eth0 网卡后,重启neutron-openvswitch-agent 服务后,一直提示报错,无法创建patch-int 和 patch-tun 网卡(极少时候是可以的)。
这导致openvswitch 在不断的重启,而对外的网络(与RabbitMQ 连接)也在不断的重启中。

1.排查
经排查,原因是Juno 版 neutron-openvswitch-agent 在计算节点环境下,重启时有部分遗留的mask 没有清除,导致加入patch-int 等port 的时候,OpenvSwitch 进程会出现异常。

在网络节点上采用相同的openvswitch 和 neutron-openvswitch-agent 与配置是正常的。

相关Bug:
Bug 1185521 - ovs-vswitchd crash [NEEDINFO]
https://bugzilla.redhat.com/show_bug.cgi?id=1185521

2.解决
升级到 openvswitch-2.1.2-2.el7.centos.2.x86_64.rpm 即可。
